Object-oriented systems modelling method based on Jackson approach

Abstract

This paper proposes an object-oriented information system development method that is based on the modelling approach of the Jackson method. Like the Jackson method, the proposed method separates the consideration of the real world subject matter about which a system is to compute from the function to be provided by a system for its users. Events and functions are the main information sources by which domain objects and other function-related objects are identified and modelled. The modelling approach of the proposed method is thoroughly discussed with the use of a Student-Records System as the mainline example.
