摘要：In both Distributed and Real Time Databases Systems replication are interesting areas for the new researchers. In this paper, we provide an overview to compare replication techniques available for these database systems. Data consistency and scalability are the issues that are considered in this paper. Those issues are maintaining consistency between the actual state of the real-time object of the external environment and its images as reflected by all its replicas distributed over multiple nodes. We discuss a frame to create a replicated realtime database and preserve all timing constrains. In order to enlarge the idea for modelling a large scale database, we present a general outline that consider improving the Data consistency and scalability by using and accessible algorithm applied on the both database, with the goal to lower the degree of replication enables segments to have individual degrees of replication with the purpose of avoiding extreme resource usage, which all together contribute in solving the scalability problem for Distributed Real Time Database Systems
