Decision Tree Analysis
A decision tree is a widespread technique of designing and envisaging predictive patterns and systems. It is a tree-structured design of a set of aspects to test in direction to expect the output. Decision trees are effective and accepted implements for prediction and classification. The value of decision trees is because of the reality that, in compare to neural networks, it signifies rules. Rules can quickly be articulated so that individuals can comprehend them or even directly use up in a database retrieve language as structured query language (SQL) so that keep information falling into a certain sort may be accessed. Decision tree technique is mostly used for data classification, and it differed into 2 phases;

Clustering is the method of assembling a set of things in such a way that thing in the similar cluster are more equivalent to each other than those in other cluster. Clustering has turn out to be a more and more essential subject with the explosion of material accessible via the Internet. It is an essential implement in data mining and information finding. Signifying data by a small number of clusters automatically fails specific fine information, but accomplishes generalization. It signifies many data items by few groups, and therefore, it models data by its groups. Cluster analysis is an essential data mining method applied to discover data breakdown and design data. By clustering the data, individuals can find the data dissemination, examine the individual of each group, and make additional study on specific groups. Furthermore, cluster analysis typically proceeds as the preprocessing of other data mining processes. Consequently, cluster analysis has turn into a very effective research subject in data mining, and the use of cluster analysis in data mining has 2 key phases; first, clustering analysis can be benefited as a pre-processing phase for the other processes such as structures and classification process, and also can be benefited for further parallel examination. Second, it can be benefited as a separate implement in order to obtain the data delivery, to examine each group descriptions,
