Sinopse:
Temporal data is difficult to model because every fact may carry both a valid time and a transaction time. Temporal Database Management opens with an introduction to temporal database research and then develops a sustained treatment of temporal semantics, including valid time, transaction time, now, and the relationships between different temporal data types. The work moves from semantics into temporal query languages, with a fourteen-chapter case study of TSQL2, proposals for temporal extensions to SQL standardization, and an academic temporal SQL design. It then covers temporal database design through normalization, temporal entity-relationship models, and mappings to relational structures, before turning to implementation techniques for temporal joins, indexing, timestamping, and complete temporal query-language support. Built from Christian S. Jensen's research contributions and collaborations with nineteen colleagues, this 1,313-page volume is a substantial reference for researchers and advanced practitioners working with temporal databases. Its five-part structure connects formal foundations, language design, database modeling, and implementation into one coherent research record.
