基于XML的异构数据交换技术的研究

随着电子政务的不断发展,政府的各个部门间需要交换的数据日益繁重,因此,基于电子政务的异构数据交换技术的研究显得格外重要。论文提出了基于XML的异构数据交换技术,使用XML可以将来自异构系统的不同数据源的数据很容易的集成在一起,应用软件可以在中间层的服务器上对后台数据库的数据进行集成,然后以XML格式发送给客户端或其他服务器。客户端在接收到数据以后,可以使用本地软件来解析数据,并对数据作进一步处理,这样就能有效地解决网络中日益繁重的异构数据交换问题。

Research on Heterogeneous Data Exchange based on XML

With the continuous development of e-government,data which needs to be exchanged between various government departments is becoming heavier.Therefore,the research based on data exchange of e-government systems in heterogeneous systems is particularly important.Use the XML can integrate the data from different data sources very easy.Application software can integrate data from back-end database server in the middle level,and then,send data to the client or other servers in XML format.The local software can parse the received data,and use the data for further processing.This can solve the increasingly serious problem of heterogeneous data exchange in the network.
