RELATIONAL ASPECTS OF RELATIONAL DATABASE DEPENDENCIES

Dependencies in Relational Databases

Functional Dependencies Analyse in Fuzzy Relational Database Models

This paper presents a literature overview of Fuzzy Relational Database Models with emphasis on the role of functional dependencies in logical designing and modeling. The aim is the analysis of recent results in this fi eld. Fuzzy set theory is widely applied for the classical relational database extensions resulting in numerous contributions. This is because fuzzy sets and fuzzy logic are power...

Induced Dependencies in Relational Databases†

With the growth of database complexity and size it is becoming increasingly necessary to automate the analysis of data. Part of this automation is the development of inductive algorithms to search for characterising rules. The paper introduces the formal concept of an induced dependency as a descriptor for the relationships which characterise the data within a database. This is done within the ...

The Relational Database Aspects of Argonne's ATLAS Control System

∗ Undergraduate Research Participants Abstract Argonne’s ATLAS (Argonne Tandem-Linac Accelerator System) control system comprises two separate database concepts. The first is the distributed real-time database structure provided by the commercial product Vsystem [1]. The second is a more static relational database archiving system designed by ATLAS personnel using Oracle Rdb [2] and Corel Parad...

Object-relational database metrics

Object-relational databases will replace relational systems to become the next great wave of databases because they combine traditional database characteristics with object-oriented principle. So, it is fundamental to propose metrics for control the quality of this kind of databases. But metrics definition must be done in a methodological way, it is necessary to follow a number of steps for ens...
