An Asynchronous Replication Model to Improve Data Available into a Heterogeneous System

Data replication is an important technique for high level data availability, especially applied for distributed systems. To enhance the data access and data reliability, data replication is one of the most important aspects. This paper is proposed a asynchronous replication model. This model also supports heterogeneous system which is currently a very promising system. In our proposed model the main server and replication servers are loosely coupled. Since the structure is loosely coupled and asynchronous model thus there is less dependency on each server. Moreover the proposed model is supporting heterogeneous system, so it will be highly cost minimizing solution for efficient data replication.
