Every day, we generate a huge amount of data from different sources such as social networks, business transactions, and clinical records. These data are stored in databases as row data, and we do not benefit from the potentially useful information that we could extract from them. However, various data mining (DM) techniques and tools have been developed to turn this growing volume of data into valuable information. DM, or Knowledge Discovery in Database (KDD), is defined as “the analysis of (often large) observational data sets to find unsuspected relationships and to summarize the data in novel ways that are both understandable and useful to the data owner [1].” In other words, DM can be useful and effective in extracting important, relevant information that has not previously been discovered. DM methods and techniques provide significant potential to organizations and researchers to discover implicit information in various areas, including bioinformatics, genetics, and education.
