Yhpdm System Encoding And Map Document Marking Technology Research

Along with the rapid development of information industries and the computer networks, people need to share and transport various information through all kinds of computer platforms and hosts. The enterprise must solve the problem that how to transport various product data generated by soft each other and how to manage data information validly between Hetero-structure databases. In this case, we can handle these information and data by using PDM so that we can share the information and keep the data consistent during transportation.PDM is a kind of technology that manages all information and all product process about product. The coding management is used to define and create code, and the graphic document red-line is absolutely necessary tool for the graphic document management.After analyzing PDM system's function and structure,this paper designs and realizes the coding management and the graphic document red-line system based on three-ties distributed application.. Enterprise can define varied coding rules according to product characteristic and generate code automatically with the coding management., The graphic document red-line realizes the retrieve and query of information in database by using OLE ,it also offers all kinds of tools to red-lining fileso...
