Hi everybody,
I just want to know that do we really know inside out all the pattern in presentation tier,business tier and integration tier.
We use only few of the common pattern such as Data transfer Object,Session Facade,Data Access OBject.
I went to book site and found the chart which showing all patterns.
so do we really need to know all ?

Welcome to the 'ranch, Priya.
No, we don't need to know all patterns inside out. We only need to know enough of the patterns that could be useful "right now" in order to make a decision of using/not using the pattern (or which pattern to choose if there are several good candidates).
You could learn the Core J2EE Patterns by heart. You couldn't learn all design patterns by heart. That is why patterns are documented in a standard way simplifying the discovery of suitable patterns based on a given problem, a situation you want to get out of.

It is good to have a general idea of patterns available so whenever you need to apply one or have a hunch that this-might-be-a-well-documented-pattern you can lookup for the details

I think I can agree with Bushan, that if you dont have a general overview it could be too late for you and you end up doing things in the wrong way. I am certainly a culprit of such crime, having done my app and now re-doing it. I feel I need to stop read up on Patterns and then continue. Lets see if I can get it past the management though.
