TSQL2, a temporal extension to the SQL language standard, was designed by the TSQL2 committee, which was formed in July, Snodgrass chaired the TSQL2 language design committee. The committee produced a preliminary language specification the following January, which appeared in the March ACM SIGMOD Record. TSQL2  is a query language for temporal relational databases, derived from SQL, that supports both VT and TT. It minimizes the syntactical changes from SQL, it covers most features of existing temporal query languages, and it introduces some original elements. Temporal aspects have also been considered in the devel-.

In TSQL2, rather than have the user actually see how the temporal tables are implemented (as we discussed in the previous sections), the TSQL2 language adds query language constructs to specify various types of temporal selections, temporal projections, temporal aggregations, transformation among granularities, and many other concepts.

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.

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.
A temporal query language is usually quite closely associated with a temporal data model that defines the underlying data structures to which the language applies. Historical Background When the relational data model was proposed by Codd, he also proposed two query languages: the relational calculus and the relational algebra.

A temporal database is a database with built-in time aspects, for example a temporal data model and a temporal version of Structured Query Language (SQL). More specifically the temporal aspects usually include valid-time and attributes go together to form bitemporal data.
