Databases exist in various forms, the best known probably being the relational database. Databases are managed by a Database Management System (DBMS). Besides ensuring consistency of data and their processing (reading and writing), the DBMS controls roles and privileges of users (groups) and also offers a range of functions to perform various operations on the data. The file format is usually linked to the DBMS, but there are independent exchange formats too.
