SQLJ is an alternative to using JDBC for providing persistence to the J2EE application server platform. Because SQLJ is built, in part, on JDBC, it shares many of the same issues JDBC has with data conversion. For more information on the SQLJ interface, see the discussion of Part 0 for SQLJ. Also see the discussion of Using JDBC with Application Servers.
The following diagram is the same one used with the discussion of JDBC and application servers. It is the same because SQLJ sits on top of the JDBC interface.
Also, be sure to check out how SQLJ can be part of integrated J2EE Architecture Solutions.
Like JDBC, SQLJ will require data conversion in either the application server or in the applications. See SQLJ Data Conversion.

This is a guide for the savvy manager who wants to capitalize on the wave of change that is occurring with Web Services, service-oriented architecture, and—more recently—Cloud Computing. The changes wrought by these technologies will require both a basic grasp of the technologies and an effective way to deal with how these changes will affect the people who build and use the systems in our organizations. This book covers both issues. Managers at all levels of all organizations must be aware of both the changes that we are now seeing and ways to deal with issues created by those changes.
