Enhanced Classes and Managed Fields

  • David Ezzio

Abstract

The application programmer designs and codes the application data classes. The JDO implementation provides an enhancer tool to modify the application data classes. The modifications made during enhancement allow JDO and the application data objects to interact with each other. The JDO metadata, which is contained in an XML file, identifies the application data classes and describes their managed fields.
