Use Case Driven Requirement Elicitation Technology And Support Tool For Interactive Access

The requirement elicitation is very important one step in the system performance history, it is a bridge users between software engineering personnel, the software engineering personnel obtains user's intention through the requirement elicitation, forms the basis for the software establishment. The requirement elicitation's quality direct relation software's success or not, is committed step in the software life cycle.This article main elaboration has not provided requirement elicitation process situation in UML, how to use the use case driven method gains the requirement, and mainly launches the research from the following several aspects: First, elaborated the requirements engineering, MDA and use case driven technology in detail, lays the rationale for the research; second, given the Requirement elicitation method. This method which fills out a form by the user, the interactive guidance user expression requirement, basis requirement description information acquisition actor, use case and further obtains the use case model; Third, gave the method to derive collaboration diagram. This method used CRC (Class Responsibility Collaborator) to gain class, and improved the CRC structure, derives for collaboration diagram to build the good foundation; Fourth, designed and realized the requirement elicitation support tool; Fifth, the application requirement elicitation tool has given the teaching management system's requirement elicitation process, derived use case diagram and collaboration diagram.
