UML

• Definition
• The UML is Visual Language(meaning a drawing
  notation with semantics) used to create models of
  program.

POST System

• The POST system should be able to
• process sales
• handle payments
• inventory quantities should be updated

MATE Concepts and Architecture

• Multimedia assisted teaching environment
• Helps both teachers and students
• transfer knowledge and experience in systems
  analysis and design
• with the use of multimedia

14
MATE Concepts and Architecture

• Three activities
• Authoring
• creation of multimedia teaching components
• problem descriptions, solutions
• Delivery
• teaching and assessment material by a presenter
• Reception
• Active learning
• Evaluation

MATE from Students Perspective

• MATE supports a student in the process of
• 1.Learning
• creating own solutions with some feedback
• 2.Gaining experience
• by comparing their solutions to those of the
  similar problems
• 3.Scavenging
• browsing existing
• problem descriptions, problem solutions,
• design-patterns and design-rationale.

Select Controller pattern

• Based on the Controller pattern, four classes are
  candidates to handle this system event
• POST, Store, BuyItemsHandler, and Cashier.

22
Correct Choice
23
System feedback

• For each selection the student gets an immediate
  feedback in the feedback

24
Conclusions

• Work on case studies in their own time ,
  self-directed study and at their own pace
• Have ability to SAD.
