At a conceptual level data modelling consists in providing a structured form of relevant
information and to accompany structures with constraints in order to capture more …

Multiversion databases allow to represent in a database several states, or versions, of the
real world entities. To take into account the new dimension introduced by versioning, new …

We present a new approach to implement an object bitemporal database where both valid-
time and transaction-time are represented. It is based on the DataBase Version model …

We are immersed in a world in which we constantly deal (and cope) with objects and
phenomena in a variety of scales in space and time. With the increase in collaborative and …

Este artigo propõe uma classificação de restrições de integridade para bases de dados com
suporte a tempo e versões. Esta proposta tem o intuito de auxiliar trabalhos futuros de …

Applications requiring a full and efficient management of data feel the need to consider,
beside the current facts, historical and future facts, and to keep the track of the manipulation …

The version concept was initially proposed for controlling design evolution on computer
aided design and software engineering. Time concept has been widely used in software …

This paper proposes the Temporal Versioned Constraint Language (TVCL), which provides
a declarative and non ambiguous way to user specification of constraints for temporal …

Checking integrity constraints in real-time the database is an important field of investigation.
In this paper, we implement topological integrity constraints depending on which user has …

The cooperative construction of data\knowledge bases has recently had a significant
impulse (see Wikipedia [Wikipedia]). In cases in which data\knowledge quality and reliability …
