基于Web Service的数据库同步系统的设计与实现
摘 要
结合当前流行的Web Service和ADO.NET技术构造了一个不受平台限制的异构数据库同步系统。实现了处于Internet上的Sql Server2000向Oracle 的单向同步功能,能够基于IP的安全身份验证功能,多个IP实现了净量数据的传输。对同步的配置信息采用XML存储,采用Windows应用程序界面化配置,操作方便、易懂。
因为同步环境是对处于Internet上的异构数据库的实时同步;在设计与开发中,重点关注异构数据库的同步以及数据传输的可靠性;探讨能实现可靠数据的同步,以及传输的高效性。介绍了实现系统的思路以及所需的关键技术。系统用到的相关技术有捕获技术Windows 托盘服务、多线程处理、以及网络消息机制、多IP同步、同步IP权限验证、同步表名及字段以及字段类型的可配置、异构数据类型的转换、Web Service等。

The Design and Implementation of Database Synchronization System Based on Web Service
Abstract
We can construct the Heterogeneous database synchronous system using Web Service. It has realized the function of one-way synchronous from SQL Server2000 to Oracle. It has some functions, the security authentication of IP, the data transmission of IP, the Synchronization configuration using XML storage and the windows application program UI which can make this system be operated easily.
Because the synchronous environment will be real-time synchronous for heterogeneous database on the Internet, in the design and implementation, this system has showed the synchronization of heterogeneous database and data transmission reliability, achieving the synchronization of reliable data, the security methods of data transmission, and the efficiency transmission. It will display the ideas of realization and the necessary critical technologies. There are some relevant technologies that this system used, for example, the capture technology, the windows tray service, multi-thread processing, and the network news mechanism, and so on.
