摘要

近幾年因資訊科與網際網路傳輪技術的進步與網路普及已改變了商業市場競爭的型態，全球企業為了因應近幾年商業市場上激烈的競爭，企業實施結盟或協同商務的商業策略漸漸增加 ，因此使企業組織結構及商業活動複雜化，因此企業紛紛進行將企業組識內外的資訊系統進行整合，以提升企業對市場競爭的敏捷性，並提供更多樣與更快速的服務機制以提升企業的競爭能力。而傳統以企業內部資料或資訊為導向的IT架構已無法有效回應此商業競爭的環境。因此服務導向架構（Service-Orientation Architecture,SOA）的概念是由Gartner在1996年提出，採用SOA的方法可以讓企業更加的敏捷，並承諾能透過（Service）的重複使用減少應用程式發展和維護所需的成本 。企業服務匯流排（Enterprice Service Bus, ESB）在2002年被發表， ESB本質上是一個具有通訊基設施是以連接導向（Connectivity-Oriented）為主，其主要是在協助服務導向架構（Service-Orientation Architecture,SOA）主要負責管理並銜接SOA架構中各種應用服務，即服務元件與服務元間的派送及調度的排程以防止服務元件被呼叫時產生資源等待期。
本研究以IBM WebSphereESB系統展示，來驗證其是否達到服務導向架構(Service-Orientation Architecture,SOA)下企業服務匯流排（Enterprice Service Bus, ESB）的原理及原，則即服務的即時性、可重覆性、可在利用性、整合性、訊息的即時性。
本研究結果發現IBM WebSphere的軟體本身為封閉式的軟體，在非同平台的軟體與其整合時會有某些部分不相容的情形。因此本研究可提供後續研究者考慮到要整合非封式式的軟體時的參考。

In recent years of information technology and network transmission technology advances and network popular has changed the pattern of competition in the commercial market, To the last few years commercial market competition, Enterprise Alliance or collaborative commerce business strategy increases, therefore the organizational structure and business become complexity, so companies have to integrate enterprise information systems inside and outside the organizational, to improve enterprise agility to market competition, and to provide more variety and faster service mechanism to enhance the competitiveness of enterprises. traditional enterprise data or information oriented of IT infrastructure has been unable to effectively respond to the business environment.Therefore, service-oriented architecture (Service-Orientation Architecture, SOA) concept is proposed by the Gartner in 1996, using SOA approach enables enterprise more agile, and commitment through (Service) of the re-use to reduce application development and maintenance costs. Enterprise Service Bus (Enterprice Service Bus, ESB) was published in 2002, ESB is connection-oriented (Connectivity-Oriented) of the communications infrastructure, which its mainly in assistance service-oriented architecture (SOA) manage and link the various application services, the service components and services component of the delivery and scheduling of scheduling, to prevent the service component is calling and when resources waiting period.

In this study, using IBM WebSphereESB for system display, to verify whether the service-oriented architecture of the enterprise service bus principle and the principle that services can be real time,repetitive, reuse, integration, instant message.

This study found that IBM WebSphere Software itself is closed software, in Heterogeneous platform integration with some parts are not compatible. Therefore, this study may provide follow-up if the researchers to consider the integration of non-closed software for reference.
