چکیده

Object-relational database systems are now being deployed for real use by customers. Researchers and industry users have begun to explore the performance issues that these systems raise. In this paper, we examine some of those performance issues, and evaluate them for object-relational systems in general and for INFORMIX-Universal Server in particular. We describe objectrelational query processing techniques and make some predictions about how they will evolve over the next several years.

A Parallel Algebra for Object Databases

This paper describes an algebra for use with parallel object databases, and in particular ODMG compliant databases with OQL. Although there have been many proposals for parallel relational database systems, there has been much less work on parallel object databases, and on parallel query processing for object databases. The parallel algebra presented in this paper is an extension of an existing...

Deductive Database systems are designed based on a logical data model. Data (as opposed to Relational Databases Management System (RDBMS) in which data stored in tables) are saved as facts in a Deductive Database system. Datalog Educational System (DES) is a Deductive Database system that Datalog mode is the default mode in this system. It can extract data to use outer joins with three query la...

Relational Databases Query Optimization using Hybrid Evolutionary Algorithm

Optimizing the database queries is one of hard research problems. Exhaustive search techniques like dynamic programming is suitable for queries with a few relations, but by increasing the number of relations in query, much use of memory and processing is needed, and the use of these methods is not suitable, so we have to use random and evolutionary methods. The use of evolutionary methods, beca...
