| With the development of the intelligent device such as PDA, Pocket PC, the mobile application market is getting more and more large in Chinese software field. Many domestic software companies are joining in the field of the enterprise mobile applications, even more in the recent days.The mobile application market, with a good view, drives the development of the mobile sync mid-ware applications. The current leading international enterprises, such as Sybase, Microsoft, Oracle, IBM and etc, all have its own sync mid-ware products, which have good functions and performances and also have continuous improving points. But some shortcomings of these products have been found in the implementment process, such as Microsoft's product only supports its own database SQL server; Sybase's product is complex to develop the mobile applications; the core technology is not open and some problems is difficult to solve; they can't support the current existed business systems without special patches, all these defects and shortcomings need to be solved and improved. So the paper, based on these products and making some research on the international sync protocol and taking the good points from them, comes out some good solutions for these defects and shortcomings.Firstly, this paper analyse the system requirements including the gateway engine, server, client and other requirements; Secondly, this paper make the system design including system structure, sync engine, sync protocol, interaction and protocol binding; Thirdly, this paper discuss the system implementation including the technology selection, sync process flow, client and server function development; At last, this paper summarizes the technology features which are core of the ebGate project and the paper.With the design and implementation of this project, it is proved that it is practicable to use XML format to enclose and operate data transferring commands and is much more reference for other likely kind of projects. |
