Designed for introductory (level 1) information systems units on computing courses this textbook covers the business contexts in which information systems are used and the types of information systems used. It considers the information technology available to implement such systems, their analysis and design, and their societal context. The topics are presented in short chapters that match the teaching year. Two case studies run throughout the book and lead onto project work where a small information system is implemented. An accompanying website features solutions for exercises, PowerPoint slides and more detailed instructions for the end of book project.
