7. Increased programmer productivity:-
Database data is separated from programs so Programmer greatly solves the problem.


8. Data integrity-
Data integrity means that the data contained in the database is both accurate and consistent. Centralized control can also ensure that adequate checks are incorporated in the DBMS to provided data integrity.

Data values being entered for storage could be checked to ensure that they tall within a specified range and are of the correct format. Another integrity 'check that should be incorporated in the database is to ensure (hat if there is a reference to certain object, then that object must exist.
