The DBMS is expected to :
1 . Allow users to create new databases and specify their schemas ( logical structure of the data ) , using a specialized data - definition language.
2 . Give users the ability to query the data ( a “query" is a question about the data ) and modify the data , using an appropriate language , often called a query language or data - manipulation language.
3 . Support the storage of very large amounts of data - many terabytes or more - over a long period of time , allowing efficient access to the data for queries and database modifications.
The DBMS is also expected to:
4 . Enable durability , the recovery of the database in the face of failures , errors of many kinds , or intentional misuse .
5 . Control access to data from many users at once , without allowing unexpected interactions among users ( called isolation ) and without actions on the data to be performed partially but not completely ( called atomicity )
