An Integrated Strategy for Data Fragmentation and Allocation in a Distributed Database Design

A distributed database is structured from global relations, fragmentation and data allocation. A global relation can be divided into fragments and each fragment may itself contain a relation. The fragmentation describes how each fragment of the distributed database is derived from the global relations. The data allocation allows the allocation of discrete sets of fragments to the sites of the computer network supporting the distributed database. The objective of the present work is to develop a strategy for distributed database design that is simple and useful to achieve the objectives of data fragmentation, allocation, and replication. It has been designed to fragment and allocate data in a distributed relational database system using different types of computers on a network.
