What is a Computer Based Information System (CBIS)?
Alan Turing designed the electronic computer after a human computer
Computer = General Purpose Machine
In systems analysis and design the rules of behavior in the organization are transformed into automated rules (program code)
==> after being automated, a change in the behavior requires a change in the
Computer processes rules (if statements). Information systems are rules (patterns of behavior). Computer based information systems are automated rules (automated patterns of behavior).
Current Belief: Computer processes information like DNA or a simple organic cell.
Testing the current belief: Write the computer program for a tree.
