	Relational database management system - Wikipedia, the free encyclopedia
		A relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as introduced by Edgar F. Codd.
		The first systems that were relatively faithful implementations of the relational model were from the IBM UK Scientific Centre at Peterlee; IS1 (1970–1972) and its followon PRTV (1973–1979).
		Database Debunkings - Critical point of view that argues that it is important that the predicate relational should be reserved for those database systems that are fully faithful to the relational model.

	Database management system - Wikipedia, the free encyclopedia
		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 clients.
		As computers grew in capability, this tradeoff became increasingly unnecessary and a number of general-purpose database systems emerged; by the mid-1960s there were a number of such systems in commercial use.
		When the database was first opened, the program was handed back a link to the first record in the database, which also contained pointers to other pieces of data.

	RFC 1697 (rfc1697) - Relational Database Management System (RDBMS) Managem
		Databases are collections of interrelated data organized according to a schema to serve one or more applications.
		A database is, for purposes of this MIB, a collection of tables whose organization is based on the relational model.
		Relational Database Management System (RDBMS) A collection of integrated services which support database management and together support and control the creation, use and maintenance of relational databases.

	Why Aren't You Using An Object Oriented Database Management System?
		Object oriented programming concepts such as encapsulation, polymorphism and inheritance are enforced as well as database management concepts such as the ACID properties (Atomicity, Consistency, Isolation and Durability) which lead to system integrity, support for an ad hoc query language and secondary storage management systems which allow for managing very large amounts of data.
		Database operations typically involve obtaining a database root from the the OODBMS which is usually a data structure like a graph, vector, hash table, or set and traversing it to obtain objects to create, update or delete from the database.
		In a relational database this has to be done either by having one huge table with lots of null fields or via a number of smaller, normalized tables which are linked via foreign keys.

		A relational database allows the definition of data structures, storage and retrieval operations and integrity constraints.
		In such a database the data and relations between them are organised in tables.
		Because these relationships are only specified at retreival time, relational databases are classed as dynamic database management system.

		Short for relational database management system and pronounced as separate letters, a type of database management system (DBMS) that stores data in the form of related tables.
		Relational databases are powerful because they require few assumptions about how data is related or how it will be extracted from the database.
		An important feature of relational systems is that a single database can be spread across several tables.

	Architecture of Oracle Database Management System
		Oracle is a Relational Database Management System (RDBMS), which uses Relational Data Model to store its database and SQL (commonly abbreviated as Structured Query Language) to process the stored data.
		It is the Oracle instance, which manages all database activities, such as transaction processing, database recovery, form generation, and so on.
		If the last database shutdown was not clean, SMON automatically rolls forward the operations that were complete but could not be installed in the database, and rolls back unfinished transactions.

	15 Seconds : Introduction to Relational Databases - Part 1: Theoretical Foundation
		The concept of relational databases was first described by Edgar Frank Codd (almost exclusively referenced as E. Codd in technical literature) in the IBM research report RJ599, dated August 19th, 1969.
		The database description is represented at the logical level in the same way as ordinary data, so authorized users can apply the same relational language to its interrogation as they apply to regular data.
		If a relational system has or supports a low-level (single-record-at-a-time) language, that low-level language cannot be used to subvert or bypass the integrity rules or constraints expressed in the higher-level (multiple-records-at-a-time) relational language.

	Define database management system - a definition from Whatis.com - see also: DBMS (Site not responding. Last check: 2007-10-08)
		A database management system (DBMS), sometimes just called a database manager, is a program that lets one or more computer users create and access data in a database.
		The DBMS manages user requests (and requests from other programs) so that users and other programs are free from having to understand where the data is physically located on storage media and, in a multi-user system, who else may also be accessing the data.
		A DBMS can be thought of as a file manager that manages data in databases rather than files in file systems.

		Most commercial RDBMS's use the Structured Query Language (SQL) to access the database, although SQL was invented after the development of the relational model and is not necessary for its use.
		Despite repeated challenges by competing technologies, as well as the claim by some experts that no current RDBMS has fully implemented relational principles, the majority of new corporate databases are still being created and managed with an RDBMS.
