Database Management Systems Database management systems (DBMS) are categorized according to the database model that they support. The type of software used for this is called a database management system (DBMS). The model determines the query languages available to access the database. Query languages determine how the data is retrieved, manipulated and then used to make business decisions. Other important issues that a DBMS addresses include managing performance, concurrency, integrity, and recovery from hardware failures.
