  • Chapter 9 addresses the oldest type of information system used in business – transaction processing systems – and its latest evolution, enterprise resource planning systems. All organizations have manual and automated transaction processing systems. These are key systems for businesses since they perform routine business activities, process key business activities and maintain records about them. Although they do not themselves explicitly support decision-making, transaction processing systems also collect and update data used by many other business information systems, such as management information systems or decision support systems. After studying chapter 9, you should be able to address the learning objectives described in the next 2 slides.
