A Database Realization Method to Product Information Model Based on STEP

摘要：

Product data exchange and interfacing betweendifferent CAD/CAM systems are very important to thedevelopment of concurrent integrated design. In thispaper, an integrated STEP-based productioninformation model for mechanical systems is presentedFirst, an architecture of this system is established usinga three-layer architecture (application, logic andphysical layers) recommended by STEP, and a newinformation model using database implementationapproach is defined using STEPs EXPRESS language.This model include GIM (General Information Model),SIM (Structure Information Model), SCM (ShapeConstruction Model), PFM (Physical Feature Model),and MIM (Management Information Model). Then, thedatabase implementation method to information modelis analyzed thoroughly, which include how to build datadictionary, how to transfer EXPRESS entity to basetable in relational database and how to access productdata in database. The information model and itsapplication can make heterogeneous CAD systemintegration more convenient.
