Title

Towards a complete conceptual model : Petri nets and entity-relationship diagrams

Abstract

Shows how entity-relationship (E-R) diagrams and high-level Petri nets can systematically be synthesized into rigorous, yet graphic system models which meet the requirements of conceptual modelling. The idea is to combine the strengths of a widespread technique of modelling static system properties with an also well-known theory of systems and processes and its diagrammatic language. Although Petri nets are primarily used to capture and analyze dynamic system properties, they may also be used for modelling static properties. Based on this capability, they are employed for defining the semantics of E-R diagrams and for complementing the E-R approach. The result is a technique for producing complete conceptual models in diagrammatic form which describe both the static and dynamic properties of the modelled system and are amenable to simulation
