ORION is a prototype object-oriented database system built in the Advanced Computer Technology (ACT) Program at MCC. It is intended to support the data management needs of applications in such domains as computer-aided design, artificial intelligence, and office information systems. The paper describes features of ORION which have been implemented specifically to support CAD environments. These include dynamic schema evolution, version control and change notification, and transaction management.
