  Database management system - Wikipedia
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.
Databases have been in use since the earliest days of electronic computing, but the vast majority of these were custom programs written to access custom databases.
Database design[?] is the process of deciding how to organize this data into record types and how the record types will relate to each other.

 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.
Thus applications that use RDBMS systems usually have an Entity Relationship diagram to model the static parts of the system and a seperate model for the operations and behaviors of entities in the application.

 Trusted Database Management System Interpretation   (Site not responding. Last check: 2007-09-23)
Demonstrating that the candidate system meets the TCSEC requirements (as they apply to the target evaluation class) requires that both A and B be evaluated with respect to the local requirements of the target class and that the composite TCB be evaluated for global requirements.
For database management systems, the objects that store the base data of the database (e.g., files, records, relations, and tuples), as well as those objects that store the metadata (e.g., directories, indices, schemas, data dictionaries, discretionary authorization tables, recovery logs, and transaction logs), must be labeled.
Where a database system builds on an underlying trusted operating system, for example, the set of candidate subjects for the two TCB subsets includes both the active entities created by the operating system and those active entities created by the trusted portion of the DBMS.

In 1968, the [1] University of Michigan began development of the Micro relational database management system.
The first "quickie" version was ready in 1974/5, and work then started on multi-table systems in which the data could be broken down so that all of the data for a record (much of which is often optional) did not have to be stored in a single large "chunk".

Note that as I keep the discussion to database models that are in significant current use; this is not meant to be a comprehensive survey of DBMS methodologies through history since some significant models, such as network databases, have been omitted because of a lack of modern tools and practice.
The problem with hierarchical databases is that they have a way of accumulating redundant data (which was one of the main claims of relational databases in their battle to wrest dominance from hierarchical databases in the '70s).
