This page intentionally left blank PREFACE This book is intended as a text in data mining and warehousing for engineering and post-graduate level students. We have attempted to cover the major topics in data mining and warehousing in depth. Advanced material, however, has been put into separate chapters so that courses in a variety of levels can be taught from this book. A brief synopsis of the chapters and comments on their appropriateness in a basic course is therefore appropriate. Chapter 1 introduces the basic concepts to data mining and warehousing and its essentials. Chapter 2 covers the types of knowledge and learning concepts, which are essential to data mining techniques. Chapter 3 covers how to discover the knowledge hidden in the databases using various techniques. Chapter 4 deals with various types of data mining techniques and algorithms available. Chapter 5 covers various applications related to data mining techniques and real time usage of these techniques in various fields like business, commercial organizations, etc. Chapter 6 deals with the evaluation of data warehouse and need of the new design process for databases. Chapter 7 covers how to design the data warehouse using fact tables, dimension tables and schemas. Chapter 8 deals with partitioning strategy in software and hardware. Chapter 9 covers the data mart and meta data. Chapter 10 covers backup and recovery process. Chapter 11 deals with performance, tuning of data warehouse, challenges, benefits and new architecture of the data warehouse. This book also contains sufficient material to make up an advanced course on data mining and warehousing. Each and every chapter has exercise. Model question paper is also given. We conclude that, this book is the only book, which deals both data mining techniques and data warehousing concepts suited for the modern time.

Without such help, this book would indeed be poorer. We first of all record our gratitude to the authorities of Bharathiyar College of Engineering and Technology, Karaikal, whose efforts maintained the progress of our work and ultimately put us in the right path. Many experts made their contributions to the quality of writing by providing oversight and critiques in their special areas of interest. We particularly thank Dr. S.R. Rajagopalan, Ph.D., Retd. Scientist, N.A.L, Bangalore, for sparing his precious time in editing this book. We owe thanks to our colleagues and friends who have added to this book by providing us with their valuable suggestions. Such excellence as the book may have is owed in part to them, any errors are ours. We are also indebted to our publishers Messrs. New Age International (P) Ltd. for their tolerance of our many requests and especially for their commitment to this book and its authors. Once again we acknowledge our family members and wish them to know that our thanks are not merely “Proforma”, they are sincerely offered and well deserved. We particularly thank my graduate students for contributing a great deal to some of the original wording and editing. And finally, each of us wishes to “doff his hat” to the other for the unstinting efforts to make this book the best possible, for the willingness to accept the advice of the other, and for the faith in our joint effort. We began writing this book an year ago as good friends and we completed it as even better friends. S. Prabhu N.Venkatesan
