Abstract:
In distributed system, the database can be
replicated in multiple servers stored at different sites.
Replication is a key to providing high availability
and fault tolerance in distributed systems. A faulttolerant
service always guarantees strictly correct.
There are two fault-tolerant replication systems:
passive replication and active replication. In this
paper, we propose online share trading system using
active replication. To be reliable and fault tolerant,
three active-based replicas will be used for this
system.
