Tailoring temporal description logics for reasoning over temporal conceptual models [PDF]

, 2011
Temporal data models have been used to describe how data can evolve in the context of temporal databases. Both the Extended Entity-Relationship (EER) model and the Unified Modelling Language (UML) have been temporally extended to design temporal ...

The skull beneath the skin: entity-relationship models of information artifacts

Int. J. Hum. Comput. Stud., 1996
Data modelling reveals the internal structure of an information system, abstracting away from details of the physical representation. We show that entity-relationship modelling, a well-tried example of a data-modelling technique, can be applied to both ...
