DBMS is a program that allows users to define, manipulate, and process data in a database to produce meaningful information. There are many types of DBMS ranging from small personal computer systems to large mainframe systems. DBMS provides advantages like preventing data redundancy, easy access to data, rule enforcement, security, sharing of large data volumes, time savings, and less storage space compared to manual file management. DBMS has wide applications in fields like banking, airlines, universities, retail, telecom, finance, manufacturing, and human resources.

6. Application of DBMSs in various fields There are many different types of DBMSs, ranging from small systems that run on personal computers to huge systems that run on mainframes. Database are applied in wide no. of applications. Following are some of the examples :- · Banking: For customer information, accounts, loans & other banking transactions · Airlines: For reservation & schedule information · Universities: For student information, course registration,grades etc. · Credit card transaction: For purchase of credit cards & generation of monthly statements.
