Research on Technology of Database for the Complex Assembly System

Database technology is the key technology to ensure assembly control data validity, completeness, consistency, security in the complex assembly system. A database model supporting complex assembly system was presented based on the requirement analysis of complex assembly system in data storage and extraction. The embedded database was used to storage the share visualization data for portable devices. The spatial database was built to storage the dynamic assemble process message (such as parts, frocks and assemble environment spatial position provided by Indoor GPS system). The distributed database systems supporting static model data and dynamic assembly process data storage constitute the data framework of complex assembly system
