  8. The mps system requirements analysis and the design of database are completed with uml modeling technology, which inosculates the system ' s requirement analysis process and the component - based software development process and pave way for the abstract, development and assembly of components. then the thesis divides the business layer in the typical three - tier architecture into another three sublayers that are the data express layer, data access logic layer and business rule layer, and a framework that is more explicit and easier to develop and reuse is constructed. in this framework, the design strategy and method of components in diverse layers are given to complete their corresponding functions

    本文首先利用uml面向對象建模方法完成了mps系統的需求分析和數據庫的設計，使需求分析過程與開發過程更緊密地結合起來，為組件的抽取、開發與組裝奠定了基礎；然後將典型三層系統結構中的業務邏輯層分為業務實體層、數據訪問邏輯層和業務規則層，提出了一個更加清晰、易於開發和復用的總體框架結構，並設計了框架中不同組件的開發策略；最後利用com mts com +組件技術完成了基於本框架的mps系統中各層組件的開發、分散式事務處理及部署通信，調試了系統的運行，實現了系統的功能。
  9. As is stated above, this thesis did research on struts, spring and hibernate frameworks, and analysed each framework ’ s function in web application layer. an architecture is integrated with the three frameworks which is suitable for enterprise web application. the architecture hands business logic of struts to spring ; utilize beans configuration to manage the related classes ; manage objects ’ relation of between controller and data access object through spring and make data persistence by hibernate. this thesis made did deep analysis and research on coupling of integration between spring and struts and put forward a solution to loose coupling of integration
