"Object-Relational Mappings" | Mappings that transform certain object data member types to structured data source representations optimized for storage in specialized object-relational databases such as Oracle Database. Object-relational mappings let you map an object model into an object-relational data model. | Advanced |  |
"EIS Mappings" | Mappings that transform object data members to the EIS record format defined by the object's descriptor. | Advanced |  |
