Abstract

There are some problems on the order of table data migration
in XML-based data exchange system. Based on these problems, an algorithm of
partitioning table set, which solves those problems on the order of table data
migration effectively, is proposed. First of all, this paper analyses the problems
of data among heterogeneous relational database during the data update process
and demonstrates the significance of the research. After that, based on the
algorithm of partitioning table set theory, which is detail discussed in this
paper, an available algorithm is proposed. Finally, using an example of data
exchange process based on XML, the study describes and discusses how to ensure
the data order migration with the help of the algorithm of partitioning table
set. The results show that the algorithm of partitioning table set improves
the efficiency of resource usage and provides an excellent resolution of some
problems, such as real-time quality and high efficiency of data in the system.
