this might be good, didn't really read it just glanced quickly at it http://www.javaworld.com/jw-03-2000/jw-03-xmlsax.html .
But for more information try this.

That's a very old article, well and truely overtaken by events.

Those requirements are extremely vague and silly btw, impossible for me to see what you're saying you need to do and I severely doubt you understand it yourself.
It makes no sense at all.

look at what I said, . Note keywords might, and glanced over it quickly. Just trying to help out the google impaired. TY

You might want to start with some basic Java tutorials first.
Then learn something about JDBC, ORM frameworks, XML and how to generate it and parse it, and maybe then start thinking about combining all that knowledge.

Noone's going to do it all for you. Not only is that not the way it's done (you should do your own work) but also the topic is WAY too broad and your questions way too vague.
