There are several algorithm for knowledge data discovery, like classifying, clustering and mining [2].

With the existence of this dashboard is expected to be a solution for the learning process to monitor the academic condition and then could take the right decision. However, organizations are recognizing that traditional data warehouse technologies are dying to meet new business requirements, especially around streaming data, real-time analytics, large volumes of unstructured and complex data sets.
