This book is designed to give a broad overview of object oriented analysis, modeling and design. The modern trends of object models have been dealt from basic principles and terminologies in easily understandable English language so as to enable the reader to understand with minimal effort. The application case studies included is the strong feature of the book. This book would serve ideal for B.E.. B.Tech., B.S., B.Sc, B.C.A., undergraduate students of Computer Science and Engineering, Information Technology, Electronics and Communication Engineering who wish to take up projects on object modeling and software engineering. Students pursuing postgraduate course in Science and Engineering, M.E., M.Tech., M.S., M.Sc., M.C.A. students will find this book useful for their projects. Research Scholars working in the area of software engineering will find this book as a handy reference guide for their M.Phil., Ph.D. D.Sc., D, Litt., and other post-doctoral research works. Software Engineers involved in IT and ITES sector specifically on object oriented modeling and software engineering would find this book as a useful resource.
