"Object-orientation is a new technology based on objects
and classes. It presently represents the best methodological
framework for software engineering and its pragmatics provides the
foundation for a systematic engineering discipline. By providing
first class support for the objects and classes of objects of an
application domain, the object-oriented paradigm precepts better
modeling and implementation of systems. Objects provide a canonical
focus throughout analysis, design, and implementation by
emphasizing the state, behavior, and interaction of objects in its
models, providing the desirable property of seamlessness between
activities." (Robert John Hathaway)
"Object-oriented languages and systems are a developing
technology. There can be no agreement on the set of features and
mechanisms that belong in an object-oriented language since
the paradigm is far too general to be tied down. We can expect to
see new ideas in object-oriented systems for many years to
come." (Oscar Nierstrasz)
"Component-oriented programming has been described as
the natural extension of object-oriented programming to the
realm of independently extensible systems.
Component-oriented programming aims at producing software
components for a component market and for late composition.
Composers are third parties, possibly the end user, who are not
able or willing to change components. This requires standards to
allow independently created components to interoperate, and
specifications that put the composer into the position to decide
what can be composed under which conditions." (Clemens Szyperski /
Wolfgang Weck)
