Implementing OOSQL on Relational Database

The implementation of OOSQL, an object-oriented database language, on a relational database is described in this paper. Because of the difference between object-oriented data model and relational data model, the problems considered are how to use the relational database itself, and how to represent objects and the semantic associations between them with data dictionary management, the transformation from DDL and DML of OOSQL to SQL is also described.
