USING STATE COORDINATOR PATTERN FOR TRANSITION FROM DESIGN INDEPENDENT TO PLATFORM INDEPENDENT MODEL

Abstract

Development of the information system is a stepwise process, starting with requirements definition and proceeding with design and implementation steps. Existing modelling approaches concentrate on formalisation of requirements definition or start at the design model and analyse its transformation to code under specific platform. In this work, a possible method for deriving the design model by integrating requirements definition with chosen software architecture is presented. The proposed transformation based on State Coordinator pattern is a particular case of variety of possible transformations, but it demonstrates the way to formalize step from requirements to design and to shorten the development process.
