Research on virtual approach about heterogeneous data integration based on XML

With the development of information technology,Web-based data becomes the mainstream of today's data,but data on Web are mostly heterogeneous.More and more people need to access all kinds of heterogeneous data,so there must be a kind of system which can support heterogeneous data integration.There are many kinds of methods that can carry out heterogeneous data integration,but this paper introduced a kind of architecture of the virtual approach for heterogeneous data integration based on XML in order to solve the problem of heterogeneous data integration on Web.It proposed to use the virtual approach to carry out heterogeneous data integration,and finally introduced the technology of data cleaning which could solve the integration of heterogeneous data better.
