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.
