In real world, it is very common that some objects or concepts have properties with a time-variant or timerelated nature. Modelling this kind of objects or concepts in a (relational) database schema is possible, but time-variant and time-related attr

This paper investigates the storage compactness of temporal merges. A temporal merge is a joint representation of a set of snapshots of the same database at different points in time. An axiomatic requirement for temporal merges is that each individua

Time modeling is an important issue in information management. Both traditional and soft computing approaches have been thoroughly studied in the existing literature. Traditional approaches are specifically designed to efficiently deal with perfect t

Database queries usually consist of elementary query conditions combined with each other using connectives. Elementary query conditions are typically Boolean-valued functions defined over one or more properties. These elementary query conditions may

Currently, many existing information systems contain large amounts of data. Prior research shows that many of these data represent time (domain) intervals and many of those may be subject to uncertainty.

In existing literature, many proposals have concerned the modeling or handling of imperfection in time in information systems. However, although reviews, surveys and overviews about either imperfection or time in information systems exist, no reviews

Databases contain data and database systems governing such databases are often intended to allow a user to query these data. On one hand, these data may be subject to imperfections, on the other hand, users may employ imperfect query preference speci

Database systems contain data representing properties of real-life objects or concepts. Many of these data represent time indications and such time indications are often subject to imperfections. Although several existing proposals deal with the mode

Recently a new line of research on database querying has been triggered by the observation that humans usually express their preferences using both positive and negative statements. This results in semantically richer bipolar queries consisting of co

One of the most important purposes of information systems is to allow human users to retrieve their data or information or knowledge derived from their data. These data may be subject to imperfections and often represent time indications, as time is
