An apparatus and method for reusing use cases for capturing requirements of an object oriented system and method for capturing requirements using thereof
An apparatus and method for reusing use cases for capturing requirements of an object oriented system and method for capturing requirements using thereof
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).
