Description
Summary:A fuzzy temporal database contains fuzzy temporal data. In fuzzy temporal database transactions have deadlines or timing constraints. This situation requires the integration of heterogeneous data in an unique platform in which time representation and management techniques should be considered. In this work, an architecture which makes possible heterogeneous data integration within a homogeneous framework for time representation and management is presented. This paper is focused on the design and implementation of a general purpose fuzzy temporal model. A communication language is also provided to make updates and retractions of fuzzy temporal information possible, as well as the answering of complex fuzzy temporal queries. The proposed model offers an optimal trade off between expressive power and efficiency.
