在網際網路尚未普及的時代，企業間的交易通常是透過電話連繫或傳真機來下訂單及回覆訂單。人工作業常造成訂單版本的錯誤和訂單數量不符等現象，而且需要花費相當的工時及人力來處理。本論文之研究企圖運用網路服務（Web Services）技術及國際標準組織─RosettaNet所制定的供應鏈資料交換標準來建立一高安全性資料交換系統並用以解決企業間跨平台系統整合及資料交換的問題。資訊安全方面則是採用SSL安全機制來達成。希冀藉此能建立一高安全性之供應鏈體系間電子化資訊交換機制，同時來提昇企業間交易的效能與效率。系統經實驗及效益評估，其結果顯示能獲得幾點顯著之質性效益，包括建置具安全性之整合B2B交易平台、節省開發及後續的維護人力成本、減少資料錯誤、避免人工重複資料輸入、訊息監控機制得以有效建立等。從量化評估之數據顯示，企業間交易亦因此獲得顯著的效能提昇。

In the age of yet-popularity of the Internet, the trading between businesses was generally taken through the connection of telephone and facsimile to place order and respond the order. Human operations very often caused the error of order version and inconsistency of the quantity specified in the order.The research of this paper attempts to apply the technologies of Web Services and standards of data exchange for the supply chain set up by the international organization of standardization-RosettaNet to establish a high-secure data exchange system to solve the problem of system integration crossing the system platform between businesses. The SSL mechanism is adopted to achieve the information security. Hopefully it is able to build a high-secure electronic data exchange mechanism in a supply chain system by taking this implementation, in the meanwhile to enhance the effectiveness and efficiency of trading between businesses.Through the experiment and benefit evaluation of the system, the results shown that several significant qualitative benefits may be obtained, which include constructing a secure with integrated business-to-business trading platform, saving the labor cost of development and afterward maintenance, reducing data error due to the elimination of unnecessary human duplicated data entry, and being able to establish a message monitoring and controlling mechanism. The data shown from quantitative evaluation, the significant enhancement of business performance between business trading is thus obtained as well.
