Abstract: The distributed data processing is an upstanding way to improve reliability, availability and pursuance of a database system. In this paper we will concentrate on data allocation problem with the aim to persuade an optimal distribution of data in the process of the distributed database architecture in interconnection with data fragmentation. Efficient allocation of fragments requires a proportion between costs, performance and data distribution restrictions. The allocation of fragments is closely related to the replication of data from distributed databases. In addition, we analyzed the cost of fragmentation and replication.
