Part XII

EIS Mappings

TopLink enterprise information system (EIS) mappings provide support for accessing legacy data sources and enterprise applications through J2EE Connector architecture (J2C) adapter. TopLink EIS mappings use the J2C Common Client Interface (CCI) to access the EIS through its resource adapter. This provides the ability to directly map from an existing Java object model to any transactional data source, such as mainframes with flat file/hierarchical data. An EIS mapping transforms object data members to the EIS record format defined by the object's descriptor.
