Now days due to rapid growth of data in organizations, extensive data processing is a central point of Information Technology. Mining of Association rules in large database is the challenging task. An Apriori algorithm is widely used to find out the frequent item sets from database. But it will be inefficient in case of large database because it will require more I/O load. Later drawback of the Apriori algorithm is overcome by many algorithms / parallel algorithms (model) but those are also

... ficient to find frequent item sets from large database with less time and with great efficiency. Hence hybrid architecture is proposed which consists of integrated distributed and parallel computing concept. The main idea of new architecture is that we combine distributed as well as parallel computing in such a way that it will be efficient to find out frequent item sets from large databases in less time. It also handle large database with efficiently than existing algorithms.
