I've moved your question to the .NET Forum.
The .NET Articles section is reserved for "how-to" articles and other useful information and is not meant for questions. You should post your question in the .NET Forum section in the future to receive help with your problem. (Blue Menu: Forums -> .NET)
We do not normally answer such trivial questions (such a questions that you can very easily answer by googling or looking them up in a book)...but I'll get you pointed in the right direction.
Check out
how to use a database in your program and be sure to check out
the MSDN library. If you go to the top of the .NET Forum there are more recommendations on where to find good .Net resources in stick threads.
As for creating the database, I suggest attempting to design it on your own first and if you have problems post your question in the database forum that is dedicated to the database that you are using.
Cheers!
