ABSTRACT:
A translator for translating objects defined in an object-oriented programming environment to a relational database schema permits persistent storage of object instances as records in a relational database. Object instances are mapped to entity tables with object instances represented by entity records. Simple attributes are mapped to primitive typed attribute columns and class valued attributes are represented by foreign keys into entity attribute tables. Derived attributes are represented by joins of the parent and child entity records.
