  3. Information Processing • Set of activities done in a particular sequence to bring about a desired outcome • Processes include • Input –getting data • Output –information going out Structure/Processing Activity Information Data

  4. Manual Information System • Humans perform all activities of the processing activities. • E.g. • Finding a friends number in your directory • Library cards written up to loan a book

  5.

  7. Manual vs. AIS • Manual • Collecting • Collating • Analyzing • Presenting • Disseminating • AIS • Input • Processing • Output • Storage • Transmission

  8. Automated Information System • An automated information system is simply a system by which information is processed for collection and distribution through a series of automated processes. • The system often requires very little human interaction other than setup and maintenance. • The automated information system is often used to access information and send it out to individuals. Those using automated information systems include governments, libraries, and private businesses.

  9. Major Components of an AIS • Hardware • Software • Networks and Communication • People

  10. Activities • Input –data capture & data entry • What is involved in data capture? • Output • presenting & disseminating • Processing • Analyzing, sort, calculate, etc. • Storing • Retrieve • Transmission (communication)

  11. Assignment • Identify types of manual and automated information systems.
