The Microsoft JET Database Engine, or simply JET, is a database engine that was distributed widely by Microsoft but is now deprecated. As such, finding information on programming JET databases is becoming more and more difficult. This book attempts to remedy that by presenting necessary information about JET for programmers and database administrators.

This book assumes that the reader already has familiarity with SQL and requires a reference specifically for the JET database engine. Readers unfamiliar with SQL should first refer to the more generic database book Structured Query Language.
