How can patients with dementia indicate discomfort exists?


Facial grimacing and guarding indicate what?

When a person is non-verbal and cannot self-report pain, observation becomes critical, and specific behaviors can be monitored as pain indicators. Behaviors such as facial grimacing and guarding indicate pain, as well as an increase or decrease in vocalizations, changes in routine behavior patterns and mental status changes. Patients experiencing pain may exhibit withdrawn social behavior and possibly experience a decreased appetite and decreased nutritional intake. A change in condition that deviates from baseline such as moaning with movement or when manipulating a body part, and limited range of motion are also potential pain indicators. In patients who possess language but are incapable of expressing themselves effectively, such as those with dementia, an increase in confusion or display of aggressive behaviors or agitation may signal that discomfort exists, and further assessment is necessary.


Why may older adults quit doing activities the love?

The experience of pain has many cultural dimensions. For instance, the way in which one experiences and responds to pain is related to sociocultural characteristics, such as gender, ethnicity, and age. An aging adult may not respond to pain in the way that a younger person would. Their ability to recognize pain may be blunted by illness or the use of multiple prescription drugs. Depression may also keep the older adult from reporting they are in pain. The older adult may also quit doing activities they love because it hurts too much. Decline in self-care activities (dressing, grooming, walking, etc.) may also be indicators that the older adult is experiencing pain. The older adult may refrain from reporting pain because they are afraid they will have to have surgery or will be put on a drug they might become addicted to. They may not want others to see them as weak, or may feel there is something impolite or shameful in complaining about pain, or they may feel the pain is deserved punishment for past transgressions.

What kind of barriers can prevent a person from telling someone they're in pain?

Cultural barriers can also keep a person from telling someone they are in pain. Religious beliefs may prevent the individual from seeking help. They may feel certain pain treatment is against their religion. They may not report pain because they feel it is a sign that death is near. Many people fear the stigma of addiction and avoid pain treatment so as not to be prescribed potentially addicting drugs. Many Asians do not want to lose respect in society by admitting they are in pain and need help, believing the pain should be borne in silence, while other cultures feel they should report pain right away and get immediate relief. Gender can also be a factor in reporting pain. Sexual differences can be the result of social and cultural expectations, with women expected to be emotional and show pain and men stoic, keeping pain to themselves.

What does the IASP advocate that the relief of pain should be recognized as?

The International Association for the Study of Pain advocates that the relief of pain should be recognized as a human right, that chronic pain should be considered a disease in its own right, and that pain medicine should have the full status of a specialty. It is a specialty only in China and Australia at this time. Elsewhere, pain medicine is a subspecialty under disciplines such as anesthesiology, physiatry, neurology, palliative medicine and psychiatry. In 2011, Human Rights Watch alerted that tens of millions of people worldwide are still denied access to inexpensive medications for severe pain.

What, when taken orally, can reduce total crying time of newsborns undergoing a painful procedure?

Sugar taken orally reduces the total crying time but not the duration of the first cry in newborns undergoing a painful procedure (a single lancing of the heel). It does not moderate the effect of pain on heart rate and a recent single study found that sugar did not significantly affect pain-related electrical activity in the brains of newborns one second after the heel lance procedure. Sweet oral liquid moderately reduces the incidence and duration of crying caused by immunization injection in children between one and twelve months of age.

Clinical hypnosis may be effective in doing what with pain associated with surgical procedures in adults and children?

A number of meta-analyses have found clinical hypnosis to be effective in controlling pain associated with diagnostic and surgical procedures in both adults and children, as well as pain associated with cancer and childbirth. A 2007 review of 13 studies found evidence for the efficacy of hypnosis in the reduction of chronic pain in some conditions, though the number of patients enrolled in the studies was low, bringing up issues of power to detect group differences, and most lacked credible controls for placebo and/or expectation. The authors concluded that "although the findings provide support for the general applicability of hypnosis in the treatment of chronic pain, considerably more research will be needed to fully determine the effects of hypnosis for different chronic-pain conditions."

What is the most common reason people seek out alternative medicine?

Pain is the most common reason for people to use complementary and alternative medicine. An analysis of the 13 highest quality studies of pain treatment with acupuncture, published in January 2009, concluded there is little difference in the effect of real, sham and no acupuncture. However other reviews have found benefit. Additionally, there is tentative evidence for a few herbal medicine. There is interest in the relationship between vitamin D and pain, but the evidence so far from controlled trials for such a relationship, other than in osteomalacia, is unconvincing.

What type of topic is physical pain important in relation to many issues?

Physical pain is an important political topic in relation to various issues, including pain management policy, drug control, animal rights or animal welfare, torture, and pain compliance. In various contexts, the deliberate infliction of pain in the form of corporal punishment is used as retribution for an offence, or for the purpose of disciplining or reforming a wrongdoer, or to deter attitudes or behaviour deemed unacceptable. In some cultures, extreme practices such as mortification of the flesh or painful rites of passage are highly regarded.

What is the most reliable method of learning about pain in a human?

The most reliable method for assessing pain in most humans is by asking a question: a person may report pain that cannot be detected by any known physiological measure. However, like infants (Latin infans meaning "unable to speak"), animals cannot answer questions about whether they feel pain; thus the defining criterion for pain in humans cannot be applied to them. Philosophers and scientists have responded to this difficulty in a variety of ways. René Descartes for example argued that animals lack consciousness and therefore do not experience pain and suffering in the way that humans do. Bernard Rollin of Colorado State University, the principal author of two U.S. federal laws regulating pain relief for animals, writes that researchers remained unsure into the 1980s as to whether animals experience pain, and that veterinarians trained in the U.S. before 1989 were simply taught to ignore animal pain. In his interactions with scientists and other veterinarians, he was regularly asked to "prove" that animals are conscious, and to provide "scientifically acceptable" grounds for claiming that they feel pain. Carbone writes that the view that animals feel pain differently is now a minority view. Academic reviews of the topic are more equivocal, noting that although the argument that animals have at least simple conscious thoughts and feelings has strong support, some critics continue to question how reliably animal mental states can be determined. The ability of invertebrate species of animals, such as insects, to feel pain and suffering is also unclear.


What university is Bernard Rollin associated with?


Can invertebrate species of animals like insects feel pain and suffering?


What about pain in an animal isn't able to be known with certainty?

The presence of pain in an animal cannot be known for certain, but it can be inferred through physical and behavioral reactions. Specialists currently believe that all vertebrates can feel pain, and that certain invertebrates, like the octopus, might too. As for other animals, plants, or other entities, their ability to feel physical pain is at present a question beyond scientific reach, since no mechanism is known by which they could have such a feeling. In particular, there are no known nociceptors in groups such as plants, fungi, and most insects, except for instance in fruit flies.

A database management system (DBMS) is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases. Well-known DBMSs include MySQL, PostgreSQL, Microsoft SQL Server, Oracle, Sybase, SAP HANA, and IBM DB2. A database is not generally portable across different DBMSs, but different DBMS can interoperate by using standards such as SQL and ODBC or JDBC to allow a single application to work with more than one DBMS. Database management systems are often classified according to the database model that they support; the most popular database systems since the 1980s have all supported the relational model as represented by the SQL language.[disputed – discuss] Sometimes a DBMS is loosely referred to as a 'database'.


Formally, a "database" refers to a set of related data and the way it is organized. Access to these data is usually provided by a "database management system" (DBMS) consisting of an integrated set of computer software that allows users to interact with one or more databases and provides access to all of the data contained in the database (although restrictions may exist that limit access to particular data). The DBMS provides various functions that allow entry, storage and retrieval of large quantities of information and provides ways to manage how that information is organized.


What do most database applications contain?

Physically, database servers are dedicated computers that hold the actual databases and run only the DBMS and related software. Database servers are usually multiprocessor computers, with generous memory and RAID disk arrays used for stable storage. RAID is used for recovery of data if any of the disks fail. Hardware database accelerators, connected to one or more servers via a high-speed channel, are also used in large volume transaction processing environments. DBMSs are found at the heart of most database applications. DBMSs may be built around a custom multitasking kernel with built-in networking support, but modern DBMSs typically rely on a standard operating system to provide these functions. from databases before the inception of Structured Query Language (SQL). The data recovered was disparate, redundant and disorderly, since there was no proper method to fetch it and arrange it in a concrete structure.[citation needed]


What is used to recover data if disks suffer a failure?


How can large quantities of data be accessed?


What is required for a modern DBMS to function?


A DBMS has evolved into a complex software system and its development typically requires thousands of human years of development effort.[a] Some general-purpose DBMSs such as Adabas, Oracle and DB2 have been undergoing upgrades since the 1970s. General-purpose DBMSs aim to meet the needs of as many applications as possible, which adds to the complexity. However, the fact that their development cost can be spread over a large number of users means that they are often the most cost-effective approach. However, a general-purpose DBMS is not always the optimal solution: in some cases a general-purpose DBMS may introduce unnecessary overhead. Therefore, there are many examples of systems that use special-purpose databases. A common example is an email system that performs many of the functions of a general-purpose DBMS such as the insertion and deletion of messages composed of various items of data or associating messages with a particular email address; but these functions are limited to what is required to handle email and don't provide the user with all of the functionality that would be available using a general-purpose DBMS.

How is the cost to create a DBMS distributed?


Name an example of a general-purpose DBMS.


Many other databases have application software that accesses the database on behalf of end-users, without exposing the DBMS interface directly. Application programmers may use a wire protocol directly, or more likely through an application programming interface. Database designers and database administrators interact with the DBMS through dedicated interfaces to build and maintain the applications' databases, and thus need some more knowledge and understanding about how DBMSs operate and the DBMSs' external interfaces and tuning parameters.


How do administrators work with the DBMS?

Who created the relational model of DBMS?

The relational model, first proposed in 1970 by Edgar F. Codd, departed from this tradition by insisting that applications should search for data by content, rather than by following links. The relational model employs sets of ledger-style tables, each used for a different type of entity. Only in the mid-1980s did computing hardware become powerful enough to allow the wide deployment of relational systems (DBMSs plus applications). By the early 1990s, however, relational systems dominated in all large-scale data processing applications, and as of 2015[update] they remain dominant : IBM DB2, Oracle, MySQL and Microsoft SQL Server are the top DBMS. The dominant database language, standardised SQL for the relational model, has influenced database languages for other data models.[citation needed]


Instead of using links, how was information found in a relational model?


In what decade did computer hardware become able to handle a relational system?


What type of system in still prominent to this day?


What database language is the most prominent?


As computers grew in speed and capability, a number of general-purpose database systems emerged; by the mid-1960s a number of such systems had come into commercial use. Interest in a standard began to grow, and Charles Bachman, author of one such product, the Integrated Data Store (IDS), founded the "Database Task Group" within CODASYL, the group responsible for the creation and standardization of COBOL. In 1971 the Database Task Group delivered their standard, which generally became known as the "CODASYL approach", and soon a number of commercial products based on this approach entered the market.


When were DBMSs first used commercially?


When was the standard protocol completed?


What was the DBMS created by IBM called?

IBM also had their own DBMS in 1966, known as Information Management System (IMS). IMS was a development of software written for the Apollo program on the System/360. IMS was generally similar in concept to CODASYL, but used a strict hierarchy for its model of data navigation instead of CODASYL's network model. Both concepts later became known as navigational databases due to the way data was accessed, and Bachman's 1973 Turing Award presentation was The Programmer as Navigator. IMS is classified[by whom?] as a hierarchical database. IDMS and Cincom Systems' TOTAL database are classified as network databases. IMS remains in use as of 2014[update].


What was the name of Bachman's Turing Award presentation in 1973?


Who proposed using a table to store data?

In this paper, he described a new system for storing and working with large databases. Instead of records being stored in some sort of linked list of free-form records as in CODASYL, Codd's idea was to use a "table" of fixed-length records, with each table used for a different type of entity. A linked-list system would be very inefficient when storing "sparse" databases where some of the data for any one record could be left empty. The relational model solved this by splitting the data into a series of normalized tables (or relations), with optional elements being moved out of the main table to where they would take up room only if needed. Data may be freely inserted, deleted and edited in these tables, with the DBMS doing whatever maintenance needed to present a table view to the application/user.


What model solved the problem of databases where information was missing?


What system assists a user in seeing a table?


How was the relational model able to improve over time?

The relational model also allowed the content of the database to evolve without constant rewriting of links and pointers. The relational part comes from entities referencing other entities in what is known as one-to-many relationship, like a traditional hierarchical model, and many-to-many relationship, like a navigational (network) model. Thus, a relational model can express both hierarchical and navigational models, as well as its native tabular model, allowing for pure or combined modeling in terms of these three models, as the application requires.


What is the relationship called in a hierarchical model?


What is the relationship called in a navigational model?


What is a third type of model that can be combined with heirarchical and navigation models?


How is information stored in a navigational system?

For instance, a common use of a database system is to track information about users, their name, login information, various addresses and phone numbers. In the navigational approach all of this data would be placed in a single record, and unused items would simply not be placed in the database. In the relational approach, the data would be normalized into a user table, an address table and a phone number table (for instance). Records would be created in these optional tables only if the address or phone numbers were actually provided.


How is a database system frequently used?


How is information stored in a relational system?


What happens to blank data fields in a navigational system?


Linking the information back together is the key to this system. In the relational model, some bit of information was used as a "key", uniquely defining a particular record. When information was being collected about a user, information stored in the optional tables would be found by searching for this key. For instance, if the login name of a user is unique, addresses and phone numbers for that user would be recorded with the login name as its key. This simple "re-linking" of related data back into a single collection is something that traditional computer languages are not designed for.


What technique is used to collect into one place?


How is information accessed in a relational model?


How is data in an optional table accessed?


How does a program collect information using a navigational system?

Just as the navigational approach would require programs to loop in order to collect records, the relational approach would require loops to collect information about any one record. Codd's solution to the necessary looping was a set-oriented language, a suggestion that would later spawn the ubiquitous SQL. Using a branch of mathematics known as tuple calculus, he demonstrated that such a system could support all the operations of normal databases (inserting, updating etc.) as well as providing a simple system for finding and returning sets of data in a single operation.

Who used Codd's paper at Berkeley to improve a geographical database?

Codd's paper was picked up by two people at Berkeley, Eugene Wong and Michael Stonebraker. They started a project known as INGRES using funding that had already been allocated for a geographical database project and student programmers to produce code. Beginning in 1973, INGRES delivered its first test products which were generally ready for widespread use in 1979. INGRES was similar to System R in a number of ways, including the use of a "language" for data access, known as QUEL. Over time, INGRES moved to the emerging SQL standard.


What was the name of the project to create a geographical database?


What computer language was used in INGRES to access data?


Is QUEL still used to access data in INGRES?


Another approach to hardware support for database management was ICL's CAFS accelerator, a hardware disk controller with programmable search capabilities. In the long term, these efforts were generally unsuccessful because specialized database machines could not keep pace with the rapid development and progress of general-purpose computers. Thus most database systems nowadays are software systems running on general-purpose hardware, using general-purpose computer data storage. However this idea is still pursued for certain applications by some companies like Netezza and Oracle (Exadata).


Did the CAFS accelerator work as planned?


Name a company that is still working on the CAFS accellerator?


What is the system IBM created using Codd's research?

IBM started working on a prototype system loosely based on Codd's concepts as System R in the early 1970s. The first version was ready in 1974/5, and work then started on multi-table systems in which the data could be split so that all of the data for a record (some of which is optional) did not have to be stored in a single large "chunk". Subsequent multi-user versions were tested by customers in 1978 and 1979, by which time a standardized query language – SQL[citation needed] – had been added. Codd's ideas were establishing themselves as both workable and superior to CODASYL, pushing IBM to develop a true production version of System R, known as SQL/DS, and, later, Database 2 (DB2).


What did System R work on to change the way data was stored?

What was the name of the database product created by IBM?


The 1980s ushered in the age of desktop computing. The new computers empowered their users with spreadsheets like Lotus 1-2-3 and database software like dBASE. The dBASE product was lightweight and easy for any computer user to understand out of the box. C. Wayne Ratliff the creator of dBASE stated: "dBASE was different from programs like BASIC, C, FORTRAN, and COBOL in that a lot of the dirty work had already been done. The data manipulation is done by dBASE instead of by the user, so the user can concentrate on what he is doing, rather than having to mess with the dirty details of opening, reading, and closing files, and managing space allocation." dBASE was one of the top selling software titles in the 1980s and early 1990s.


In the 1990s, what type of programming changed the handling of databases?

The 1990s, along with a rise in object-oriented programming, saw a growth in how data in various databases were handled. Programmers and designers began to treat the data in their databases as objects. That is to say that if a person's data were in a database, that person's attributes, such as their address, phone number, and age, were now considered to belong to that person instead of being extraneous data. This allows for relations between data to be relations to objects and their attributes and not to individual fields. The term "object-relational impedance mismatch" described the inconvenience of translating between programmed objects and database tables. Object databases and object-relational databases attempt to solve this problem by providing an object-oriented language (sometimes as extensions to SQL) that programmers can use as alternative to purely relational SQL. On the programming side, libraries known as object-relational mappings (ORMs) attempt to solve the same problem.

XML databases are a type of structured document-oriented database that allows querying based on XML document attributes. XML databases are mostly used in enterprise database management, where XML is being used as the machine-to-machine data interoperability standard. XML database management systems include commercial software MarkLogic and Oracle Berkeley DB XML, and a free use software Clusterpoint Distributed XML/JSON Database. All are enterprise software database platforms and support industry standard ACID-compliant transaction processing with strong database consistency characteristics and high level of database security.

What is used to offer a balance in guarantees?

In recent years there was a high demand for massively distributed databases with high partition tolerance but according to the CAP theorem it is impossible for a distributed system to simultaneously provide consistency, availability and partition tolerance guarantees. A distributed system can satisfy any two of these guarantees at the same time, but not all three. For that reason many NoSQL databases are using what is called eventual consistency to provide both availability and partition tolerance guarantees with a reduced level of data consistency.


What explains the difficulty in a system containing availability, consistency, and partition tolerance guarantees?


How many guarantees will most databases tolerate?


The first task of a database designer is to produce a conceptual data model that reflects the structure of the information to be held in the database. A common approach to this is to develop an entity-relationship model, often with the aid of drawing tools. Another popular approach is the Unified Modeling Language. A successful data model will accurately reflect the possible state of the external world being modeled: for example, if people can have more than one phone number, it will allow this information to be captured. Designing a good conceptual data model requires a good understanding of the application domain; it typically involves asking deep questions about the things of interest to an organisation, like "can a customer also be a supplier?", or "if a product is sold with two different forms of packaging, are those the same product or different products?", or "if a plane flies from New York to Dubai via Frankfurt, is that one flight or two (or maybe even three)?". The answers to these questions establish definitions of the terminology used for entities (customers, products, flights, flight segments) and their relationships and attributes.


Asking questions about an organization's needs will help to create what?


What must one understand in order to create a successful data model?


A conceptual data model in separate from the choice of what?

Having produced a conceptual data model that users are happy with, the next stage is to translate this into a schema that implements the relevant data structures within the database. This process is often called logical database design, and the output is a logical data model expressed in the form of a schema. Whereas the conceptual data model is (in theory at least) independent of the choice of database technology, the logical data model will be expressed in terms of a particular database model supported by the chosen DBMS. (The terms data model and database model are often used interchangeably, but in this article we use data model for the design of a specific database, and database model for the modelling notation used to express that design.)


In what form is the output of a logical database design?


Which data model is displayed as a specific model that uses DBMS?


What decisions must be made in the last stage of database design?

The final stage of database design is to make the decisions that affect performance, scalability, recovery, security, and the like. This is often called physical database design. A key goal during this stage is data independence, meaning that the decisions made for performance optimization purposes should be invisible to end-users and applications. Physical design is driven mainly by performance requirements, and requires a good knowledge of the expected workload and access patterns, and a deep understanding of the features offered by the chosen DBMS.


What is an important goal in in this final stage?


What factor is reflected in performance requirements?


How many conceptual or physical views of data are there?

While there is typically only one conceptual (or logical) and physical (or internal) view of the data, there can be any number of different external views. This allows users to see database information in a more business-related way rather than from a technical, processing viewpoint. For example, a financial department of a company needs the payment details of all employees as part of the company's expenses, but does not need details about employees that are the interest of the human resources department. Thus different departments need different views of the company's database.


How many different external views of data are there?


What is the benefit of external views of data?


The conceptual view provides a level of indirection between internal and external. On one hand it provides a common view of the database, independent of different external view structures, and on the other hand it abstracts away details of how the data are stored or managed (internal level). In principle every level, and even every external view, can be presented by a different data model. In practice usually a given DBMS uses the same data model for both the external and the conceptual levels (e.g., relational model). The internal level, which is hidden inside the DBMS and depends on its implementation, requires a different level of detail and uses its own types of data structure types.


How does the conceptual view handle how data is managed?


What type of view does the conceptual view offer?


What is responsible for putting information into permanent storage?

Database storage is the container of the physical materialization of a database. It comprises the internal (physical) level in the database architecture. It also contains all the information needed (e.g., metadata, "data about the data", and internal data structures) to reconstruct the conceptual level and external level from the internal level when needed. Putting data into permanent storage is generally the responsibility of the database engine a.k.a. "storage engine". Though typically accessed by a DBMS through the underlying operating system (and often utilizing the operating systems' file systems as intermediates for storage layout), storage properties and configuration setting are extremely important for the efficient operation of the DBMS, and thus are closely maintained by database administrators. A DBMS, while in operation, always has its database residing in several types of storage (e.g., memory and external storage). The database data and the additional needed information, possibly in very large amounts, are coded into bits. Data typically reside in the storage in structures that look completely different from the way the data look in the conceptual and external levels, but in ways that attempt to optimize (the best possible) these levels' reconstruction when needed by users and programs, as well as for computing additional types of needed information from the data (e.g., when querying the database).


What do database administrators closely monitor?


While working, does DBMS store information in one place?


What are huge quantities of information stored as?


Database access control deals with controlling who (a person or a certain computer program) is allowed to access what information in the database. The information may comprise specific database objects (e.g., record types, specific records, data structures), certain computations over certain objects (e.g., query types, or specific queries), or utilizing specific access paths to the former (e.g., using specific indexes or other data structures to access information). Database access controls are set by special authorized (by the database owner) personnel that uses dedicated protected security DBMS interfaces.


This may be managed directly on an individual basis, or by the assignment of individuals and privileges to groups, or (in the most elaborate models) through the assignment of individuals and groups to roles which are then granted entitlements. Data security prevents unauthorized users from viewing or updating the database. Using passwords, users are allowed access to the entire database or subsets of it called "subschemas". For example, an employee database can contain all the data about an individual employee, but one group of users may be authorized to view only payroll data, while others are allowed access to only work history and medical data. If the DBMS provides a way to interactively enter and update the database, as well as interrogate it, this capability allows for managing personal databases.


What is a subset of a database called that can be accessed by using a password?


What is possible when a DBMS interrogate and update a database?


What is a unit of work called in a database?

Database transactions can be used to introduce some level of fault tolerance and data integrity after recovery from a crash. A database transaction is a unit of work, typically encapsulating a number of operations over a database (e.g., reading a database object, writing, acquiring lock, etc.), an abstraction supported in database and also other systems. Each transaction has well defined boundaries in terms of which program/code executions are included in that transaction (determined by the transaction's programmer via special transaction commands).


How can database transactions ensure accuracy after a crash?


Why would someone attempt to unite two different databases?

A database built with one DBMS is not portable to another DBMS (i.e., the other DBMS cannot run it). However, in some situations it is desirable to move, migrate a database from one DBMS to another. The reasons are primarily economical (different DBMSs may have different total costs of ownership or TCOs), functional, and operational (different DBMSs may have different capabilities). The migration involves the database's transformation from one DBMS type to another. The transformation should maintain (if possible) the database related application (i.e., all related application programs) intact. Thus, the database's conceptual and external architectural levels should be maintained in the transformation. It may be desired that also some aspects of the architecture internal level are maintained. A complex or large database migration may be a complicated and costly (one-time) project by itself, which should be factored into the decision to migrate. This in spite of the fact that tools may exist to help migration between specific DBMSs. Typically a DBMS vendor provides tools to help importing databases from other popular DBMSs.

Name a reason to take a database backward in time?

Sometimes it is desired to bring a database back to a previous state (for many reasons, e.g., cases when the database is found corrupted due to a software error, or if it has been updated with erroneous data). To achieve this a backup operation is done occasionally or continuously, where each desired database state (i.e., the values of its data and their embedding in database's data structures) is kept within dedicated backup files (many techniques exist to do this effectively). When this state is needed, i.e., when it is decided by a database administrator to bring the database back to this state (e.g., by specifying this state by a desired point in time when the database was in this state), these files are utilized to restore that state.

Static analysis techniques for software verification can be applied also in the scenario of query languages. In particular, the *Abstract interpretation framework has been extended to the field of query languages for relational databases as a way to support sound approximation techniques. The semantics of query languages can be tuned according to suitable abstractions of the concrete domain of data. The abstraction of relational database system has many interesting applications, in particular, for security purposes, such as fine grained access control, watermarking, etc.

What was Tuscon known as 12,000 years ago?

Tucson was probably first visited by Paleo-Indians, known to have been in southern Arizona about 12,000 years ago. Recent archaeological excavations near the Santa Cruz River have located a village site dating from 2100 BC.[citation needed] The floodplain of the Santa Cruz River was extensively farmed during the Early Agricultural period, circa 1200 BC to AD 150. These people constructed irrigation canals and grew corn, beans, and other crops while gathering wild plants and hunting. The Early Ceramic period occupation of Tucson saw the first extensive use of pottery vessels for cooking and storage. The groups designated as the Hohokam lived in the area from AD 600 to 1450 and are known for their vast irrigation canal systems and their red-on-brown pottery.[citation needed]

Jesuit missionary Eusebio Francisco Kino visited the Santa Cruz River valley in 1692, and founded the Mission San Xavier del Bac in 1700 about 7 mi (11 km) upstream from the site of the settlement of Tucson. A separate Convento settlement was founded downstream along the Santa Cruz River, near the base of what is now "A" mountain. Hugo O'Conor, the founding father of the city of Tucson, Arizona authorized the construction of a military fort in that location, Presidio San Agustín del Tucsón, on August 20, 1775 (near the present downtown Pima County Courthouse). During the Spanish period of the presidio, attacks such as the Second Battle of Tucson were repeatedly mounted by Apaches. Eventually the town came to be called "Tucson" and became a part of Sonora after Mexico gained independence from Spain in 1821.

What date did William Whitney Brazelton Die?

From 1877 to 1878, the area suffered a rash of stagecoach robberies. Most notable, however, were the two holdups committed by masked road-agent William Whitney Brazelton. Brazelton held up two stages in the summer of 1878 near Point of Mountain Station approximately 17 mi (27 km) northwest of Tucson. John Clum, of Tombstone, Arizona fame was one of the passengers. Brazelton was eventually tracked down and killed on Monday August 19, 1878, in a mesquite bosque along the Santa Cruz River 3 miles (5 km) south of Tucson by Pima County Sheriff Charles A. Shibell and his citizen's posse. Brazelton had been suspected of highway robbery not only in the Tucson area, but also in the Prescott region and Silver City, New Mexico area as well. Brazelton's crimes prompted John J. Valentine, Sr. of Wells, Fargo & Co. to send special agent and future Pima County sheriff Bob Paul to investigate. Fort Lowell, then east of Tucson, was established to help protect settlers from Apache attacks. In 1882, Frank Stilwell was implicated in the murder of Morgan Earp by Cowboy Pete Spence's wife, Marietta, at the coroner's inquest on Morgan Earp's shooting. The coroner's jury concluded that Spence, Stilwell, Frederick Bode, and Florentino "Indian Charlie" Cruz were the prime suspects in the assassination of Morgan Earp. :250 Deputy U.S. Marshal Wyatt Earp gathered a few trusted friends and accompanied Virgil Earp and his family as they traveled to Benson for a train ride to California. They found Stilwell lying in wait for Virgil in the Tucson station and killed him on the tracks. After killing Stilwell, Wyatt deputized others and rode on a vendetta, killing three more cowboys over the next few days before leaving the state.

What else is Sentinel Peak also known as?

On Sentinel Peak (also known as "'A' Mountain"), just west of downtown, there is a giant "A" in honor of the University of Arizona. Starting in about 1916, a yearly tradition developed for freshmen to whitewash the "A", which was visible for miles. However, at the beginning of the Iraq War, anti-war activists painted it black. This was followed by a paint scuffle where the "A" was painted various colors until the city council intervened. It is now red, white and blue except when it is white or another color decided by a biennial election. Because of the three-color paint scheme often used, the shape of the A can be vague and indistinguishable from the rest of the peak. The top of Sentinel Peak, which is accessible by road, offers an outstanding scenic view of the city looking eastward. A parking lot located near the summit of Sentinel Peak was formerly a popular place to watch sunsets or view the city lights at night.

Near the intersection of Craycroft and Ft. Lowell Roads are the remnants of the Historic Fort Lowell. This area has become one of Tucson's iconic neighborhoods. In 1891, the Fort was abandoned and much of the interior was stripped of their useful components and it quickly fell into ruin. In 1900, three of the officer buildings were purchased for use as a sanitarium. The sanitarium was then sold to Harvey Adkins in 1928. The Bolsius family Pete, Nan and Charles Bolsius purchased and renovated surviving adobe buildings of the Fort – transforming them into spectacular artistic southwestern architectural examples. Their woodwork, plaster treatment and sense of proportion drew on their Dutch heritage and New Mexican experience. Other artists and academics throughout the middle of the 20th century, including: Win Ellis, Jack Maul, Madame Cheruy, Giorgio Belloli, Charels Bode, Veronica Hughart, Edward and Rosamond Spicer, Hazel Larson Archer and Ruth Brown, renovated adobes, built homes and lived in the area. The artist colony attracted writers and poets including beat generation Alan Harrington and Jack Kerouac whose visit is documented in his iconic book On the Road. This rural pocket in the middle of the city is listed on the National Register of Historic Places. Each year in February the neighborhood celebrates its history in the City Landmark it owns and restored the San Pedro Chapel.

Tucson has a desert climate (Köppen BWh), with two major seasons, summer and winter; plus three minor seasons: fall, spring, and the monsoon. Tucson averages 11.8 inches (299.7 mm) of precipitation per year, more than most other locations with desert climates, but it still qualifies due to its high evapotranspiration; in other words, it experiences a high net loss of water. A similar scenario is seen in Alice Springs, Australia, which averages 11 inches (279.4 mm) a year, but has a desert climate.

What year did the "Stupid Motorist Law" come in effect?

The monsoon can begin any time from mid-June to late July, with an average start date around July 3. It typically continues through August and sometimes into September. During the monsoon, the humidity is much higher than the rest of the year. It begins with clouds building up from the south in the early afternoon followed by intense thunderstorms and rainfall, which can cause flash floods. The evening sky at this time of year is often pierced with dramatic lightning strikes. Large areas of the city do not have storm sewers, so monsoon rains flood the main thoroughfares, usually for no longer than a few hours. A few underpasses in Tucson have "feet of water" scales painted on their supports to discourage fording by automobiles during a rainstorm. Arizona traffic code Title 28-910, the so-called "Stupid Motorist Law", was instituted in 1995 to discourage people from entering flooded roadways. If the road is flooded and a barricade is in place, motorists who drive around the barricade can be charged up to $2000 for costs involved in rescuing them. Despite all warnings and precautions, however, three Tucson drivers have drowned between 2004 and 2010.

Tucson is commonly known as "The Old Pueblo". While the exact origin of this nickname is uncertain, it is commonly traced back to Mayor R. N. "Bob" Leatherwood. When rail service was established to the city on March 20, 1880, Leatherwood celebrated the fact by sending telegrams to various leaders, including the President of the United States and the Pope, announcing that the "ancient and honorable pueblo" of Tucson was now connected by rail to the outside world. The term became popular with newspaper writers who often abbreviated it as "A. and H. Pueblo". This in turn transformed into the current form of "The Old Pueblo".

Both the council members and the mayor serve four-year terms; none face term limits. Council members are nominated by their wards via a ward-level primary held in September. The top vote-earners from each party then compete at-large for their ward's seat on the November ballot. In other words, on election day the whole city votes on all the council races up for that year. Council elections are severed: Wards 1, 2, and 4 (as well as the mayor) are up for election in the same year (most recently 2011), while Wards 3, 5, and 6 share another year (most recently 2013).

When did Tucson begin offering city council candidates public funding?

Tucson is known for being a trailblazer in voluntary partial publicly financed campaigns. Since 1985, both mayoral and council candidates have been eligible to receive matching public funds from the city. To become eligible, council candidates must receive 200 donations of $10 or more (300 for a mayoral candidate). Candidates must then agree to spending limits equal to 33¢ for every registered Tucson voter, or $79,222 in 2005 (the corresponding figures for mayor are 64¢ per registered voter, or $142,271 in 2003). In return, candidates receive matching funds from the city at a 1:1 ratio of public money to private donations. The only other limitation is that candidates may not exceed 75% of the limit by the date of the primary. Many cities, such as San Francisco and New York City, have copied this system, albeit with more complex spending and matching formulas.

Tucson's primary electrical power source is a coal and natural gas power-plant managed by Tucson Electric Power that is situated within the city limits on the south-western boundary of Davis-Monthan Air-force base adjacent to Interstate-10. The air pollution generated has raised some concerns as the Sundt operating station has been online since 1962 as is exempt from many pollution standards and controls due to its age. Solar has been gaining ground in Tucson with its ideal over 300 days of sunshine climate. Federal, state, and even local utility credits and incentives have also enticed residents to equip homes with solar systems. Davis-Monthan AFB has a 3.3 Megawatt (MW) ground-mounted solar photovoltaic (PV) array and a 2.7 MW rooftop-mounted PV array, both of which are located in the Base Housing area. The base will soon have the largest solar-generating capacity in the United States Department of Defense after awarding a contract on September 10, 2010, to SunEdison to construct a 14.5 MW PV field on the northwestern side of the base.

Perhaps the biggest sustainability problem in Tucson, with its high desert climate, is potable water supply. The state manages all water in Arizona through its Arizona Department of Water Resources (ADWR). The primary consumer of water is Agriculture (including golf courses), which consumes about 69% of all water. Municipal (which includes residential use) accounts for about 25% of use. Energy consumption and availability is another sustainability issue. However, with over 300 days of full sun a year, Tucson has demonstrated its potential to be an ideal solar energy producer.

How is Tucson replenishing its groundwater?

In an effort to conserve water, Tucson is recharging groundwater supplies by running part of its share of CAP water into various open portions of local rivers to seep into their aquifer. Additional study is scheduled to determine the amount of water that is lost through evaporation from the open areas, especially during the summer. The City of Tucson already provides reclaimed water to its inhabitants, but it is only used for "applications such as irrigation, dust control, and industrial uses." These resources have been in place for more than 27 years, and deliver to over 900 locations.


What does Tucson use reclaimed water for?


How long has Tucson's water conservation efforts been underway?


To prevent further loss of groundwater, Tucson has been involved in water conservation and groundwater preservation efforts, shifting away from its reliance on a series of Tucson area wells in favor of conservation, consumption-based pricing for residential and commercial water use, and new wells in the more sustainable Avra Valley aquifer, northwest of the city. An allocation from the Central Arizona Project Aqueduct (CAP), which passes more than 300 mi (480 km) across the desert from the Colorado River, has been incorporated into the city's water supply, annually providing over 20 million gallons of "recharged" water which is pumped into the ground to replenish water pumped out. Since 2001, CAP water has allowed the city to remove or turn off over 80 wells.

Armenia is a unitary, multi-party, democratic nation-state with an ancient cultural heritage. Urartu was established in 860 BC and by the 6th century BC it was replaced by the Satrapy of Armenia. In the 1st century BC the Kingdom of Armenia reached its height under Tigranes the Great. Armenia became the first state in the world to adopt Christianity as its official religion. In between the late 3rd century to early years of the 4th century, the state became the first Christian nation. The official date of state adoption of Christianity is 301 AD. The ancient Armenian kingdom was split between the Byzantine and Sasanian Empires around the early 5th century.

What two empires did Armenia belong to in the beginning of the 5th century?


Which two empires ruled Armenia between the 16 and 19th Century?

Between the 16th century and 19th century, the traditional Armenian homeland composed of Eastern Armenia and Western Armenia came under the rule of the Ottoman and successive Iranian empires, repeatedly ruled by either of the two over the centuries. By the 19th century, Eastern Armenia had been conquered by the Russian Empire, while most of the western parts of the traditional Armenian homeland remained under Ottoman rule. During World War I, Armenians living in their ancestral lands in the Ottoman Empire were systematically exterminated in the Armenian Genocide. In 1918, after the Russian Revolution, all non-Russian countries declared their independence from the Russian empire, leading to the establishment of the First Republic of Armenia. By 1920, the state was incorporated into the Transcaucasian Socialist Federative Soviet Republic, and in 1922 became a founding member of the Soviet Union. In 1936, the Transcaucasian state was dissolved, transforming its constituent states, including the Armenian Soviet Socialist Republic, into full Union republics. The modern Republic of Armenia became independent in 1991 during the dissolution of the Soviet Union.

The exonym Armenia is attested in the Old Persian Behistun Inscription (515 BC) as Armina (  ). The ancient Greek terms Ἀρμενία (Armenía) and Ἀρμένιοι (Arménioi, "Armenians") are first mentioned by Hecataeus of Miletus (c. 550 BC – c. 476 BC). Xenophon, a Greek general serving in some of the Persian expeditions, describes many aspects of Armenian village life and hospitality in around 401 BC. He relates that the people spoke a language that to his ear sounded like the language of the Persians. According to the histories of both Moses of Chorene and Michael Chamchian, Armenia derives from the name of Aram, a lineal descendant of Hayk.

When was the capital of Armenia established?

Several bronze-era states flourished in the area of Greater Armenia, including the Hittite Empire (at the height of its power), Mitanni (South-Western historical Armenia), and Hayasa-Azzi (1500–1200 BC). The Nairi people (12th to 9th centuries BC) and the Kingdom of Urartu (1000–600 BC) successively established their sovereignty over the Armenian Highland. Each of the aforementioned nations and tribes participated in the ethnogenesis of the Armenian people. A large cuneiform lapidary inscription found in Yerevan established that the modern capital of Armenia was founded in the summer of 782 BC by King Argishti I. Yerevan is the world's oldest city to have documented the exact date of its foundation.

In the next centuries, Armenia was in the Persian Empire's sphere of influence during the reign of Tiridates I, the founder of the Arsacid dynasty of Armenia, which itself was a branch of the eponymous Arsacid dynasty of Parthia. Throughout its history, the kingdom of Armenia enjoyed both periods of independence and periods of autonomy subject to contemporary empires. Its strategic location between two continents has subjected it to invasions by many peoples, including the Assyrians (under Ashurbanipal, at around 669–627 BC, the boundaries of the Assyrian Empire reached as far as Armenia & the Caucasus Mountains), Medes, Achaemenid Persians, Greeks, Parthians, Romans, Sassanid Persians, Byzantines, Arabs, Seljuks, Mongols, Ottomans, successive Iranian Safavids, Afsharids, and Qajars, and the Russians.


Who ruled the Assyrians between 669-627 BC?


After the Marzpanate period (428–636), Armenia emerged as the Emirate of Armenia, an autonomous principality within the Arabic Empire, reuniting Armenian lands previously taken by the Byzantine Empire as well. The principality was ruled by the Prince of Armenia, and recognized by the Caliph and the Byzantine Emperor. It was part of the administrative division/emirate Arminiya created by the Arabs, which also included parts of Georgia and Caucasian Albania, and had its center in the Armenian city, Dvin.
