Database Management System

 

  • A Database Management System is a collection of interrelated data and a set of programs to access to those data.
  • The collection of Data is referred as Database.
     
  • The primary goal of a Database Management System(DBMS) is to provide a way to store and retrieve database information that is both convenient and efficient.
Data are very important in any information system. So we must have a very good way of managing such data. The DBMS contain a query language that makes it possible to give quick and exact answers to adhoc queries. The DBMS helps to create an environment in which users have better access to data. Such access makes it possible for end users to respond more quickly and efficiently to changes in their environment.

DBMS helps to give an integrated view of the organization’s operations. Thus it becomes much easier to see how operations in one unit affect others. Data inconsistency is considerably reduced in a properly designed database. Database systems are designed to manage large volume of information. Data management involves both defining the structure for storage of information and providing mechanism for the manipulation of data. Also the database system must ensure the safety of the information stored.

The DBMS makes it possible to share the data in the database among multiple applications and users. DBMS serves as the intermediary between the database and the user by translating user request to the database and getting back exact responses to the user. Also the DBMS hides the internal complexities from the application programs that use the database.
