enterprise analysis & design using UML

Delegates will learn
  • How to model business processes with process models and activity diagrams
  • How to determine the system scope with use case models, conceptual class models and state diagrams
  • How to formalise use cases with activity diagram storyboards
  • How to design re-usable components
  • How to design the internal behaviour of the use cases with interaction diagrams
  • How to refine the design with the effective use of OO heuristics, patterns, aggregation and generalisation
  • How frameworks can resolve common business problems.
Target Audience
  • Business Analysts wishing to know more about OO based definition & design
  • Designers and analyst/programmers who are moving to an OO environment
  • Those wishing to standardise on UML as their design specification model
  • Those needing a visual, round-trip engineering method
Style

This is an intensive 5-day non-residential course presenting design techniques from a practical perspective and using a structured approach based on UML supported by Design Patterns and Frameworks.  An live case study is used to help delegates practice the skills learned on the course.
