Abstract

At MCC we have built a prototype object-oriented database system, called ORION to support applications from the CAD/CAM, AI, and OIS domains. Advanced functions supported in ORION include versions, change notification, composite objects, dynamic schema evolution, and multimedia data. The versions and change notification features were based on the model we developed earlier in [CHOU86]. In this paper, we show how we have integrated our model of versions and change notification into the ORION object-oriented data model, and also provide an insight into system overhead that versions and change notification incur.
