Role and Request Based Conceptual Modeling - A Methodology and a CASE Tool

摘要

This paper contains a brief description of the R~2M (Role and Request Modeling) method and its supporting visual modeling CASE (Computer Assisted Software Engineering) tool. R~2M is a modeling method for creating Conceptual Models of work systems using a combination of ontological and object-oriented concepts. The ontological principles serve to define the meaning of modeling constructs in terms of domain semantics, and to derive rules guiding the modeling process. The R~2M CASE tool is a graphical software tool that supports the creation of models according to the R~2M method. Guided by the principles of R~2M, the tool helps assure the semantic integrity of models, and enables management of complex models via decomposition (i.e. including more details at lower abstraction levels). The tool can help ensure consistency between different modelers and completeness of models.
