1、一.正向工程與逆向工程說明在前面幾篇里介紹了幾個(gè)PowerDesigner的常用模型，參考：PowerDesigner概念數(shù)據(jù)模型(CDM)說明http://blog.csdn.net/tianlesoftware/article/details/6871179?PowerDesigner物理數(shù)據(jù)模型（PDM）說明http://blog.csdn.net/tianlesoftware/article/details/6874067?PowerDesigner面向?qū)ο竽Ｐ停∣OM）說明http://blog.csdn.net/tianlesoftware/art
2、icle/details/6879229?PowerDesigner業(yè)務(wù)處理模型(BPM)說明http://blog.csdn.net/tianlesoftware/article/details/6882109?PowerDesigner企業(yè)架構(gòu)模型(EAM)說明http://blog.csdn.net/tianlesoftware/article/details/6883772?正向工程和逆向工程就是上面幾個(gè)模型相互之間轉(zhuǎn)換的過程。?正向工程：????CDM—>PDMPDM—>DatabasePDM—>OOM?從CDM到PDM也是軟件工程中推薦的一種方法，
3、不過在實(shí)際的項(xiàng)目中，很少有公司會(huì)按照這個(gè)流程來走，甚至連E-R圖都不畫，直接上來就建表。?逆向工程：(1)????從處理語言（ProcessLanguage）逆向生成業(yè)務(wù)處理模型（BPM）(2)????從對(duì)象語言（ObjectLanguage）逆向生成面向?qū)ο竽Ｐ停∣OM）(3)????從數(shù)據(jù)庫（Database）或數(shù)據(jù)庫腳本逆向生成物理數(shù)據(jù)模型（PDM）(4)????從XML定義（XMLDifinition）逆向生成XML模型?二.示例在這里演示2個(gè)例子:（1）???CDM-->PDM-->Database.（2）???Database-->PDM-->CD
4、M?2.1正向工程：CDM–>PDM–>Database示例?PD自帶的示例CDM：locatedintheTomb,DongShenJiabang,deferthenextdayfocusedontheassassination.Linping,Zhejiang,1ofwhichliquorwinemasters(WuzhensaidinformationisCarpenter),whogotAfewbayonets,duetomissedfatal,whennightcame?我們將這個(gè)CDM轉(zhuǎn)換稱PDM:?Tools-->GeneratePhysical
