Database management is the process of organizing, storing, and managing a database in a way that allows it to be accessed and modified efficiently. A database management system (DBMS) is a software application that is used to create, manage, and maintain a database.
Features of DBMS
The main features of a Database management system (DBMS) are:
- Data storage and organization: The DBMS stores and organizes data in a structured way, allowing it to be accessed and modified efficiently.
- Data security: The DBMS provides various security measures to protect the database from unauthorized access, tampering, and data loss.
- Data integrity: The DBMS ensures that the data in the database is accurate, consistent, and complete, by applying constraints and rules to the data.
- Data manipulation: The DBMS allows users to add, update, delete, and retrieve data from the database using various commands and queries.
- Data access: The DBMS provides various interfaces and tools for users to access and work with the data in the database.
- Data administration: The DBMS provides various tools and utilities for database administrators to manage and maintain the database, such as backup and recovery, performance tuning, and user management.
- Data sharing: The DBMS allows multiple users to access and work with the data in the database simultaneously, in a controlled and coordinated way.
