Simkin & Norman's 12^th Edition of Concepts of Accounting Information Systems builds upon previous issues with more in-depth focus on topical issues essential to accountants such as Sarbanes-Oxley, Cobit Version 4, XBRL, and of risk and governance in a much more concise, user-friendly way. More Case in Point sections highlight how the concepts are applied in the field and additional multiple choice questions have been added at the end of the chapters to help reinforce the material. An enhanced and updated database chapter also provides hands-on instruction in Microsoft Access.
