Abstract:
In distributed database system, replicated
databases are composed of many copies of databases
distributed across different sites. Distributed
applications frequently use replications to achieve
higher level of performance, reliability and
availability. The main challenge of database
replication is to keep the data copies to be consistent
in the presence of updates. In this paper, we study
how the replicated databases can be prevented
inconsistent data among users who access the
replicated database simultaneously. Since, causal
consistency perform operations that are causally
related must be seen in causal order by all processes.
Our study is focused on causally-consistent lazy
model for a data-centric distributed application. For
case study, we consider on Sale Ordering System.
