A simple yet powerful application programming interface for an object-oriented database system

This paper presents the application programming interface EQL-C used in the objectoriented database system InORM, which is based on a relation-object model. This interface takes a procedural approach and allows the statements of the InORM database language EQL to be embedded in C programs. As this Interface is simple to use, it shows its power by supporting object-oriented computing in an application program. Persistent objects are accessed and manipulated in much the same way as volatile objects.
