Development Of Engineering Graphics Library Management System Based On OOP And Design Pattern

Nowadays, CAD application has been popularized in the enterprises insurvey and design industry, however, network computer management applicationis just at beginning. First, though the enterprises in survey and design industry hasaccumulated plenty engineering graphics, they are not efficiently managed;second,with China's entry into WTO, survey and design market has to be opened within 5years, so the corporate image, management level and competition ability must beimproved by using modern information system. Basing on concept and techniqueof current software engineering, making use of object oriented programming anddesign pattern, and according to the needs of the survey and design industry in ourcountry, this paper aims to develop a practical advanced engineering graphicslibrary management system with intelligence, inheritance and redevelopmentability.This paper mainly includes:First, the present condition and the development trend of engineeringgraphics library management system in survey and design industry aresynthetically analyzed;the engineering graphics library management systemsuitable for project design combining with the characteristics of enterprises is putforward.Second, this paper studies development course and their respectivecharacteristics of object oriented programming and design pattern in detail,introduces the its architecture, design and development in net briefly.Third, a C/S and B/S self-adaptive distributed architecture by theimprovement of traditional system architecture-Client/Server is put forward andrealized.Finally, we carry out a mid-scale and mid-complexity "Engineering graphicsLibrary Management System" by the directing of the theories mentioned above.The total work involves 400,000 lines program.
