Modelling Information Systems as Object Societies

摘要: Conceptual modelling of complex information systems requires the use a formal design approach covering both static and dynamic aspects system modelled Universe Discourse. Viewing an as collection communicating objects is close to intuitive perception such on conceptual level. Objects have local state, show specific behaviour, communicate with other may be itself composed from smaller objects. This article presents abstract concept discusses language features specification for describing object systems. The presented Troll2 supports structuring mechanisms semantic data models together process constructs cover dynamics. Extensions framework are discussed step cooperating agents allowing more flexible structures.
