INFORMATION PROCESSOR AND SOFTWARE DESIGN SUPPORT METHOD

摘要

PROBLEM TO BE SOLVED: To provide an information processor which can accurately detect the abnormality of data flow from a sequence diagram including a plurality of processes performed in parallel.SOLUTION: An information processor comprises first detection means and second detection means. The first detection means detects candidates of a message with abnormality by tracking data flow used in relevant messages in a sequence diagram by using the sequence diagram including a plurality of processes in which a plurality of messages including a message transmitting/receiving data between a plurality of objects and a message using data in the objects are executed in parallel. The second detection means detects the message with abnormality in the candidates of the message with abnormality by tracking data flow used in irrelevant messages in the sequence diagram by using the sequence diagram.
