Solution

The characteristics of a Database Management System (DBMS) are:

  1. Provides Security: A DBMS provides a framework for better enforcement of data privacy and security policies.

  2. Provides Backup and Recovery Facility: A DBMS contains important features like providing backup and recovery services. If a system crashes, a DBMS can recover the lost data.

  3. Removes Redundancy: DBMS can avoid redundancy (i.e., duplication) of data, which means it can save storage and also ensures consistency of data.

However, the following are not characteristics of a DBMS:

  1. It's Cheaper: This is not necessarily true. The cost of a DBMS can vary greatly depending on its complexity, functionality, and the licensing model.

  2. Does Not Support Multi-User Access: This is incorrect. One of the main advantages of a DBMS is that it allows multiple users to access data simultaneously.
