database management system is a software tool that makes it possible to organize data in a database. It is often referred to by its acronym, DBMS. The functions of a DBMS include concurrency, security, backup and recovery, integrity and data descriptions. 

Organizations use large amounts of data. A database management system (DBMS) is a software tool that makes it possible to organize data in a database.

The standard acronym for database management system is DBMS, so you will often see this instead of the full name. The ultimate purpose of a database management system is to store and transform data into information to support making decisions.

A DBMS consists of the following three elements:

  • The physical database: the collection of files that contain the data
  • The database engine: the software that makes it possible to access and modify the contents of the database
  • The database scheme: the specification of the logical structure of the data stored in the database
