The new application got a draft already. Most of the core functions got a draft design in it. I think that I can design one more function and its database schema tomorrow. Yes...this is good..

and Amazing~~~

I tried to module all the thing in a class diagram and I found out I don't need to implement all the classes in the same language or in OO. It is because the class diagram is just made us to have a clear mind in the structure of web application. But I am not saying I can't implement those completely in OO. But after consideration the current web design philosophy and technology, it maybe better not to implement all the thing in a OO language ( at least the layout should be used with html, dom, javascript and AJAX while the control layer should be used with Server side script language ).

In the past ( I mean when I was still taking my degree ), we all were asked to design the whole class diagram, but until now, I realized that I dun need to implement them with the same language or exactly some of them in OO. I just think that this is a tool to assist us to make a big picture clear.
