Abstract :
A temporal database model capable of representing absolute, relative, imprecise, and infinite temporal data is proposed. The model is based on temporal tables such as relation-like representations that can contain variables constrained by the formulas of a temporal theory. An algebraic query language for temporal tables is defined, and some problems related to query answering are discussed
