 摘 要
     
 隨著企業的不斷發展和壯大, 企業的總部與分公司處于不同地區的情況越來越多,為了使企業內部使用相同的數據, 大多數企業都采用了數據庫提供的同步技術來解決這一問題, 但該方法操作難度較大, 而數據庫提供的同步技術也會因網絡、電力等原因造成數據同步無法進行, 引起數據的丟失等。為了簡化操作難度, 本文編寫了一段程序來解決數據庫之間的同步問題,不論數據庫是否提供同步技術都可實現數據庫同步。
 文章分析了常見的同步策略和目前的數據同步解決方案，闡述了XML、Web在程序開發、數據傳輸等方面的技術優勢。通過對數據同步目標、數據的傳輸方式和傳輸格式等關鍵問題的分析，提出了一種采用C/S模式，基于XML技術和Web服務開發的系統同步模塊的實現方案，建立了相應的平臺模型和系統框架，并采用基于.NET平臺的開發工具實現了該模型，包括客戶端變化數據的提取、數據發送、數據接收等功能，完成了系統數據同步的目標。

The Performance of Data Synchronization Module of the Composite Entertainment System Constructed On the XML Technology
 
 ABSTRACT
 
 With the development of the enterprises, it is becoming common that an increasing number of the enterprises have their branches separated from the places of the headquarters. Most enterprises adopt the synchronous technology offered by the databases to solve this problem so that the same data can be used in different places synchronously. However, the synchronization offered by the databases cannot work well and even lose the data because of the problem of the network and electricity. To decrease the difficulty of operation, the author intended to write a set of programs to offer the method to solve the problem of synchronization between different databases even if the synchronous technology is not offered by the databases.
 
 The article analyses the hackneyed synchronization strategy and the solution of data synchronization at present. Secondly, it introduces XML、Web and analyses the technology advantages in programming、data transmission and so on. Finally, it proposes a data synchronization platform model which adopts the C/S model and is based on XML technology and Web Service and establishes the model and the frame of the platform by analysis of the goal of the data synchronization and the problems of data transmission mean and form. The model was developed by tools based on .NET, and it has the function of distilling changed data, sending data and receiving data realizing the data synchronization of the system.
