The relational persistence framework of the J2EE Engine is called Open SQL for Java. It is a part of a comprehensive infrastructure that is designed to provide persistency for application development inside the J2EE Engine. Among the key features of the framework are:

·        Database independence

·        Efficiency

·        Maintainability

·        Orientation to standards

·        Close integration into the J2EE Engine

·        Enhanced performance by table buffers and statement pooling

The Open SQL for Java offers a set of programming models:

·        Open SQL/JDBC – this enables support for the JDBC standard used for dynamic queries to the database

·        Open SQL/SQLJ – this model is based on the ISO-standardized SQLJ and provides support for static SQL embedded in the Java code.

For a quick guide to working with the Open SQL for Java framework, see the Getting Started with Relational Persistence.
