Feature Of Database Management System

Salient Features of DBMS

Salient features of a database management system include database engine, data dictionary, query processor, report writer, forms generator, application generator communication, integration, and security

• Database Engine

The database engine is the heart of DBMS. I stores, retrieves, and updates the data Other components of database system rely on the database engine for their functioning

• Data Dictionary

The data dictionary holds definitions of all data items
stored in a database. It describes the data type of each data item e DBMS to keep track of the data.

• Communication and Integration

These are used to import and export data with different databases running on different computers

• Security and Other Utilities
