The Research And Design Of Requirement Tool Based On MDA

With the development of the military information system and the enlargement of the scale, military software faces the increasing pressure. In addition to information technical support, the military information system development focuses on the early requirement elicitation and modeling.By establishing a normal requirement modeling methods, the thesis tries to resolve the issues of the military software efficiency and integrality. The technology of use-case driven requirement elicitation and the methodology of Model Driven Architecture (MDA) are mainly studied, and a new software development method is proposed which incorporates requirement process and MDA development process. The thesis emphasizes on the analysis and design of a new requirement tool based on MDA. The functions which the tool can implement include requirement elicitation, requirement analysis, model transformation, document generation and requirement validation. The Use-case driven technology is adopted to guide users to capture their requirements by the form of tables and templates. A language, named as Use-case Description Specification Language (UCDSL), is developed to describe system functional requirements,which facilitates the automatization of requirement analysis and model transformation. Furthermore, the model transformation rules are established, which include the transformation of requirements to Use-case models, Use-case models to activity diagrams, Use-case models to sequence diagrams and extended CRC cards to class diagrams.
