Data Updating in Heterogeneous Data Integrated System Based on P2P
Zhu Zheng · Communications technology · 2009
In the heterogeneous data integrated system based on P2P,the database system deployed on each heterogeneous data peers has the characters of distribution,independence and heterogeneity,and the data in the peers needs to carry on the exchange and conformity,thus making the data updating an important issue of the data integrated system. The existing data integration technologies,such as specialized transformation tool,the federal database and so on,has the flaws of bad flexibility and interaction,this article thus proposes the plan which combines the package with the JXTA correspondence adapter,thus realizing the database information access,the two-way integrated information transmission,the resource discovery and active synchronization of the difference information between heterogeneous data peers.
