This is because, in some temporal data models, the semantics of queries and updates depend on the instant at which they are issued. In the setting of ODMG, the set of queries Q not only includes those which are submitted to the OQL interpreter, but also, all accesses to class extents and object properties via application programs.
Mannisto, R. Sulonen The concepts are roughly illustrated in Fig. 2, in which generic objects are represented by ovals. Inside an oval are the versions of the generic object as small circles, each with an effectivity interval next to it. Solid-line arrows represent is-instance-of relations and dottcd-linc arrows relations in schema and between individuals. The concepts provide the basics for recording the history of objects. The concepts can be used in various ways, and therefore, the modelling of evolution is far from solved by just providing the basic concepts.
