# Relational Projects

Use a relational project for transactional persistence of Java objects to a conventional relational database (see "Building Relational Projects for a Relational Database") or to an object-relational database that supports data types specialized for object storage (see "Building Relational Projects for an Object-Relational Database"), both accessed using JDBC.

Note: If you are using TopLink Workbench, you must add your JDBC driver to the TopLink Workbench classpath. If you are using TopLink Workbench and direct to XML type mappings (see "Direct-to-XMLType Mapping"), you must add the Oracle Database `xdb.jar` file to the TopLink Workbench classpath. For more information, see "Configuring the TopLink Workbench Environment".

In a relational project, you can make full use of TopLink queries and expressions (see Understanding TopLink Queries).
