One of the most important uses of computers is (as an aid to managers) to provide up-to-date information to efficiently run their organizations. Of the total number of computers installed in the world today, over eighty percent are used in organizations for management information systems. It is thus very important for all students of management, commerce and computer science to know how to design computer-based information systems to aid management. This introductory text gives a lucid, self-contained presentation to students on how to analyse and design information systems for use by managers. Information Systems Analysis and Design (also known as System Analysis and Design) is a compulsory subject for MCA, BCA, B.Com. and B.E. students of Computer Science and Information Technology. This book covers the syllabus of this course and that of the DOEACC (Level A) examination. Thoroughly classroom tested and evolved out of twenty years of teaching Information Systems Design course at IIT Kanpur and IISc., Bangalore, this book presents real Indian examples. In this third edition every chapter has been updated, besides the addition of a new chapter on Use Case Method to reflect the rapid changes taking place in designing information systems. This book has been used to prepare learning material for the course Systems Analysis and Design for the National Programme for Technology Enhanced Learning of the Ministry of Human Resource Development, Government of India. The author has delivered 40 lectures on this topic which are available on YouTube. Besides, the book also contains supplementary materials such as PPTs and objective questions which are available on www.phindia.com/rajaraman_ADIS. Key Features • Covers comprehensively systems analysis and design. • Discusses object-oriented modelling of information systems. • A chapter on Electronic Commerce is unique to this book. • Presents a detailed case study of a complete information system. • Includes supplementary web material.
