  • Develop logical and physical systems designs from structured and UML analysis models.
  • Differentiate between a data driven design approach and an object driven design approach.
  • Select and use a recognised design methodology to meet specific system design requirements.
  • Explain the role and objectives of systems design in the systems development life cycle.
  • Evaluate the suitability of an input and output system.
  • Construct a usable user interface (HCI).
  • Apply the rules of normalization to a set of data attributes.
  • Understand and apply the principles of security, confidentiality and privacy
