The separation of a system's internal structure, behaviour and external presentation is inherent in application domains:
- GUI Applications: Model-View-Controller
- structure = Model, behaviour = Controller, presentation = View
- Web Applications: HTML, CSS, Javascript
- structure = HTML, behaviour = Javascript, presentation = CSS
- HtDW Applications: Data definitions, Function definitions,
- structure = data, behaviour = function, presentation = missing
Structure is internal.
Presentation is external.
