- Integrity-Promotes accuracy and consistency in data.
- Multi-User Access-Multiple users are given simultaneous access to data.
- Backup and Recovery-Avoids loss of data through proper backups.

Relational DBMS (RDBMS)
Data is stored in tables (relations). MySQL and Oracle are among the famous examples.
