Database Management System is a system that provides an efficient way of storage, retrieval and modification of data. They are designed for the management of large volumes of data that most business activities deal with. A database is a systematic collection of interrelated data which can be shared and concurrently accessible. The safety and security of the stored data is ensured through database system. . Database systems can be centralized or distributed. In centralized systems, the entire data is stored at a single site; while in distributed systems, database is stored on various computers.

The advantages of database management systems are many. Database Management system ensures security of access to the data. In traditional system files can be easily accessible and are thus not secure. DBMS helps in recovering data at time of system crashes. DBMS controls repetition of data and inconsistency among them. While in traditional file system, same data can be present in two or more files. In DBMS, different users can share the same data and even access it concurrently. Also, business rules can be enforced in database management system so that invalid entry of data can be prevented.Thus, we see that there is lack of flexibility in traditional file keeping system and they are not secure for business activities. Databases are used in all real life software projects. Therefore, a more secure and efficient way to store and manipulate the database is required, which is possible through database management system.
