Oracle database - Oracle database The Oracle database is a relational database system from Oracle corporation extensively used in product and internet-based applications in different platforms. Oracle database was developed by Larry Ellison, along with friends and former coworkers Bob Miner and Ed Oates, who had started a consultancy called Software Development Laboratories (SDL). They called their finished product Oracle, after the code name of a CIA-funded project they had worked on at a previous employer, Ampex.

Java Database Connectivity - Java Database Connectivity Java Database Connectivity, or JDBC, is an API for the Java programming language that defines how a client may access a database. It provides methods for querying and updating data in a database. JDBC is oriented towards relational databases. The Java 2 Platform, Standard Edition includes the JDBC API together with an ODBC implementation of the API enabling connections to any relational database that supports ODBC. This driver is native code and not Java.

These drivers fall into one of the following types: Type 1 driver Type 2 driver Type 3.
Database management system - Database management system A database management system (DBMS) is a computer program (or more typically, a suite of them) designed to manage a database, a large set of structured data, and run operations on the data requested by numerous users. Typical examples of DBMS use include accounting, human resources and customer support systems. Originally found only in large companies with the computer hardware needed to support large data sets, DBMSs have more recently emerged as a fairly standard part of any company back office. DBMS's contrast with the more general concept of a database applications in that they are designed as the "engine" of a multi-user system. In order to fill this role, DBMSs are typically built around a private multitasking kernel with built-in networking support..
Database transaction - Database transaction A database transaction is a unit of interaction with a Database management system or similar system that is treated in a coherent and reliable way independent of other transactions. Ideally, a database system will guarantee all of the ACID properties for each transaction. In practice, these properties are often relaxed somewhat to provide better performance. In database products the ability to handle transactions allows the user to ensure that integrity of a database is maintained. A single transaction might require several queries, each reading and/or writing information in the database. When this happens it is usually important to be sure that the database is not left with only some of the queries carried out. For example, when doing a money transfer, if the money.
Database administrator - Database administrator (Database Administrator) A person who is responsible for the environmental aspects of a database. In general, these include: Recoverability Integrity Security Availability Performance Development and testing support The duties of a database administrator at a particular site vary, depending on the policies in place and the database management system’s (DBMS’s) capabilities for carrying them out. Before going on, we need to briefly define and describe “database.” A database is a collection of related information, accessed and managed by its DBMS. After experimenting with hierarchical and networked DBMSs during the 1970’s , the IT industry became dominated by relational DBMSs such as Oracle Server. A relational DBMS manages information about types of real-world things (entities) in the form of tables that represent the entities. A.
Relational database management system - Relational database management system A relational database management system is a database management system that is based on the relational model as introduced by Edgar F. Codd. Strictly speaking it should also satisfy Codd's 12 rules but in practice there is no DBMS that satisfies all these rules. In fact, most successful DBMSs (and the query language SQL) that are considered to be relational violate the relational model in several important ways. However, most database practitioners and researchers use the term in a loose way such that most databases that support SQL are also included. The first released RDBMS that was a relatively faithful implementation of the relational model was the Multics Relational Data Store, first sold in 1978. Others have been Berkeley Ingres QUEL and IBM.
Object-relational database - Object-relational database And Object-Relational database management systems (ORDBMS) are an evolutionary extension of relational DBMS products. The term is also sometimes used to describe external software products running over traditional DBMSs to provide similar features. These systems are more correctly referred to as object-relational mapping. Whereas RDBMS -- or SQL-DBMS -- products focused on the efficient management of data drawn from a limited set of data types (defined by the relevant language standards) an object-relational DBMS allows software developers to integrate their own types and the methods that apply to them into the DBMS. The goal of ORDBMS technology is to allow developers to raise the level of abstraction at which they view the problem domain. In an RDBMS, it would be fairly common to see SQL like.
Oracle machine - Oracle machine In complexity theory and computability theory, an oracle is a black box that computes a function in a single step. This could be a function solving an NP-complete problem such as the subset sum problem. It could even be an "uncomputable" (non-recursive) function like the halting problem.

The Turing machine can write on its own tape an input for the oracle, then tell the oracle to execute. In a single step, the oracle computes its function, erases its input, and writes its output to the tape. Sometimes the Turing.
Oracle Corporation - Oracle Corporation Oracle Corporation, one of the major companies developing database management systems and tools for database development, dates from 1977 and has offices in more than 145 countries around the world. Lawrence J. Ellison (Larry Ellison) has served as Oracle's CEO for several years. He also as of 2003 functions as chairman of the company.

Oracle BMW - Oracle BMW Oracle BWM is a sailboat racing syndicate, initially formed to compete in the 2003 America's Cup. The syndicate is backed primarily by Larry Ellison, who made his billions off of Oracle's database software. The team was created out of the ashes of Paul Cayard's AmericaOne syndicate (which lost the 2000 Louis Vuitton Cup to Prada in an epic battle) when Cayard sold the lion's share of his assets to Ellison's new Oracle syndicate. The syndicate got off to a rocky start with changes in the skipper position, going through Cayard, Chris Dickson and Peter Holmburg. Also, the St. Francis Yacht Club was unwilling to give Ellison the free hand he wanted in running the challenge for the 2003 America's Cup, so Ellison took his.
Oracle (disambiguation) - Oracle (disambiguation) Oracle could refer to any of these : Oracle - a person who makes predictions based on a claimed connection to the Gods. Oracle Corporation is a database software company. Oracle database is its popular database product. See Oracle machine for the "oracle" in theoretical computer science. The Internet Oracle is an attempt at collective humor that operates through email. "The Oracle" is the name of a character (played by Gloria Foster and Mary Alice) in the Matrix series. The Monmouth College Oracle was formerly the student newspaper of Monmouth College in Monmouth, Illinois. It was succeeded by the Monmouth College Courier. ORACLE was also a teletext service on ITV. It was replaced by Teletext..

JBuilder - JBuilder. There is even a free limited version for beginners of the Java language. JBuilder, with a few modifications, is used as the internal engine of Oracle's own JDeveloper for their database. JBuilder's main competitors are the products from IBM (Websphere), BEA Systems and Eclipse..
Informix - Informix The term Informix refers to a relational database, and for almost 20 years also referred to the company which developed it. The Informix DBMS developed from the pioneering Ingres system that also led to Sybase and SQL Server. For a time in the 1990s Informix was the second most popular database system, after Oracle. Success did not last very long, however, and by 2000 a series of management blunders had all but destroyed the company. In 2001 IBM purchased Informix in order to gain access to its existing market share and customer base. Long-term plans to merge Informix technology with DB2 have emerged, since the Informix Arrowhead project has now become the DB2 Arrowhead. IBM has also undertaken to support older versions.

Ingres - Ingres This article is about a relational database system. For the artist, see Jean Auguste Dominique Ingres. Ingres was an early relational database system, created as a research project at the University of California, Berkeley starting in the early 1970s and ending in the early 1980s. The code, like that from other projects at Berkeley, was available at minimal cost under a version of the BSD license. By the mid-1980s Ingres had spawned a number of commercial database applications, including Sybase, SQL Server, NonStop SQL, Informix and a number of others. A follow-on project started in the mid-1980s as Postgres, leading to the development of PostgreSQL, Illustra, and later versions of Informix. By any measure, Ingres is one of the most influential modern computer research projects. History Ingres In.
History of operating systems - you use the non-UNIX interfaces, unique to z/OS, your program is not easily portable on a non-z/OS operating system. To read more about z/OS, UNIX, LINUX and other OS on zSeries, go to http://www.ibm.com/servers/eserver/zseries/os/. Minicomputers and the rise of UNIX The UNIX operating system was developed at AT&T. Because it was essentially free in early editions, easily obtainable, and easily modified, it achieved wide acceptance. Later it was the choice starting point for developing operating systems for evolving minicomputers. Due to its earlier widespread use it exemplified the idea of a operating system that was conceptually the same across various hardware platforms. It still was owned by AT&T and that limited its use to groups or corporations who could afford to license it. Many early operating systems were collections of utilities.
HyperCard - Computer which runs only in Mac OS Classic. It most closely resembles a database application in concept, in that it stores information, but unlike traditional database systems HyperCard is very flexible and trivially easy to modify. In addition HyperCard includes a powerful and easy to use programming language to manipulate that data, one that is so easy to use that most HyperCard users used it as a programming system as opposed to a database. History HyperCard was created by Bill Atkinson and initially released in 1987, with the understanding that Atkinson would give HyperCard to Apple only if they promised to release it for free on all Macs. Originally called WildCard during its development, the name was changed to HyperCard before official release due to legal issues. The HyperCard application and.
Uniform Resource Locator - name such as www.wikipedia.org HTTP URLs can also contain additional elements, like a query string (placed after the path and separated from it by a question mark (?)) containing information from a HTML form with method=get, or a name tag (placed after the path and separated from it by a sharp mark (#)) giving the location within a hypertext page to display. FTP URLs often contain a port number. examples: http://www.wikipedia.org/w/wiki.phtml?title=Train&action=history http://www.wikipedia.org/wiki/Train#Model_railways URLs are one type of URI. The term URL is also used outside the context of the World Wide Web. Database servers specify URLs as a parameter to make connections to it. Similarly any Client-Server application following a particular protocol may specify a URL format as part of its communication process. Example of a database URL : jdbc:datadirect:oracle://myserver:1521;sid=testdb If.
Edgar F. Codd - contributions to the theory of relational databases. While working for IBM, he created the relational model for database management. He made other valuable contributions to Informatics, but the relational model, a very influential general theory of data management, remains his most memorable achievement. Edgar F. Codd was born at Portland, Dorset, in England. He studied mathematics and chemistry at Oxford University. He served as a pilot in the Royal Air Force during World War II. In 1948 he moved to New York to work for IBM as a mathematical programmer. In 1953, angered by Senator Joseph McCarthy, Codd moved to Ottawa. A decade later he returned to the USA and received his doctorate in computer science from the University of Michigan in Ann Arbor. Two years later he moved to San.
Escapade - a server-side scripting language that is designed to provide an easy interface to database contents. It is specifically designed to create dynamic web documents from this data. Escapade can be used to generate any kind of document - HTML, XML, text, and more. While server-side scripting is not a new concept, ESP is designed to enable programmers to have easy access to data in databases and display a formatted version of it in their web pages without having to resort to ASP or relatively complicated Perl or PHP scripts. Escapade is (say its developers!) simple, elegant, and extremely fast, compared to other SSSL's. Escapade was originally designed to fill the need for a simple server-side scripting product that ran on non-Windows platforms. As such, it currently runs in the UNIX and.
