A DBMS query language is designed to

  • A.Support end users who use English-like commands
  • B.Support in the development of complex applications software
  • C.Specify the structure of a database.
  • D.All of the above.

Answer: D

Correct answer: All of the above.

A query language covers all three: ad hoc questions in near-English for end users; the data manipulation that application code is built on; and, through its data definition part, the structure of the database itself. SQL is the obvious example - SELECT, INSERT and CREATE TABLE all belong to it.
