An information system is defined as a set of interrelated components that collect, process, store, and disseminate data and information to meet an objective. It involves input of raw data, processing to convert data into useful outputs, outputs in the form of documents and reports, and feedback to make changes to inputs or processing. A computer-based information system is a single set of hardware, software, databases, telecommunications, people, and procedures configured to collect, manipulate, store, and process data into information.
