Reserach on Partitioning Algorithm of Table CoIIegction in Data Exchange Process

摘要

For the order of the table data migration problem in XML-based data exchange system,a table set partitioning algorithm is proposed here,which is an effective solution to the problem of the order of the table data migration.Problems during the data update process among heterogeneous relational database and importance of this research will be introduced first,then detailed discussions of table set partitioning with a feasible algorithm will be proposed;finally,a specific instance will be introduced to describe the XML-based data exchange process principles completely.The instance focuses on table data migration order by using the proposed table set partitioning algorithm.The results show that the algorithm improves the efficiency of resource usage and provide a long-term solution to the real-time data migration,high system efficiency and some other issues.
