Semantic Modeling of Successive Events Applied to Version Management.
J. H. ter Bekke · 1996
The semantic abstractions classification, aggregation and generalization are extremely useful for modeling complex situations containing time-independent events. This paper shows that they also can be used successfully for modeling of successive events. Here, two situations can be considered: ordering and sequencing. Both will be illustrated with practical examples on workflow and version/configuration management. The solutions do not require special constructs and can therefore be implemented in any programming environment. Keywords: data modeling, semantic databases, ordering, sequencing, version modeling, workflow management, design data management. 1 Introduction The semantic abstractions aggregation and generalization appeared for the first time in the database literature in a series of papers by Smith and Smith [11, 12, 13]. These abstractions are considered to be suitable for modeling complex situations in which different types of relationships occur. Because of their na...
