Difference between Physical and Logical

'Physical' means that we document the system as it appears in the 'real world', while 'logical' means what the system actually does. Our system development project, therefore, has four stages in its development:

  1. Current Physical
  1. Current Logical
  1. Required Logical
  1. Required Physical

(Note that this course only covers the current system.)
