New Perspectives in Temporal Databases

The research of temporal databases has focused mainly on query languages that incorporate time into conventional query languages and on structural aspects of the temporal representation. Yet, the combination of time and databases has a potential to be more powerful than the current capabilities it supports. In this paper we show the power gained by three extensions to temporal database modeling...

Fuzzy Inclusion Dependencies in Fuzzy Databases

Crisp databases and fuzzy databases are developed to provide users with the ability to store data that can be used in deriving information satisfying their needs. The design of these databases requires several theoretical foundations, efficiency, and ease of use. Thus, they accommodate a wider range of real-world requirements and provide a friendlier environment for man-machine interaction. The...

Fuzzy Join Dependency in Fuzzy Relational Databases

The join dependency provides the basis for obtaining lossless join decomposition in a classical relational schema. The existence of Join dependency shows that that the tables always represent the correct data after being joined. Since the classical relational databases cannot handle imprecise data, they were extended to fuzzy relational databases so that uncertain, ambiguous, imprecise and part...

Fuzzy Queries over NoSQL Graph Databases: Perspectives for Extending the Cypher Language

When querying databases, users often wish to express vague concepts, as for instance asking for the cheap hotels. This has been extensively studied in the case of relational databases. In this paper, we propose to study how such useful techniques can be adapted to NoSQL graph databases where the role of fuzziness is crucial. Such databases are indeed among the fastest-growing models for dealing...

Perspectives of Multivariable Fuzzy Control

The situation and trends in the application of fuzzy logic to control multi-input/multi-output (MIMO) systems are analyzed. The basic steps in designing a control system are considered. Fuzzy control applications are either knowledge-based or model-based. In model-based approaches, the first step is process modeling: Usually, interpolation and universal approximation are the two main features t...
