Key points

  • The purpose of an information system is to provide access to information
  • An information system must make data meaningful (meaningful data is known as information) by presenting it in a way that it can be understood
  • This can be as simple as labelling an item of text, to translating an MP3 file into sound waves
  • Information systems are designed to allow multi-user access to data. Databases will allow many people to read information at the same time, and even control writing of information to make sure two people will not overwrite each other’s data.
  • The features and functionality of an information system will be determined by its purpose. Good information systems provide just the right information in an accessible way – a website focussing on news, for example, should be designed with this in mind, rather than games or interactive elements.
