Which of the following statements is a true statement concerning the open database connectivity standard (ODBC)?

  • A.Each vendor desiring to be ODBC-complaint provides an ODBC driver.
  • B.Requires certain criteria to be met in order to establish an ODBC connection.
  • C.Provides a programming interface that provides a common language for application programs to access and process SQL databases independent of the RDBMS accessed.
  • D.All of the above.

Answer: D

Correct answer: All of the above.

All three describe ODBC correctly. It defines a common programming interface so that an application can issue SQL without knowing which database it will reach; each vendor supplies a driver to make its product conform; and a connection requires the driver, the data source and the credentials to be in place before it can be established.
