In file based approach you need to maintain distinct files of every department where as in DBMS the whole data is located at a single place. It means anyone can access the data anywhere if have the required privileges.

The  file based suffers from redundant data and inconsistent data also it has poor data integrity. It has no Primary key and multipart fields. The Relational Database has none of these problems
