# Building EIS Projects With Indexed or Mapped Records

Previous

Next

TopLink Workbench does not currently support non-XML EIS projects. You must create such an EIS project in Java.

Using Java, you can create an EIS project for transactional persistence of Java objects to a nonrelational data source accessed using a J2C adapter and any supported EIS record type including indexed, mapped, or XML records.

If you use XML records, the TopLink runtime performs XML data conversion based on one or more XML schemas. When you create an EIS project in Java, you configure mappings with respect to these schemas, but the TopLink runtime does not directly reference them.

You can base queries on any supported EIS interaction: `IndexedInteraction`, `MappedInteraction` (including `QueryStringInteraction`), or `XMLInteraction` (including `XQueryInteraction`). For more information, see "Using EIS Interactions".
