Information Systems

Introducing theory and procedures necessary for the design and development of information systems, this book is geared for courses in information systems. Divided into three parts; part I introduces information systems theory and establishes that any information system may be thought of as a set of six building blocks; part II treats each of these building blocks separately; and part III treats systems development methodology: how to design and put the pieces together. The book has many examples, figures, questions, exercises, problems and case studies.
