The primary objective of this research is to develop a process to accurately predict useful data from the huge amount of available data using data mining techniques. Data Mining is the process of finding treads, patterns and correlations between fields in large RDBMS. It permits users to analyse and study data from multiple dimensions and approaches, classify it, and summarize identified data relationships. Our focus in this thesis is to use education data mining procedures to understand higher education system data better which can help in improving efficiency and effectiveness of education. In order to achieve a decisional database, many steps need to be taken which are explained in this thesis. This work investigates the efficiency, scalability, maintenance and interoperability of data mining techniques. In this research work, data-results obtained through different data mining techniques have been compiled and analysed using variety of business intelligence tools to predict useful data. An effort has also been made to identify ways to implement this useful data efficiently in daily decision process in the field of higher education in India.
Mining in educational environment is called Educational Data Mining. Han and Kamber describes data mining software that allow the users to analyze data from different dimensions, categorize it and Summarize the relationships which are identified during the mining process. New methods can be used to discover knowledge from educational databases. Every data has a lot of hidden information. The processing method of data decides what type of information data produce. In India education sector has a lot of data that can produce valuable information. This information can be used to increase the quality of education. But educational institution does not use any knowledge discovery process approach on these data. Information and communication technology puts its leg into the education sector to capture and compile low cost information. Now a day a new research community, educational data mining (EDM), is growing which is intersection of data mining and pedagogy. First chapter of the thesis elaborates the knowledge data discovery process, data mining concept, history and application of data mining in various industries.

Excerpt from the Book
1.1 KNOWLEDGE DATA DISCOVERY
Most authors have different definitions for data mining and knowledge discovery. Goebel and Gruenwald [1] define knowledge discovery in databases (KDD) as “the nontrivial process of identifying valid, novel, potentially useful, and ultimately understandable patterns in data” and data mining as “the extraction of patterns or models from observed data.” Berzal et al. [2] define KDD as “the non-trivial extraction of potentially useful information from a large volume of data where the information is implicit (although previously unknown).” G&G’s model of KDD, paraphrased below, shows data mining as one step in the overall KDD process:
1. Identify and develop an understanding of the application domain.
2. Select the data set to be studied.
3. Select complimentary data sets. Integrate the data sets.
4. Code the data. Clean the data of duplicates and errors. Transform the data.
5. Develop models and build hypotheses.
6. Select appropriate data mining algorithms.
7. Interpret results. View results using appropriate visualization tools.
8. Test results in terms of simple proportions and complex predictions.
9. Manage the discovered knowledge.
Although data mining is only a part of the KDD process, data mining techniques provide the algorithms that fuel the KDD process. The KDD process shown above is a never-ending process. Data mining is the essence of the KDD process.
