Answer :
a mechanism for managing databases (DBMS), programs that can evaluate data in accordance with the needs of the site, programs that give access to the system itself.
A database management system, sometimes known as a DBMS, is essentially just an electronic data storage system. The system gives users the option to perform a wide range of operations on it, either for maintaining the database structure itself or for changing the data in the database. Database management solutions are categorized using data structures or kinds (DBMSs). Mainframe sites commonly employ a hierarchical architecture when the data structure—rather than the data values—of the data required for an application is mainly static. A Bill of Material (BOM) database, for example, has many levels of components with subcomponents and a top level assembly part number.
