Concurrency Control in Computer Aided Cooperative Design System

Graphical Abstract

Abstract

Abstract

An approach to manage object data in graphic database is presented. Some key techniques such as nested transaction, transaction submitting, precautionary locking, and conflict resolving are discussed. In addition, the model of optimistic concurrency control and the process flow of transaction are described.
