DOSS: A Storage System for Design Data

This report describes DOSS and its capabilities, some design decisions made within it and the associated tradeoffs. DOSS is a storage system designed to support CAD applications efficiently. We define composite objects, examine their ability to capture design data and outline our approach to distributed object naming. We believe our choice of the system/application interface is crucial for achieving acceptable performance in the CAD environment. We also describe our approach to associative search, change control and version management.
