Abstract

Recent research activities in the area of Temporal Databases have revealed some problems related to the definition of time. In this paper we discuss the problem arising from the definition of valid time and the assumptions about valid time, which exist in current Temporal Database approaches. For this problem we propose a solution, while we identify some consistency problems that may appear in Temporal Databases, and which require further investigation.
