A Review on Utilising XML as the Mediated Layer for Data Integration

摘要

Data integration is crucial to establish a good solution for combining heterogeneous data sources to enable users access these sources through a unified view. XML technology has powerful features to exchange, integrate and store complex data into data warehouse actively by communicatingwith structured, semi-structured and unstructured data. In addition, web-based systems and XML data integration approach facilitate real-time integration for better data analysis and keeping data updated. This paper reviews the latest approaches for integrating heterogeneous data sources throughXML technology as a mediated layer. In addition, we suggest the grouping of these approaches, and more importantly gives insights on the future direction for data integration.
