The query optimization problem

Lack of precise statistical information about the database hampers greatly the optimization of queries in database systems (Raghu, & Johannes, 2003). Good algorithms have to be applied in the process of query optimization if success is to be achieved in a greater manner (Walker, 2007). In this paper, we define a query as a kind of language expression used to describe data elements to be retrieved in the database (Garcia-Molina, Ullhman, & Widom, 2004). Application of queries is done in many different settings. In many cases, users send direct requests to the databases in order to get the general structure of ...

Introduction

Database management systems have become a benchmark tool for defending the computer user from aspects of secondary storage management. They are intended to develop the yield of application programmers and to make easy data access by computer-naive end users. There have been two key areas of research in database systems. One is the scrutiny of data models into which the real world can be mapped and on which interfaces for different user types can be built. Such conceptual models include the hierarchical, the network, the relational, and a number of semantics-oriented models that have been reviewed in a large number of books ...
