With complete distribution applications which employ computer power wherever it is accessible and give information wherever it is necessary, everybody will in future be able to use inexpensive and efficient desktop technology. In future, owners and registered users will have access to information to avoid the need for expert systems developers and their complicated programming languages. Information will be captured at source and immediately made available in the future to authorized users.
