Abstract

In this paper we discuss access to object attributes in a multigranular temporal object-oriented data model that handles the expiration of dynamic attributes, according to the age of data and their granularity [4]. Different strategies can be applied, with respect to available data and to the preferences specified by the user on either accuracy or efficiency in executing a query. We devise some properties of object access that can be applied to speed up the query process, such as the invariance of the queries results with respect to expiration operations, and the static detection of unsolvability of a query.
