RELATIONSHIPS BETWEEN INFORMATION PROCESSES.
Data is collected, organised, analysed, stored, retrieved, processed, transmitted, received and displayed in virtually all information systems.
Data flows into the information system from an external source. The information system within the system performs its particular task and then the result gets outputted to an external entity known as a sink. It is common for an external entity to be both a source and a sink. Data stores are locations where data is permanently stored; such as files, databases or even physical items such as filing cabinets.
