網路服務(Web Services, WS)是一項新且有潛力的技術，它利用網路便利性的優勢，提供一個比傳統更簡單的溝通模式。網路服務讓流程間的整合更容易，此外，UDDI(Universal Description, Discovery, and Integration；統一描述、發現和整合)的仲介和搜尋功能，能幫助使用者搜尋所需求的服務，並可連結或整合這些服務。網路服務技術中的UDDI結構是使用XML Schema的型態來表示，它能在不同平台間做溝通，為不同平台的系統提供了整合的環境，使得系統整合更加容易。 傳統售票系統所遭遇的問題在於其系統難以擴充、當交易量大時，主機難以負荷、以及交易流程繁雜等。而透過網路服務的建置，可提升流程管理、再利用性、擴展性以及系統整合的優勢。本文即是利用網路服務的這些特性，發展出一套以網路服務為基礎的線上售票系統(WS-Based Online Ticketing System, WSOTS)，用來改善傳統售票系統的缺點。 Web Service (WS) is a new and promising technology. It uses the convenience of the network to offer a communication pattern. The WS technology also simplifies the process of integration. In addition, UDDI (Universal Description, Discovery, and Integration) has the function of agency and search, it not only helps users reducing search time for finding the expected services but also integrates and contacts with services. The UDDI structure is based on XML Schema, it can achieve communication between the different platforms. UDDI provides an integrated environment to make the integration of system easily. The problems of the traditional ticketing system include: less scalability, bad load balance, and transaction complexity. To solve these problems, in this thesis, we employ the WS technology to establish a WS-Based Online Ticketing System(WSOTS). The proposed system can improve the process management, reusability, scalability, and system integration.
