Abstract

This paper presents a cooperative transaction model for shared engineering databases which provides a higher degree of concurrency and process parallelism in CAD. As opposed to traditional transaction models where intra-transaction results are isolated, the presented model allows exchanging and sharing of data and supports the integration of subresults into a common solution. The realization of the transaction system is based on concepts of active and object-oriented database systems.
