Using database management system or DBMS has several advantages over preparing and using a manual database:

First, a DMBS gives you the power to analyze and discover relationships about data. You can query the database, or ask specific questions, to determine if the information in your database meets specific conditions.

Second, you can create reports that can display the information from your database in a variety of formats. The relational database has the ability to combine data from more than one table. This allows you to create small, separate, easily managed tables with a minimum of duplication.
