The Research Of Heterogeneous Database Integration Technology Based On CSCW

With the development of the technology of supplying information service on Internet, it is increasingly becoming one of the hot focuses that how to share data between all kinds of data sources and how to improve QoS of information on Internet with scarce resources through network. How to detect and resolve data conflicts and heterogeneity are the fundamental issues. The integration of heterogeneous database is the fundament for integrating the enterprise information and realizing effective management.CSCW is a new research realm with multi-knowledge crossed and supported. It results from the combination of latest information techniques and human collaboration of traditional society. Using teamwork to improve the efficiency of the entire enterprise has become the modern information enterprise objective.Firstly, this paper discusses research background and theory foundation and simply introduces CSCW, Web Services, XML, and then analyzes heterogeneous database integration technology. Based on the analysis on the shortcomings of existent heterogeneous data integration system, this paper discusses in detail the probability of combining heterogeneous data integration system with CSCW, studies the problems of heterogeneous database cooperative work and the new characteristics of heterogeneous database integration management based on CSCW, brings forward the heterogeneous database integration strategy.Database integration technologies provide effective channels for detecting data heterogeneity, modifying data earlier, resolving data incompleteness and inconsistencies, and finally improving data quality for comprehensive usage. This paper mainly solves the data resources call and the data exchange problem based on the distributing and heterogeneous condition, and resolves the three key technological problems-metadata, decomposer and combo, query.
