Business flow diagram generation program, business flow diagram generation equipment and business flow diagram generation method

摘要

A workflow diagram in which the operational status of a business system is properly reflected and the workflow of a controller can be easily understood is generated. A path extracting means (1c) extracts a processing path from program information indicating the processing procedure of a business program to generate path information indicating a read processing performed in each processing path and an operation screen displayed to be an update processing. A path associating means (1d) associates the processing path in which the data set to be read matches the data set of a transition source and the data set to be updated matches the data set of a transition destination with the transition relation which is the relation between the two data sets successively updated. A workflow diagram generating means (1e) assumes the data set as a node and the transition relation as a link and generates a workflow diagram (4) in which the information indicating the operation screen displayed in the processing path corresponding to the link is added to the link.
