....on the contrary, must be conservative ( Fal74] or temporal ( SA86] RBL87] in the sense that it should not forget anything ever fed to the system, unless explicitly asked for. For such systems, the distinction between intrinsic (or valid) and extrinsic (or transaction) time ( SA86] Bub80] is important. When evolving information systems become available, traditional systems might turn out to be degenerations of these evolving information systems. This paper will present a conceptual framework for a generalized evolving information system. This framework includes fundamental ....

....relationships have received the most attention. These have been called event time, i.e. the real world time at which a fact becomes valid, and transaction time, i.e. the time when this fact is recorded in the database. This distinction has also been referred to as extrinsic intrinsic time [Bubenko, 1980], model system time [LOKI, 1986] and data transaction time [Clifford, 1987] It seems that an ideal conceptual model should be capable of relaxing the assumption of temporal correspondence between the states of the database and the modelled environment. However, this necessity complicates things ....

.... dynamic components refers to the usage perspective i.e how the organisation operates and they are typically viewed as events, actions, transactions and control structures. According to Bubenko a conceptual schema represents abstractions, assumptions and constraints about an application domain [Bubenko, 1980]. More accurately, it represents a user s conceptualisation of the object system. A conceptual schema is based upon a particular modelling formalism which encourages a developer to concentrate on the semantics of the application domain rather than the characteristics of the delivered system. ....
