A database management system is the software system that allows users to create, store and maintain a database and provides required result in form of report to users.
Benefits of DBMS over to file system:
Interface between database and users
A DBMS facilitates to end users to create, insert,view, modify and delete data in a database. The DBMS essentially serves as an interface between the database and end users or application programs, ensuring that data is consistently organized and remains easily accessible.
Controlling Data Redundancy:
In file-system the duplicated copies of the same data are created at many places. But in DBMS, all the data of an organization is integrated into a single database. For example, the student’ record file and the student’s result file contain several items that are identical. When they are converted into database, the data is integrated into a single database so that multiple copies of the same data are reduced to-single copy.
Users can share data simultaneously in DBMS.
Integrity constraints like primary key and foreign key can be applied to database so proper data stored in table and also uniqueness maintains.
