摘要

企業的競爭力隨著資訊技術進步，以及企業資料的運用大部份都來自於系統資訊的蒐集，所以也相對的提高企業應用系統重要性，資訊的發達帶動了企業對於系統軟體的高需求，目前很多企業普遍面臨使用已久的系統功能或環境的改變導致原有系統的不敷使用，有些企業更面臨汰舊換新的狀況，所以企業需如何開發新系統架構及整合舊有系統，就變得是企業必須傷腦筋的一個大問題，所以這幾年來在軟體市場上嗅到企業所面臨的系統更換這類的問題，推出服務導向架構(Service-Oriented Architecture, SOA)，SOA是一種應用程式架構的概念，SOA更是一種藍圖，他可以將應用程式及資源以重複使用的「服務」方式呈現，使用標準化的介面相互溝通，因此提供更高彈性、更高效率、及資訊整合的IT環境。
本研究探討企業資源規劃系統(Enterprise Resource Planning, ERP)在服務導向架構下轉化成服務導向架構的企業資源規劃系統可行性，透過原有系統建置，運用SOA服務導向架構原理，來驗證SOA在企業資源規劃系統的成效。在本研究中以企業資源規劃系統的增加企業需求做為 SOA ERP 系統的需求來源，以UML作為模型描述工具，並以J2EE作為本系統之實作技術平台。在本研究中使用一個中介設計軟體(MDA TOOL)作為物件定義的工具，系統模型所需之各類物件一一定義為個別XML格式物件定義檔，透過MODEL COMPILER 的工具快速轉換為J2EE平台上的程式碼，並進行部署與測試，將企業需求在網頁上正確又快速的呈現。這樣的系統發展模式實踐了SOA的必要元素，快速、彈性地發展與整合企業內所需服務。

The competitiveness of enterprises with information technology advances and using the large majority of corporate data are collected from information in the system, so the relative importance of enterprise application systems, information developed by driving business system software for high-demand, are currently facing many enterprises use the long-awaited system functionality or environmental changes in the prevailing system of inadequate, some enterprises more faced bureaucratic trade-in status, so enterprises with a view to developing the new system architecture and integration of legacy systems, it becomes an enterprise must pose a big problem, so the past few years in the software market smell of system replaced this kind of problem, launch of service-oriented architecture (SOA) Architecture, Service-Oriented, SOA is an application schema concepts, SOA is a blueprint, he can add applications and resources to reuse of "services" to render, using standardized interfaces to communicate, it provides much more flexibility, higher efficiency, and information integration in the it environment.
This study examines enterprise resource planning system (ERP, Enterprise Resource Planning) in service-oriented architectures into service-oriented architecture of enterprise resource planning system feasibility, the establishment through the existing system, applying the principles of SOA, service-oriented architecture to verify SOA in enterprise resource planning systems. In this case, to enterprise resource planning system to increase enterprise requirements for SOA ERP system needs sources, UML as a model to describe the tools, and J2EE as this system of implementation technology platform. In this case, using an intermediary design software (MDA TOOL) as the object definition tools, system model for the class a is defined as an object of a particular XML format object definition rail, through MODEL COMPILER tools fast conversion to J2EE platform program code, and deploying and testing, you will need on a Web page quickly and correctly. Such a system development model practice a necessary element of SOA, with fast, flexible development and integration of the services within the enterprise.
