> This book contains the following information:

> Part 1: Developing ODBC Applications

> - "Using the ODBC Client" provides information about using ODBC applications with the SequeLink Client for ODBC.
> - "Developing ODBC Applications" provides information about developing ODBC applications for SequeLink environments.

> Part 2: Developing ADO Applications

> - "Using the ADO Client" provides information about using ADO applications with the SequeLink Client for ADO.
> - "Developing ADO Applications" provides information about developing ADO applications for SequeLink environments.

> Part 3: Developing JDBC Applications

> - "Using the JDBC Client" provides information about using JDBC applications with the SequeLink Client for JDBC.
> - "Using DataDirect Test™" introduces DataDirect Test for JDBC, a development software component that allows you to test and learn the JDBC API. It also contains a tutorial that takes you through a working example of its use.
> - "Tracking JDBC Calls" introduces DataDirect Spy for JDBC, a development software component that allows you to track JDBC calls, and describes how to use it.
