We describe an integration of Iris, an object-oriented database system, and AGIS, a solid modeler, into a single, unified environment for the management of both geometric and non-geometric data. Objects and operators of the modeler are accessible through OSQL, the database query language, in a completely transparent manner. This provides access to functionality of the modeler through a declarative, object-oriented language, and allows both geometric and non-geometric data to be manipulated easily and uniformly. To test the integration of the two systems, we developed an application program that managed three-dimensional part assemblies. Our experience in developing and using the application is: (1) the uniform and declarative OSQL interface greatly simplified application development; and (2) the ad hoc query capability of Iris proved to be very useful, as it allowed sophisticated users to interrogate the object base in ways unanticipated by the application developer, and to effectively extend the set of operators beyond those hard-wired in the application.
