Thanks for that Tom, it makes more sense now. But what's this with TO's being an object only containing properties? I thought that was a bean? So for instants I'd have a bean that containing only getters and setters, nothing more, is that a TO, or is a TO more like an active record that represents a row of table data?

And how should they be applied within an application. A Facade is an interface that abstracts away from you the (complicated) process of using or creating something. A Service does a similar job, but is generally intended to be invoked by a remote client. It should only return TOs. > I've got a good grasp of the other terns like Factory, Bean, DAO, Gateway. > I'm also curious as to what a TO class is, I've never written one, is that > even a class? Or a bean? Are classes and beans the same thing? :-D A Transfer Object is just a class (object) with only properties - no methods. Their used for transferring results about in an agnostic manner.
