....Sno93] which is probably the most infuential attempt towards the development of a bitemporal database system. 20 2.5.1 A Data Model and Query Language For Bitemporal Databases [Sno87, Sno93] present a bitemporal relational model and its query language TQUEL. TQUEL is an extension of QUEL [HSW75] for bitemporal databases. In addition to standard (static) relations, the data model of [Sno87] offers event and interval relations. Event relations are intended for the representation of instantaneous events i.e. events whose time of occurence is specified by a point or a chronon. Interval ....

....model as described in the original definition by Codd [CODD70] has been preserved. A database is composed of a collection of relations that contain tuples with the same fields defined, and the values in a field have the same data type. The query language is based on the INGRES query language QUEL [HELD75]. Several extensions and changes have been made to QUEL so the new language is called POSTQUEL to distinguish it from the original language and other QUEL extensions described elsewhere [STON85a, KUNG84] Most of QUEL is left intact. The following commands are included in POSTQUEL without any ....

QUEL was extended in several directions. First, POSTQUEL has a from clause to define tuple variables rather than a range command. Second, arbitrary relation valued expressions may appear any place that a relation name could appear in QUEL. Third, transitive closure and execute ....
