ACCOUNTING INFORMATION SYSTEMS provides thorough and up-to-date coverage of accounting information systems and related technologies. It features an early presentation of transaction cycles, as well as an emphasis on ethics, fraud, and the modern manufacturing environment. The book focuses on the needs and responsibilities of accountants as end users of systems; systems designers; and auditors. This edition provides complete integrated coverage of Sarbanes-Oxley as it affects internal controls and other relevant topics affected by this legislation, as well as reorganized discussion of transaction cycles that make the balance between manual- and computer-based systems more apparent.
