Design Patterns

[Kishore Shewani]

While developing web applications design patterns really help in providing a standard architecture.
Can anyone explain what exactly is the meaning of :
> Value Objects,
> Data Objects,
> Support/Helper Classes
And the differences between them.
Why do we have value and data objects at the same time?

Here is link to the java blueprints catalog of design patterns. The link will also show example code based on the java pet store. I hope this will help answer some of the questions now and in the future you may have.

But, if you still have some detail questions on design patterns, see below.
A lot of these patterns as well as other OOAD issues are discussed in detail at the oo, patterns forum
I hope this helps.
