Designing And Developing On Engineering Drawing Information Management System

The growth speed of Chinese small and medium-sized manufacturing is great faster than the others of the world and this rapid growth has exposed the problem of the lag on the management. The manufacturing face a fact that the design department must deal with their real problems in one aspect, on the other side, other departments' information flow lag behind, although they make sure of the developing trend of information. The design department must concentrate on improving design efficiency and quality. Most important issue is how to reoccupy their mature design experiences and successful cases. The engineering drawing information management system has given a low-cost and integrated way on solving the problem of the small and medium-sized manufacturing.The primary work and study conclusion are as following:(1) Synthetically analyzes the actuality and the growing trend of the engineering drawing information management system. And combining the characters of small and medium-sized manufacturing, the dissertation offers a right way on designing and managing.(2) Introduces the presently fashionable technology on database and the system framework. Contrastively analyzing the character of framework C/S and B/S and the applying area of database SQL and others, the dissertation finally decides three layers C/S system framework with ADO: one side is service, another is client, and they are connected by ADO. Additionally, select VC++ as the developing tool and SQL as the database supply.(3) Finishes the whole designing and some basic functions. For example: uploading papers, downloading papers, browsing papers and looking up papers etc. By the way, the dissertation also designs the instant message function. With this function, the dissertation can solve the problem on communicating and cooperating. Besides, according to the factual requirement, the dissertation designs a beautiful, applied and easily operated user interface.The engineering drawing information management system has been tested on our LAN. It works well. The conclusion confirm the upward functions has came true and validate the designing method is feasible.In the end, the dissertation summarizes the deficiency of the system and gives some advices on the further studying.
