Uml Analysis And Modeling Of Pdm System Based On B / S Structure

PDM is a frame of integrated function.its effect is to carry out data shareing and flow controlling.The development about technology of Object Oriented,accelerates the function's advancement of PDM.Meanwhile,its function is requied higher and higher,too.But the traditional mode of software development does not work well in improving the quality of PDM,which is due to the stronger integration,modification and secondary development to a great extent.This paper is brought out by PDM's technology,then its development trend and function requirement is simply analyzed.Based on the character of PDM and the deficiency of traditional development mode,this paper advises to adopt the modeling technology—UML.UML is flexible modeling mechod of Object Oriented,its convenient usage,modeling flow's description,system's analysis and design are suit to PDM's fuction development.So PDM based on B/S system's structure is modeled after UML's character and modeling process analyzed.By the character of PDM and UML,three aspects are implemented.First,by the extended character of UML,the element of Web is defined,besides,used in the flow process of Examining and Approving. Second,RUP is stick to iterative software development of PDM.In the whole process,the function implement process of BOM in Product Structure serves as a example,from requirment analyse to code's design and function mode's modification,the strongpoint of UML's description about process and flow experiences more,the same to the favorableness about normative PDM's development process.The last,in allusion to the requirement of PDM's integration and secondary development,the module diagrams design function module's integration and data's intercommunication visually and intuitionisticly,which recurs to the process of project flow's subsection to workflow and workflow's integration to project flow.
