Database Management System (DBMS)

Database Management System (DBMS)

A database management system (DBMS) is a software package designed to de me, manipulate, retrieve and manage data in a database. A DBMS generally manipulates the data itself, the data format, field names, record structure and file structure. It provides users and programmers with a systematic way to create, retrieve, update and manage data. It also defines rules to validate and manipulate this data. There are many dissimilar types of database management systems, ranging from little systems that run on personal computers to huge systems that run on mainframes. Some other DBMS examples include: MySQL, SQL Server, Oracle, dBASE, FoxPro etc.

A DBMS relieves users of framing programs for data maintenance. Fourth-generation query languages, such as SQL, are used along with the DBMS package to interact with a database. A database is the back-end of an application. A DBMS receives instruction from a database administrator (DBA) and accordingly instructs the system to make the necessary changes. The DBMS essentially serves as an interface between the database and end users or application programs, ensuring that data is consistently organized and remains easily accessible. These commands can be to load, retrieve or modify existing data from the system.
