....name z is an attribute value type or an attribute value or an assertion which has the character of an integrity constraint or a deductive rule which computes values of the underlying property and, q is any temporal relation i.e, during, overlaps, etc. 4. 9 The TEMPORA model The TEMPORA model [Theodoulidis et al., 1990; Loucopoulos et al., 1990] has been developed as part of the ESPRIT project TEMPORA that explicitly recognises the need for information systems which provide a closer alignment between business policy and system operation c.f. Fjeldstad et al., 1979; Balzer et al. , 1983; Mathur, 1987; van Assche ....

The temporal relationships between calendar periods follow a formal calendar system [31,32] which is based on the work reported by Clifford and Rao in [10] with the addition of the calendar unit week . This was considered to be necessary since there is often reference to this unit depending on the particular application domain. Any desirable calendar time unit can be defined as a ....

The term business policy rule is used in this paper to refer to an explicit statement of a constraint expressed in the Conceptual Rule Language (CRL) that exists within a domain ontology as detailed by the ....

....and any constraints which may apply on these components. Recent approaches to conceptual modelling paradigms have begun to address the need to support the modelling process by enriched languages which contain intentional, definitional and constraint knowledge [10] 11] 12] 13] 14] 15] 16] 17][18]. The conceptual modelling language which is used for the task of application domain modelling has been developed within the TEMPORA 2 and the ORES 3 projects and provides mechanisms for three conceptual views namely a structural view, a behavioural view and an active view. These three views ....

Details of earlier work in the process and rule models are reported in [van Assche et al., 1988; Loucopoulos, 1989,Theodoulidis et al., 1990; Loucopoulos et al., 1991, McBrien et al., 1991] The ERT model uses as its basic structure the Entity Relationship approach in order to preserve the well known advantages of this approach namely, graphical display, increased readability and wide acceptance by practitioners. The basic mechanism ....
