Centralized databases are becoming bottlenecks for physically distributed organizations. They carry the disadvantages of high communication cost and high data retrieval time. The emerging distributed database technology promises increased availability, reduced cost and improved response time. However, this area needs to research many issues before implementation. Data fragmentation and allocation are very important and critical steps in distributed databases. It is a pivotal area that needs to be investigated properly especially with reference to the telecom sector.
