> # About DataDirect Spy™

> DataDirect Spy is a software component for tracking JDBC calls at runtime. It passes calls issued by an application to an underlying JDBC driver and logs detailed information about those calls. DataDirect Spy provides the following advantages:

> - Logging is JDBC 3.0-compliant, including support for the JDBC 2.0 Optional Package.
> - Logging is consistent, regardless of the JDBC driver used.
> - All parameters and function results for JDBC calls can be logged.
> - Logging can be enabled without changing the application.
> - DataDirect Spy can only be used with the SequeLink for JDBC Driver and the DataDirect Connect® for JDBC drivers.

> When you enable DataDirect Spy for a connection, you can customize DataDirect Spy logging for your needs by setting one or multiple options for DataDirect Spy. For example, you may want to direct logging to a local file on your machine.
