DBMS
Database Management System
The part of a Database program that maintains the organization of the database as distincet from the part that carries out input/output and searching through the Records. An efficient management system will for example organise the data to take up the least amount of space possible on the disk, allow space vacated by deleting records to be reused and allow data records to refer to other records.
This prevents duplication of records and of computing activity and ensures for example that when an item such as a customer name is deleted from a list the account number corresponding to that name will also be deleted and the name will be deleted from all actions such as mailing lists. the most important objective of a dBMS is to ensure that data is recorded only once and used by all data hadling programs.
