Database Management Systems
Next: Purpose of Database
A database management system (DBMS), or simply a database system
(DBS), consists of
- A collection of interrelated and persistent data (usually referred
to as the database (DB)).
- A set of application programs used to access, update and manage that data
(which form the data management system (MS)).
The goal of a DBMS is to provide an environment that is both
convenient and efficient to use in
- Retrieving information from the database.
- Storing information into the database.
Databases are usually designed to manage large bodies of information.
- Definition of structures for information storage (data modeling).
- Provision of mechanisms for the manipulation of information (file
and systems structure, query processing).
- Providing for the safety of information in the database
(crash recovery and security).
- Concurrency control if the system is shared by users.
