....a temporal database must follow the principle that all data excluded by the user is kept in order to preserve the complete data history. Many temporal models have been researched and specified in the past two decades, most of them just extending conventional data models with temporal features [6, 7, 11, 24, 25, 26, 27]. Handling versions (joining, separating, discarding and justifying wrong possibilities) tends to decrease costs and improve quality of final products. In this context, presenting versions with their respective temporal aspects has the advantage of getting design information related to specific ....
....only in temporal database modeling but also in queries, constraints, real time applications, multimedia temporal synchronization, active databases, deductive databases, and so on. About temporal databases modeling and implementation, a good set of works is grouped by Tansel (et al.) in reference [25]. Jensen also grouped his vast set of published and non published papers about temporal data, query, implementation and design in reference [12] Implementation issues are analyzed by Snodgrass in reference [24] These two concepts, version and time, are mostly treated individually in the ....

.... of logic languages capable to deal with time (see, e.g. 13, 35] On the other hand, in the eld of databases, many approaches have been proposed to extend existing data models, such as the relational, the object oriented and the deductive models, to cope with temporal data (see, e.g. the books [45, 12] and references therein) Clearly these two strands of research are closely related, since temporal logic languages can provide solid theoretical foundations for temporal databases, and powerful knowledge representation and query languages for them [10, 16, 34] Another basic motivation for our ....

Our spatio temporal language is close to the approaches ....

.... alternative way of providing temporal facilities to query languages is by means of constructs yielding a more implicit access to the flow of time, such as the typical temporal connectives next, previous, until, and since of temporal logic [9] Illustrations of these two approaches can be found in [11]. The question of how temporal connectives versus explicit timestamps in temporal query languages relate to each other with respect to expressive power, arises naturally [7, 8] In the present paper, we study this question from various angles.

These are intended to store and manipulate in a principled manner information not only about the present, but also about the past and future (Tansel et al. 93) Tsotras Kumar 96) In questions directed to temporal databases (e.g. 1) 3) it becomes crucial for nldbs to interpret correctly temporal linguistic expressions. 1) What was the salary of each engineer while ScotCorp was building bridge 5 (2) Did anybody leave site 4 before the chief ....

In this context, the constraint database approach [15] appears to be very promising. Constraint databases provide a uniform framework for modeling arbitrarily high dimensional data, ....

We give several examples: In the calendar database, find the meetings that are scheduled within one hour from each other. In the employee database, find the employees who left their jobs within two months of their hiring ....
