1.9

List five responsibilities of a database-management system. For each responsibility, explain the problems that would arise if the responsibility were not discharged.

1. Security - Since DBMS have the concept of a ROLE (user) it easier for setting access managmenent.

2. Needs to offer atomicity when needed - If atomicity is not provided, inconsistency will be inevitable.

3. Needs to offer a simple and efficient way to query data

4. Needs to offer durability i.e. once an update or an insert has happened it must be persisted.

5. A DBMS needs to offer a way for protection against concurrent-access anomalies.
