Researches on Technology of Data Integration Under Distributed Heterogeneous Environment

At present,there is a ubiquity of isolated information islands and data gap among the different departments in enterprises,which leads to the fact that enterprises' computerization can not meet the demand of increasingly severe competionin the market.In order to promote data integration,this paper analyses the present ways of data integration,and proposes a data integration solution which is based on web service.The advantages of this solution include loose Combining,cross-platform,independence of program language,ability to get through firewalls,excellent extensibility.This solution can integrate distributed,autonomous and heterogeneous data sources,and help the different departments share the same information,and enable the enterprises improve their modern management efficiency on the premise of less risk and low cost.
