A knowledge based technique for the process modelling of information systems: the Object Life Cycle Diagram

Abstract

This paper presents a new technique for IS process/behavioural modelling. Object Life Cycle is proposed as an extension of the conventional entity life history diagram with a Petri-Net based formalism and an Event-Precondition-Action process representation. A normalization approach for IS process modelling is suggested and several OLC norms discussed. Generalization and aggregation of OLCs are explored along with the concepts of a substate and a component event. Coordination of the objects via event raising is visualized by the Inter-Object Communication Model. Finally, we discuss how OLCs relate with RUBRIC rules and data flow diagrams.

“…These techniques have been mainly used in the manufacturing industry case study in the incremental BPR mode (Appendix 1). Some of these modelling tools were selected from the existing literature (Davenport, 1993; Douma and Schreuder, 1992; Fama and Jensen, 1983a,b; Harrington, 1991; Ip and Holden, 1992; Williamson, 1975, 1986), and others were developed to satisfy specific management needs. Different analysis techniques are applied to the structural and behavioural/process perspectives.…”

“…It was also found to be useful in analysing the abstraction levels that were created from functional decomposition in the behavioural and process perspectives. According to Ip and Holden (1992)), in order to assess the usefulness and effectiveness of abstraction levels that organize IS conceptual models some tests are derived: Test of clarity . An abstraction should bear a clear and well defined relationship to its refinement.…”
