Data replication methods in distributed sale systems

Abstract

The project and the implementation of replicated data management mechanisms, dedicated to systems operating in distributed environment, were described in this article. The user-defined logic presented in the paper is a part of the bigger distributed system that uses replication and is an example of using different user-defined algorithms. The aim of the analysis was to show the possibilities and the complexity of the problem. Additionally, the analysis presents the way of using commercial software in different scenarios. The major advantage of replication programming is ability to use popular programming platforms and languages which provide programmers with a variety of possibilities. It is a much more flexible solution than programming using the languages of database servers. © 2011 Springer-Verlag Berlin Heidelberg.
