component based software engineering
Component-based software engineering
  • How do you define a “Component”?
  • How do you define “Component-based software engineering”?

Component-Based Software Engineering

Dr R Bahsoon

what is a component
What is a Component?
  • Several definitions of a component in literature, however everyone agrees that a component is a piece of software… But this requires clarification!

Component-Based Software Engineering

Dr R Bahsoon

what is a component1
What is a Component?
  • Components provide a service without regard to where the component is executing or its programming language
    • A component is an independent executable entity that can be made up of one or more executable objects
    • The component interface is published and all interactions are through the published interface

Component-Based Software Engineering

Dr R Bahsoon

what is a component2
What is a Component?
  • There are many other definitions of components:
    • Consideration of CBSE from different viewpoints and focus on different aspects of software engineering
      • Design phase: components as reusable design parts
      • Architecture phase: (e.g. UML components; ADL component)
      • Implementation phase: components confirmed to a specific component model
      • At run time could be binary packages, distributed components
      • Business aspects (business components, service components, COTS components)

assessment
Assessment
  • Assessment
    • 1.5 hr examination (80%)
      • Choice
      • Compulsory questions: concepts, processes, UML modelling…
      • Reflection questions: presentations-related…
    • Continuous assessment (20%)
      • Group presentations, discussion, and reflection on some advanced CBSE topics
        • Presentation schedule & topics will be posted soon
        • Peer and self assessment (friendly and supportive “shepherding” style)
        • Workshop-like style: interactive
      • Group modelling exercise – due by the end of the term
        • Courtesy face-to-face feedback providing training for your examination
      • “Small” discussion/reading exercises
  • Resit (where allowed) by examination only with the continuous assessment marks carried forward
