Design Patterns / Architectures

Apologies in advance, I'm not 100% where to post this! Here goes.

Hey people. My new job role has basically given me the duty of proposing a new web based architecture for an Enterprise Application of ours, but I'm in need of some Design Patterns and Architectures to pitch to them and I'm a little lost.

Our company is all about booking office maintenance equipment so we'll be communicating with alot of external people, if that's of any help.

Any assistance from you guys would be absolutely delightful seeing how I have to get this in and pitched before Christmas :D

Thank you so much.

What do you know about J2EE - presuming this is the way you choose to go? If you have not yet, I'd recommend to google 'j2ee design patterns' - you will get a lot of websites describing the different design patterns to consider when designing a web architecture.

Fantastic, thanks.
