Update Anomaly: We can not update attribute in a table because there may different values for the same attribute in same table. There are several advantages of DBMS, and they are as follows: - data can be retrieved easily and quickly, - easy to impose integrity constraints, - no redundancy, - easily to maintain ACID property of transaction - easily to update data.
