Which of the following statements is true concerning JDBC?

  • A.It is language independent.
  • B.It is similar in concept to ODBC.
  • C.It is useful for all object-oriented languages.
  • D.It consists of three main layers.

Answer: B

Correct answer: It is similar in concept to ODBC.

JDBC does for Java what ODBC does generally: a common call interface with a driver for each database, so the application code is written once and the driver deals with the vendor’s particulars. The differences follow from that - it is specific to Java rather than language independent, and so is not available to object-oriented languages in general.
