What Are Examples of Information Systems?

Examples of information systems include transaction processing systems, customer relationship systems, business intelligence systems and knowledge management systems. Successful organizations use information technology to collect and process data to manage business activities, revenue, customer service and decision-making.

Information technologies use software, hardware, data and procedures to process large amounts of information and to perform complex calculations. Transaction processing systems, such as online air ticket booking systems, collect data from users and generate an airline ticket and a bill. Customer relationship systems track customer activities, purchasing trends, product defects and customer inquiries. They allow customers to interact with companies for service, product feedback and problem resolutions. Business intelligence systems predict future sales patterns, summarize current costs and forecast revenues. Knowledge management systems analyze, organize and share knowledge with organization members for innovation and improved performance.
