Product design data model is established on the base of object oriented model ( oom ) foundation method and tree data structure theory , the paper has put forward the idea of currency data structure tree and design data structure tree seperate model foundation . the process model foundation method in which idefo and structure analyse are integrated is applied to define the concurrent design process model . combined with client / server network database manage system , the frame and implementation of concurrent design system based on product data management are discussed 本文在簡要介紹產(chǎn)品數(shù)據(jù)管理的含義、主要內(nèi)容及研究和應(yīng)用現(xiàn)狀后,提出了支持并行設(shè)計(jì)的產(chǎn)品數(shù)據(jù)管理系統(tǒng)的概念;應(yīng)用了面向?qū)ο蟮姆椒ê蜆錉顢?shù)據(jù)結(jié)構(gòu)理論,建立產(chǎn)品設(shè)計(jì)數(shù)據(jù)的樹狀結(jié)構(gòu)模型;提出了通用數(shù)據(jù)樹和設(shè)計(jì)數(shù)據(jù)樹分離建模的思想;引入了idefo和結(jié)構(gòu)化分析的過程建模方法,用以定義并行設(shè)計(jì)的過程模型;結(jié)合客戶/服務(wù)器結(jié)構(gòu)網(wǎng)絡(luò)數(shù)據(jù)管理系統(tǒng)的概念,給出了支持并行設(shè)計(jì)的產(chǎn)品數(shù)據(jù)管理系統(tǒng)的原型框架和具體實(shí)現(xiàn)方法。
