File Management System In Database:-

A file (or file based) management System is a Collection of programs used for managing data stored in various files. Each program within a file management system is developed independently and it defines and manages its own data. in file management system records in One file are not related to the records in any other file. This approach leads to many problems which include data duplication in different files, data inconsistency, sharing of data and lack of flexibility in organizing and querying the data.

The accounts Department, for example, may change the commission rate of salesman but the Sales Department may fail to update its file. This will produce reports calculated with Out-of-data figures.

On the other hand,a database containing information about all the citizens of a country for National identity card (NC) may contain millions of record.
