DBMS is short for Database Management System. This refers to a collection of applications that facilitate the extraction, modification and storage of data within a database.
The database management system acts as the interface between end users and the database itself, thus making sure data is constantly organized and accessible by other applications and users. A DBMS is made up of three major components, the database schema that is responsible for defining the logical structure of the database, the database engine that facilitates data access and the data itself. There are several types of database management systems, from small ones that run on PCs to large ones than run on data servers. Common examples include; Microsoft Access, MySQL and Oracle.
