An ODBC data structure that identifies a database and the DBMS that processes it is called a(n):

  • A.data source.
  • B.data structure diagram.
  • C.driver.
  • D.API.

Answer: A

Correct answer: data source.

A data source is the ODBC data structure that names both the database and the DBMS that processes it, together with whatever else is needed to reach it. It is what an application connects to by name, and the indirection is the point: change which database the name refers to and the application follows without being recompiled.
