A Conceptual Model of Fuzzy Temporal Databases: Algebra

摘要：

Most of the database research on modeling time has concentrated on the definition of a particular temporal model and its incorporation into a (relation or object) database management system. This has resulted in quite a large number of different temporal models. Representation and querying of temporal information can benefit from the integration of techniques from constraint databases, database models for fuzzy information and reasoning about temporal constraints. With this perspective in mind, we first present a hierarchy of temporal data models. Then we study the semantics of these models and develop algebraic for them.
