FREDDI: A Fuzzy Relational Deductive Database Interface

This paper shows an architecture for Deductive Fuzzy RDBMS which integrates two approaches of fuzzy databases: the relational and the logical ones. It uses the first one to represent and manipulate imprecise information and the second one to obtain intensional information. Besides, it shows how it is possible to use the resources offered by a conventional RDBMS together with a deduction module ...

Deductive Extension of a Relational Database System

Logic based knowledge processing systems such as PROLOG based expert systems have shown obvious drawbacks in performing conventional database tasks. Knowledge processing by deduction on a large set of given facts can be better performed by a deductive database system based on Horn logic and relational database theory. A concept is presented to extend an existing relational database system to ma...

Tabling with Support for Relational Features in a Deductive Database

Tabling has been acknowledged as a useful technique in the logic programming arena for enhancing both performance and declarative properties of programs. As well, deductive database implementations benefit from this technique for implementing query solving engines. In this paper, we show how unusual operations in deductive systems can be integrated with tabling. Such operations come from relati...

Accessing a Relational Database through an Object-Oriented Database Interface

Object-oriented database systems (ODBs) are designed for use in applications characterized by complex data models, clean integration with the host programming language, and a need for extremely fast creation, traversal, and update of networks of objects. These applications are typically written in C or C++, and the problem of how to store the networks of objects, and update them atomically has ...

Towards a Fuzzy Object-Relational Database Model

This chapter introduces a fuzzy object-relational database model including fuzzy extensions of the basic object-relational databases constructs, the user-defined data types, and the collection types. The fuzzy extensions of these constructs focus on two main flexible aspects, a way to flexibly compare complex data types and an extension of collection types allowing partial membership of its ele...
