Fragmentation Techniques for Distribution Database: A Review

Abstract

The wide acceptance of the relational approach in data-processing applications and the continuous improvement of commercially existing relational databases has increased the interest for using database in non-conventional applications, such as computer-aided design (CAD), geographic information systems, image, and graphic database systems. The Centralized and distributed database systems are developed for balancing the load and scattering the data over different sites on an organization. So in order to distribute the database on different sites of an organization, fragmentation methods are used. There is several fragmentation methods reviewed in this paper.
