基于XML和JMS的异构数据交换集成的研究

Research of Heterogeneous Data Integration and Exchanging Based on XML and JMS

随着企业信息化不断深入,对于异构数据集成的要求越来越迫切。为此提出了一种异构数据交换集成的模型。首先构造异构数据库的元数据的模式XML Schema,并建立元数据与XML Schema间的映射,将异构数据表示成XML形式,使用JMS技术完成系统间XML的传输,再根据本地数据库的元数据与XML Schema的映射将XML中的数据转化为本地数据库可用数据,从而较好地解决了异构数据集成和交换的问题。

With the increasing development of enterprise information, the heterogeneous data integration becomes more and more important. So a model of heterogeneous data integration and exchanging based on XML and JMS is brought forward here. First,constructing the XML Schema for the metadata of the heterogeneous database, establishing the mapping between the metadata and XML Schema, expressing the data in the form of XML, employing JMS to transfer data among application systems. And then according to the mapping between the metadata of local database and XML Schema, make the data extracted from XML available to local database. This model can implement the heterogeneous data integration and exchanging satisfactorily.
