摘要

隨著資訊技術的不斷進步，帶動了企業對於軟體資源的大量需求，目前企業普遍面臨使用已久的系統功能或環境已不敷現在大環境之需求，面臨汰舊換新的狀況，如何開發新系統架構及整合舊有系統呢，為了解決此問題，近年來軟體業界推出服務導向架構(Service-Oriented Architecture, SOA)，SOA是一種應用程式架構的概念，將應用程式及資源以可重複使用的「服務」方式呈現，使用標準化的介面相互溝通，藉此提供更高彈性、更高效率、及資訊整合的IT環境。
本研究探討企業現況人力資源在服務導向架構下之應用狀況可行性，透過雛型系統建置，來驗證SOA 在人力資源管理應用的成效。在本文中以人力資源管理作業中的員工訓練教育流程做為雛型系統的需求來源，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。在本文中UML文件是之系統分析文件設計的主要工具，其中USE CASE 與活動圖主要描述需求模型的系統範圍與系統角色間的活動流程，而User Interface 、循序圖作為與使用者溝通作業畫面需求的工具。為快速實作物件模型，本文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。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。

Information technology has great improved today. It leads the enterprise demand more functionality for the strategy needs. But most of enterprise’s legacy systems need to replace it or upgrade to provide new information technology. Could enterprises integrate legacy system and new technology with drop old systems? The Service-Oriented Architecture (SOA) is a new concept for this question. SOA is an architectural style whose goal is to achieve loose coupling among interacting software agents. A service is a unit of work done by a service provider to achieve desired end results for a service consumer. Both provider and consumer are roles played by software agents on behalf of their owners. In SOA, the legacy system’s function could be wrapped to a service-oriented component. It could intergrate to new applications with standard interface.

This paper discusses the possibility of application SOA in human resource management by developing a prototype system. The employee training process is as the requirement of this system. It use UML as system analysis tools. The USE CASE is used for define the scope of the system. The activity diagram is used for describing activities in the training process. A model driven engineering tool is used in this study. It compiles the system model and objects into the real java code and deploy the system on J2EE platform. This study shows that SOA could easy and fastly integrate human resource management’s legacy system and new IT features.
