I have racked my brains on this . This is the place where I got the best advice. So I decided to place it here. I've attached a document showing my idea of creating it.

It would be a many-users-using-changing-data-at-a-time kind of application with some administrative control. This makes it 2nd incomplete activity I have on my projects list.

How do I go @ it?
What components / softwares are required?
How to go @ developing it?
Please

Any books or websites suggestions are most welcome. Since this is what I do in my free time...this also does not have impending Deadlines.
