As the cost of data redundancy fell, it became feasible to store data in tables. This eliminated much data storage and provided much more flexible data access. Most DBMS databases today are

Advantages of DBMS Ø Redundancy is controlled. Ø Unauthorised access is restricted. Ø Data redundancy inconsistency. Ø Difficult in accessing data. Ø Data isolation.

Any such redundancy should be carefully controlled and the DBMS should be aware of it. Data Consistency Reduced data redundancy leads to better data consistency.
