The Development Of Web-based PDM System For Small & Medium Sized Enterprises

As an integrated platform for enterprises information, PDM has been applied to more and more enterprises. But, at present, most of the PDM systems adopt conventional C/S mode. Those systems based on this mode have such defaults as difficulty in installing or upgrading or maintaining software, weak adaptability to system, inconvenience to use, and hard to transplant, etc. Furthermore, the practical requirements of enterprises, that development of those PDM systems should move from level, at which throwing emphasis on management and share of data during designing period to enterprise level, at which we pay more attention to the whole procedure, that the system could integrate existing application systems adequately, and call for information of trans-regional product data, all these ask for re-building of PDM system.As Web technology forges ahead and buds out into popularity, the Web, with its open architecture, becomes an ideal platform in present application of computer. Under such circumstance, the PDM system should be based on Web platform. With the research of the project "the research of integrated EDMS based on Web", which is sponsored by Sichuan Province, this dissertation puts forward the total structure of PDM system based on Web for small & medium enterprises and the theory and implementing methodology of it. The key technologies are discussed in detail in this dissertation about this system development, which includes procedure interface, database, system security, the creating of Bill of Material, automationpick-up of title bar information, and so on. The system has these functions: project management, workflow management, engineering drawing management, check management, and so onThe developing language of this system is Delphi7.0, which is owned to Borland Corporation. The supporting database is Microsoft SQL Server2000. The system runs on Windows2000 or Windows98 operation system. It is based on object-oriented design method, and the system has some features: single application interface, easy to manage and maintain, favorable expandability and transplantation, and so on.
