APPARATUS AND METHOD FOR REUSING PREVIOUSLY USED CASE FOR EXTRACTING DEMANDING ITEM OF OBJECTED-ORIENTED SYSTEM AND METHOD FOR EXTRACTING DEMANDING ITEM

摘要

PURPOSE: An apparatus and method for reusing a previously used case for extracting demanding item of an objected-oriented system and a method for extracting demanding item are provided to reduce a time and a cost for developing a software by analyzing a functional requesting item of a software more exactly through a reuse of an existing case in a demanding item analyzing stage of a software developing process. CONSTITUTION: An actor input unit(301) receives an actor extracted from a problem area. A using case input unit(302) receives a using case newly extracted from a problem area. A using case summary description input unit(303) receives a simple explanation with respect to the extracted using case in accordance with a fixed input form. A using case detailed description input unit(304) describes an event flow of the interior of a using case. Another using case input unit(305) inputs a using case scenario in accordance with a fixed input form based on a using case description. A using case description unit(306) receives a sequence diagram, an activity diagram and a status diagram for a standardization of a using case. A using case searching unit(307) searches a similar using case in accordance with a demand by a user. A using case form managing unit(308) manages a version of a stored using case. All using cases, which are extracted or changed, are stored in a storing portion(309).
