The need to design an optimally distributed database is increasingly important with the
growth of information technology and computer networks. However, designing a distributed …

In distributed database systems, tables are frequently fragmented and replicated over a
number of sites in order to reduce network communication costs. How to fragment, when to …

В данной работе мы рассмотрели различные методы организации физического
уровня СУБД: вертикальное и горизонтальное фрагментирование, а также вкратце …

Distributed database functionality depends on sites responsible for the allocation of
fragments. The aims of the data allocation problem (DAP) are to achieve the minimum …

The Performance and the efficiency of a distributed database system depend highly on the
way data are allocated to the sites. The NP-completeness of the data allocation problem and …

The effectiveness distributed database systems highly depends on the state of site that its
task is to allocate fragments. This allocation purpose is performed for obtaining the minimum …

An efficient functionality of any distributed database system “DDBS” is highly dependent on
its proper design in terms of the adopted fragmentation and allocation methods. However …

An efficient way to improve the performance of database systems is the distributed
processing. Therefore, the functionality of any distributed database system is highly …

Allocation of data or fragments in distributed database is a critical design issue and requires
the most effort. It has the greater impact on the quality of the final solution and hence the …
