A DBMS (Database Management System) is a software application that helps create and manage databases. Popular DBMS are MySQL, Oracle, MongoDB, etc. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an application associated with the database.

Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an application associated with the database. Existing DBMSs provide various functions that allow management of a database and its data which can be classified into four main functional groups: Data definition – Creation, modification and removal of definitions that define the organization of the data. Update – Insertion, modification, and deletion of the actual data. Retrieval – Providing information in a form directly usable or for further processing by other applications. The retrieved data may be made available in a form basically the same as it is stored in the database or in a new form obtained by altering or combining existing data from the database. Administration – Registering and monitoring users, enforcing data security, monitoring performance, maintaining data integrity, dealing with concurrency control, and recovering information that has been corrupted by some event such as an unexpected system failure. A typical DBMS course covers these subjects: Data structures, file organizations, concepts and principles of DBMS’s, data analysis, database design, data modeling, database management, data & query optimization, and database implementation. Advanced DBMS topics include: relational data models; entity-relationship modeling, SQL, data normalization, and database design. Show less
