    Component Definition Summary

    What is a component?

    Definition of Component

    The definition of component is:

    A physical replacable part of a larger whole. A physical entity of a system. Typically providing behavior via interfaces and requiring interfaces to function.

    Examples are a software application component like a parser component, a machine component or a vehicle component like an engine.

    A component performs tasks, called behavior, and with that takes care of one or more functions for a system it is part of.

    A module is often the logical counter part (element) of one or more components. Preferrable, to increase replacability, the interfaces conform to open standards.

    The shape for component in Dragon1 is a square with interface handles:

    'Component' has important relationships with 'Entity', 'Function', 'Service', 'Interface'.
