Architecture
A platform-enabled web application exchanges data with plug-in applications. When designing a platform, it is necessary to determine what data is exposed by the platform and under what conditions. This exchange of data is fundamental to the design of a platform-enabled website. Designed correctly, the platform and the applications that extend it are loosely coupled, yet maintain a seamless look and feel.
A loosely coupled relationship between the platform and a plug-in application exists when:
- the platform does not depend on the plug-in application (i.e., the platform will still operate even if a plug-in is removed);
- plug-in applications can be added and removed easily;
- there is a well-defined interface for communication between the platform and the plug-in application;
- unexpected termination or errors in a plug-in application will not be detrimental to the platform;
- there are minimal expectations about the internal operation of each component (i.e., the platform and the plug-in application are black boxes).

Famous quotes containing the word architecture:
“Defaced ruins of architecture and statuary, like the wrinkles of decrepitude of a once beautiful woman, only make one regret that one did not see them when they were enchanting.”
—Horace Walpole (1717–1797)
“And when his hours are numbered, and the world
Is all his own, retiring, as he were not,
Leaves, when the sun appears, astonished Art
To mimic in slow structures, stone by stone,
Built in an age, the mad wind’s night-work,
The frolic architecture of the snow.”
—Ralph Waldo Emerson (1803–1882)
“It seems a fantastic paradox, but it is nevertheless a most important truth, that no architecture can be truly noble which is not imperfect.”
—John Ruskin (1819–1900)
