What Is DBMS?
Data is one of the most important assets of a company. It is very important to make
sure data is stored and maintained accurately and quickly. DBMS (Database
Management System) is a system that is used to store and manage data.
A DBMS is a set of programs that is used to store and manipulation data. Manipulation
of data include the following:

Adding new data, for example adding details of new student.

Deleting unwanted data, for example deleting the details of students who have
completed course.

Changing existing data, for example modifying the fee paid by the student.
A DBMS provides various functions like data security, data integrity, data sharing, data
concurrence, data independence, data recovery etc. However, all database
management systems that are now available in the market like Sybase, Oracle, and
MS-Access do not provide the same set of functions, though all are meant for data
management.
Database managements systems like Oracle, DB2 are more powerful and meant for
bigger companies. Whereas, database management systems like MS-Access are meant
for small companies. So one has to choose the DBMS depending upon the
requirement.
