Abstract
An object oriented system for accessing an external relational database from within the object oriented system. The system creates an object and fills it with data values retrieved from the database. References from the object to other objects include pointers to preexisting objects or pointers to placeholder objects. Later retrieves fill in the placeholder objects, eliminating the need to reset the pointers. Caching, utilizing static data and static functions, is performed by each class of objects. Sub-objects are used to create different logical views of data from the database, and query access to the database is provided by a query engine which builds query language statements on demand.
