Reseña del editor:
Temporal databases have been an active research topic for at least fifteen years. During this time, several dozen temporal query languages have been proposed. Many within the temporal database research community perceived that the time had come to consolidate approaches to temporal data models and calculus based query languages, to achieve a consensus query language and associated data model upon which future research can be based. While there were many query language proposals, with a diversity of language and modeling constructs, common themes kept resurfacing. However, the community was quite frag mented, with each research project being based on a particular and different set of assumptions and approaches. Often these assumptions were not germane to the research per se, but were made simply because the research required a data model or query language with certain characteristics, with the partic ular one chosen rather arbitrarily. It would be better in such circumstances for research projects to choose the same language. Unfortunately, no existing language had attracted a following large enough to become the one of choice. In April, 1992 Richard Snodgrass circulated a white paper that proposed that a temporal extension to SQL be produced by the research community. Shortly thereafter, the temporal database community organized the "ARPA/NSF In ternational Workshop on an Infrastructure for Temporal Databases," which was held in Arlington, TX, in June, 1993.
Reseña del editor:
This book includes an overview of the scope of the design of the TSQL2 Temporal Query Language, a listing of the design goals for the language, a brief introduction to the major concepts of the language, a detailed examination of each of the language's major design decisions, discussing alternatives and surveying previous approaches, and a detailing of the changes that would be necessary to augment a conventional, non-temporal data base management system (DBMS) to support the facilities of TSQL2. The book also contains the language specification itself, as an upward compatible extension of SQL-92. The TSQL2 Temporal Query Language is an edited collection of papers intended for use as a reference by academics and industry professionals interested in temporal databases research. This book is also suitable as a secondary textbook for a graduate level course on temporal databases.
