This is a very short introduction to a fascinating world of information systems, with a special focus on health information systems. The digitisation of information and society is an ongoing effort, and it can be illustrated by the common Vision for eHealth 2025, endorsed by the Government and the Swedish Association of Local Authorities and Regions (SKL):

In 2025, Sweden will be best in the world at using the opportunities offered by digitisation and eHealth to make it easier for people to achieve good and equal health and welfare, and to develop and strengthen their own resources for increased independence and participation in the life of society.
