DBMS is a high-level query language because it is used for real work data stored in relational data model, it evaluate queries very efficiently. In this way, users can manage large amount of structured data by DBMS. Users don’t have to write low level language to realize some specific functions, don’t need to debug or testing the application functions, therefore DBMS reduces development time.In DBMS, the data model, which is called schema, for example relational, we can have entities and attributes
