Title
Database models for infinite and indefinite temporal information
Source
Information systems. 19(1994) no.2, S.141-173

Abstract
Representation and querying of temporal information can benefit from the integration of techniques from constraint databases, database models for indefinite information and reasoning about temporal constraints. Presents a hierarchy of temporal data models: temporal relations, generalized temporal and temporal tables. Studies the semantics of these models and develops algebraic and calculus query languages for them. The proposed models can be useful to sever novel applications including planning, scheduling, project management, medical information systems, geographical information systems and natural language processing systems
