With the explosive growth of information sources available on the World Wide Web, it has become increasingly necessary for users to utilize automated tools to find the desired information resources, and to track and analyze their usage patterns. Association rule mining is an active data mining research area. However, most ARM algorithms cater to a centralized environment. In contrast to previous ARM algorithms, Optimized Distributed Association Rule Mining (ODARM) is a distributed algorithm for geographically spread data sets that aimed to reduces operational/ communication costs. Recently, as the need to mine patterns across distributed databases has grown, Distributed Association Rule Mining (DARM) algorithms have been developed. These algorithms assume that the databases are either horizontally or vertically distributed.
