The main task of distributed database is how to fragment the global database into small
fragments, how to allocate and replicate the fragments among different sites over the …

The query optimiser is a vital part of any distributed database mechanism. Reducing the
execution period of the query depends on reaching an ideal query execution plan. Due to …

The performance and efficiency of the distributed database system (DDBS) design are
dependent on proper data fragmentation, reallocation, and replication of global relations. In …

Choosing appropriate fragment allocation in Distributed Database Systems is an important
issue in design of Distributed Database Management System. Several fragmentallocation …

This paper addresses the problem of determining the optimal location to place a fragment
(object) in a distributed non-replicated database. The algorithm defined takes into …

Distributed databases (DDBs) provide smart processing of large databases, the problems of
fragmentation and allocation are vital design problems in addition to the centralized design …

Allocating data fragments in distributed database systems is an important issue in distributed
database (DDB) systems. In this paper, we are going to improve the effectiveness of current …

Determining the location of the storage of data on different nodes of a distributed system is
called allocation of pieces of data and is considered as the most important factor influencing …

Distributed databases were developed in order to respond to the needs of distributed
computing. Unlike traditional database systems, distributed database systems are a set of …

Since accurate migrations of data fragments in distributed database systems, known
dynamic fragment allocation, play an important role in amendment of distributed database …
