The quality of database distribution design, which involves fragmentation and allocation,
should be assessed by the performance of a system. In particular, this applies to non …

The design of distributed database is an optimization problem and the resolution of several
sub problems as data fragmentation (horizontal, vertical, and hybrid), data allocation (with or …

A challenging question is how XML can be used to support distributed databases. This leads
to the problem of how to obtain a suitable, cost-efficient distribution design for XML …

Distribution design for databases usually addresses the problems of fragmentation,
allocation and replication. However, the major purposes of distribution are to improve …

The efficiency and performance of the distributed systems is mainly determined by the
network communications cost between the different sites and execution time of queries. This …

With the move to distributed systems and an increasing emphasis on the use of object-
orientation for new system design, effective distribution of object-oriented applications is …

Depuis de nombreuses années, plusieurs communautés telles que IMS (Intelligent
Manufacturing Systems), HMS (Holonic Manufacturing System) ont suggéré l'utilisation de …

We study the effects of horizontal fragmentation in complex value databases on query
processing using a query cost model. We show that optimisation of query processing and …
