And So It Begins Again

Hi All. Just wanted to say a big thanks for all the help you gave me during my last assignment. I happy to say, that with your help, I made an 86% on it.
Was wondering if you could point me in the right direction for the following, before I start attempting the coding.
1. Able to query 3 different questions to a MS Access relational database, containing 2 tables. Using a single class and the main method continually looping. (have a feeling that I will be loopy by the end of this *grin*).
2.Implementing business objects in a three-tier architecture (three-layer architecture) to access a database.
Thanks in advance for your help.
Cheers
Sue

heyas,
this question is probably more suited to the jdbc forum:
http://www.coderanch.com/forums/f-3/JDBC
but just in case you are new to the concept of jdbc, ill give you a quick run down.
basically on a windows system you can create what is called an ODBC
Control Panel >> Administrative tools >> Data Sorces (ODBC)
from there, you can add a file (in your instance a MS Access file) and once there, using third party components (such as java) we may view and manipulate such files.
a small example is reading from an excel file, although trivial, it shows you the basics of quiering a specific table, from a specific odbc..

from the code sample obviously 'ShowCodes' is the name of the odbc.. and once result set 'rs' is defined, we may call queries like:

which returns the column values under the heading/title 'state'
a helpful tutorial on MS ACCESS access with jdbc is
http://home-1.worldonline.nl/~bmc88/java/jdbc/
that should get you started
hope this helps somewhat

As suggested, for JDBC-related questions, the JDBC forum is a good place to ask them.
For asking about system design concepts, the OO, Patterns, UML and Refactoring forum is a good place to go.
For an easy introduction to JDBC, I suggest following the JDBC section of assignments in the JavaRanch Cattle Drive. Just click on "Assignment JDBC-1", and follow along. That's how I learned it.

Thanks guys, shall take your hints, clues and comments on board.
Once I'm ready to start firing questions about my coding, I shall go to the JDBC forum.
Cheers
