| 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. | ||
