A Meta-Model for Textual Use Case Description
نویسنده
چکیده
A Use Case is a specification of interactions involving a system and external actors of that system. The capability for use case modeling has been integrated to the Unified Modeling Language (UML) since its inception. However, use cases are only defined at an abstract level, as the UML Specification does not discuss use case description in text form. In this paper, we propose an abstract syntax for textual use case description as a meta-model extension of the UML Specification. This meta-model is based on elements commonly found in use case templates. The meta-model also includes OCL constraints for ensuring consistency with the UML specification.

Several studies have proposed meta-models for textual representations of use cases. Each of these meta-models has different goals and viewpoints, with either varying concepts and relationships or different semantics for the same concept. In Model-Driven Engineering approaches where there is no compatible proposal or a more appropriate viewpoint, or where there is no intention to limit the appro...

By considering Sudoku as a language, where a Sudoku puzzle is an instance of the language, we are able to apply meta-model-based technologies for the implementation of Sudoku, including correctness checking of a puzzle and solving strategies. The description of Sudoku includes not only the structure of Sudoku, but also covers constraints, textual representation, graphical representation, and be...

متن کاملPetri Nets Based Formalization of Textual Use Cases
A Use Case is a specification of interactions involving a system and external actors of that system. The intuitive, user centered nature of textual use cases is one of the reasons for the success of the use case approach. A certain level of formalization is however needed to automate use case based system development, including tasks such as model synthesis, verification and validation. In this...
