Architecture Division

• “Plug Tools into a Framework”

  • Framework comes first, can add tools later

• Tools: plug and play

  • Components the user interacts with directly when doing SE
  • E.g. DFD Editor, generic Matrix Editor, Metamodeling tools
  • Whilst tools can use other tools’ services, mostly they use frameworks

• Frameworks: skeleton, MetaEngine

  • Relatively fixed infrastructure capabilities
  • E.g. support for processes, objects, user interfaces
  • Simplify tool construction by supplying commonly-needed facilities
