The Heterogeneous Data Integration Based on XML in Coal Enterprise

Based on the analysis of the heterogeneous data environment, the system integration platform is built to resolve the heterogeneous data sharing and mutual visit in view of the status quo of the heterogeneous data and integration demand in the coal enterprise. The system chooses the integration project based on the middleware, constructs the heterogeneous data integration frame based on the XML, gives the flow of integration about the heterogeneous data. XML as a common data model, XML Schema as a schema language to describe the data source, XPath as a global query language, the XML file is operated by the DOM/SAX interface. The schema integration is completed with the Java technique. The middleware integration of the heterogeneous data based on XML is realized in the coal enterprise.
