Titel: The Entity Relationship Time Model and the Conceptual Rule Language
Sammanfattning: Recent years have witnessed an increased demand for information  systems which cover a wide spectrum of application domains. This,  inevitably, has had the effect of demanding conceptual models of  enhanced functionality and expressive power than is currently  possible in practice. This paper introduces the TEMPORA modelling  paradigm for developing information system applications from a  unified perspective which deals with definitional, intentional and  constrain knowledge. The paper discusses in detail two of the  components of the TEMPORA conceptual model namely, the Entity-  Relationship-Time (ERT) model and the Conceptual Rule Language  (CRL). The ERT model deals with the structural aspects including time  and complex objects modelling whereas the CRL language deals with  constraints and derivations on the ERT model.
