To reiterate, composition models a "has-a" relationship between objects, as opposed to an "is-a" relationship which is typically done through inheritance or interface implementation. However, Christopher seems to be working with two different kinds of objects here: Singletons and business objects. How you handle the composition can depend on the kind of object you are dealing with and what they are meant to do. coldfusion frameworks java Tue, 17 Jun 2008 19:43:42 GMT http://www.dzone.com/links/87672.html danwilson 2008-06-17T19:43:42Z Christopher R contacted me through my contact form to ask about object composition.

The episode in question is called The Wizard of Evergreen Terrace. The basic plot of the episode is that Homer realizes that he hasn't done much in his life and decides to be an inventor. Obviously, many funny gags follow. The thing that prompted this blog entry was one of Homer's inventions. He called it the "Everything's ok alarm". Basically it beeps loudly every three seconds unless something isn't ok. flash-flex ria usability Wed, 26 Mar 2008 13:06:35 GMT http://www.dzone.com/links/72523.html danwilson 2008-03-26T13:06:35Z I happened upon a Simpson's episode the other day that, despite having nothing to do with User Experience, made me think of a common experience in web applications.
