The basic principles of data mining is to analyze the data from different angle, categorize it and finally to summarize it. In today's world data mining have increasingly become very interesting and popular in terms of all application. The need for data mining is that the authors have too much data, too much technology but don't have useful information. Data mining software allows user to analyze data. This paper introduces the key principle of data pre-processing, classification, clustering and introduction of WEKA tool. Weka is a data mining tool. In this paper, they are describing the steps of how to use WEKA tool for these technologies. It provides the facility to classify the data through various algorithms.
