Research For Heterogeneous Data Integration Middleware Based On XML

With the development and popularization of information technology anddistributed applications, both enterprise environment and the enterprisemanagement pattern have a huge change. Enterprise information resourcesmanagement faces a serious challenge. Traditional data access has become themajor bottlenecks in the enterprise network information management.Heterogeneous data integration’s task is to provide a unified platform for users.Thereby shield the different of the bottom data source. Enable users can seamlesslyand flexibly access these heterogeneous data.This paper analyzes the data integration status and the defects of the prior art.Discussed the key technologies of the pattern implementation, come up with aheterogeneous XML-based data integration middleware solution. Enable users cantransparent access to heterogeneous data sources in each net node. Only need userssimply specify the data format to be acquired. Data query, as well as the integrationof heterogeneous data is done automatically by the system does not require users toconsider. This system provides functions of obtain the data pattern from datasources, convert data pattern of the data source into the local pattern, integrate thelocal patterns into a global pattern and global pattern-based query. User query datainformation in distribute data sources through this system like query datainformation with one table. Just the system completed query decomposition anddata integration. Functions in the wrapper of this system is been encapsulated intothe Web Service, mediator and wrapper communicate with SOAP messages, so thatthe system has the ability to penetrate the firewall. At the end of this paper, On thebasis of summing up this paper, in conjunction with data integrated systemdevelopment trends in number of problems to be further in-depth analysis andresearch.
