臺灣博碩士論文加值系統

近幾年來，Java技術於伺服端的應用—不論是企業資訊系統整合、資料庫應用、分散式計算、或者是網路應用程式開發等，皆逐漸展現其威力。其中，J2EE技術是一套針對開發全球資訊上網應用軟體的標準規格，已頗為大部分工業界所採用。然而對於開發此類系統的設計者而言，由於J2EE技術複雜且獨特而涵蓋面又廣，其在設計web-enable的應用程式時有其獨特性，因此本論文乃希望能夠針對J2EE平台提出為其量身打造的各式符號表示法，有效且更簡潔的描述J2EE平台上應用程式的設計。除了這些可以表達J2EE應用程式設計的文件符號外，我們更進一步提出一個可以作為設計J2EE應用程式參考的設計樣式，稱之為J2EE web application pattern。透過採用此樣式，J2EE的應用程式發展者，將可獲得單純化設計、改善系統效能、增進各元件重複使用性、與提昇維護能力等好處。本研究成果，使得大型web-enable應用程式的發展者，可快速地在J2EE平台上設計出架構合理、效能優異的應用軟體。

Undoubtedly, in the past five years Java technology has already gained a big success in Internet and enterprise solutions. In fact, this success has dramatically changed the way we did in server-side computing. J2EE, Java 2 plateform Enterprise Edition, has become the de-fecto platform for building large-scale web-enable enterprise applications. However, with the complexity of understanding J2EE, developers may not build a reasonable web-enable application by fully utilizing the advantages of the technology. Therefore, in this thesis we first try to propose a set of notations to describe the design of a web-enable application using J2EE technologies. With these notations, a J2EE application can be effectively and clearly documented. Secondly, we propose a design pattern called J2EE web application pattern for developing web-enable applications. By following the pattern, developers can quickly design a J2EE application with the benefits of better reusability, maintainability, and system performance.
