An Information System is a system that gathers data and disseminates information with the sole purpose of providing information to its users.
The main object of an information system is to provide information to its users. Information systems vary according to the type of users who use the system.
“Information can be recorded as signs, or transmitted as signals. Information is any kind of event that affects the state of a dynamic system that can interpret the information.
Data can be described as unprocessed facts and figures. Plain collected data as raw facts cannot help in decision-making. However, data is the raw material that is organized, structured, and interpreted to create useful information systems.
Data is defined as ‘groups of non-random symbols in the form of text, images, voice representing quantities, action and objects'.
