Extendening a Temporal Query Language for Supporting Imprecise Data
Abstract
Inaccuracy is a natural property of data in many database applications. For this reason, several techniques are introduced in traditional databases for supporting imprecise data. On the other hand, temporal databases have weaknesses in working with data that have imprecise temporal dimensions. In this paper we will first review available temporal data models and temporal query languages and then will develop a temporal query language for supporting fuzzy querying capabilities.
