ABSTRACT:
The object of the present invention is to analyze association relationships between data items and processes being used in an existing system. By analyzing a program or the like, the type and numbers of access instructions to data items in each step of the program is examined (step13). Then, data item association degree is calculated from the type of access instruction etc., and the values of the association degree are corrected using system requirements etc (step15and step17). Processes having high association degrees are collected together by referencing the corrected valves of the association degree (step21). Based on the groups of collected processes, process division and data item partitioning is performed (step23). Interfaces between processes are then displayed based on divided processes and partitioned data items (step25).
