Summary: | Distributed system model best suits on
the organizational structure of companies that,
because of their business needs, are geographically
distributed. For the organizations that are expanding
globally, the data exchange between multiple
databases and applications has become more
important. In distributed environments we are facing
new problems that are not relevant in centralized
environments, such as data fragmentation and
replication. Designing a distributed database system
also involves the decisions about placing the
information on different sites in a computer network.
The problem of data fragments allocation on different
sites is closely related to data replication in
distributed databases. In this paper we will
concentrate on data allocation problem, revealing the
data allocation importance in the process of the
distributed database design in correlation with data
fragmentation. In addition, we will analyze the
available strategies and methods of data allocation. |
