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

Receiver synchronization of continuous media streams is required to deal with delay
differences and variations resulting from delivery over packet networks such as the Internet …

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 …

In this paper, a new dynamic data allocation algorithm for non-replicated distributed
database systems (DDS), namely the threshold algorithm, is proposed. The threshold …

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 …

A method of mapping data into a table includes identifying pointers of a source portion and
target portion and switching the metadata pointers of the target portion to be those of the …

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 …

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

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 …
