Advantages of Database management system

Let us summarize the advantages.

Reduction of Redundancy: This is perhaps the most important advantage of using DBMS. Redundancy is the problem of storing the similar data item in more one place.  Redundancy makes several problems like requiring extra storage space, entering similar data more than once during data insertion, and deleting data from more than one place during deletion. Anomalies may happen in the database if insertion, deletion etc are not done properly.

Sharing of Data: In a paper-based record keeping, data cannot be shared between many users. But in computerized DBMS, lots of users can share the similar database if they are connected via a network.

 Data Integrity: We can handle data integrity by specifying integrity constrains, which are rules and restrictions about what type of data may be entered or manipulated within the database. This enhances the reliability of the database as it can be guaranteed that no wrong data can exist within the database at any point of time.

 Data security: We can restrict certain people from accessing the database or permit them to see certain portion of the database whereas blocking sensitive information. This is not possible very simply in a paper-based record keeping.
