Document Management System Yhedm Key Technology Research And Implementation,

Because of the rapid development of computer networking, and need to share various information with others, in modern enterprises, more and more methods have been implemented to manage the unbelievable amount of information. PDM is an excellent way to resolve all these problems. It's not only a technology to manage the product data and procedure, but also a thought to manage information about the enterprise and its products in the environment of computer and networking.During the whole producing procedure, the management of data and information must be under just-in-time control, every step of it must be feed-backed to user and the system.In this paper, it's demonstrated that how to design a 3-tiered distributed system with PowerBuilder and MS SQL SEVER 2000, the goal of this system is to manage all kinds of documents of some product, including DWG files generated by CAD-like software and DOC generated by Word application, or something like that.In this paper, it's also demonstrated the way to design the system of YHEDM, from the developing environment, the designing of the database tables, to the whole system architecture; and what's more, the designing and implementing of the deferent applications.This system is based on database, and is a distributed application system, which is made up of 3 programs, such as server, client and manger application. In client application, two ways are adapted to resolve the generation and printing of 6 kinds of tables, one is through Automation technology with Excel, the other is through CAD.Finally, the way to view paper and document is to use an avtiveX control, named AutoVue. This control is inserted into client application with OLE technology, by which user can view files of lots of formats, even including 3-D CAD files.
