Understand what you are saying that vb2008 is not the ideal way to do this but can I just ask would you even try to make a class model of the system I have described or would you just code the various forms.

Question
oop and relational databases
Hi guys
This is just a general question, in vb2008 I am trying to model an application which connects to a relational database and displays, updates and deletes data in a datagridview, obviously I would like to make the application as object oriented as possible, what kind of class structure do you think I should use IE do you think I should have a class for every table in the database, with the properties of the class being the fields of the database tables, I have thought about this approach but there seems no point as the fields in the tables will not need to be manipulated they will just be updated and deleted, it will be interesting to hear your thoughts on this.
Regards

I, personally, don't prefer the custom class model approach, because it's a lot of work, and ADO.NET is perfectly suited for the task. If you are really interested in that approach, there is an excellent book written by Deborah Kurata named "Doing Objects in Visual Basic 2005" (you'll have to see if there is a 2008 version).
Here's a review I wrote about this book at Amazon.com:

Also, take a look at this article I wrote at The Code Project, it's titled "XML Database Demo". In this short demo you are walked through creating a strongly-type DataSet, with DataTables. This should at least familiarize you with it, although it can be even further simplified when working with Databases.

Create a new project in VS 2008.
Connect to a DataSource
Data menu | Add New DataSource
Select Database
Click New Connection, configure, close
Click next all the way through
Choose the Database objects (tables/stored procedures)
Click Finish
Automatically adds a Strongly-Typed DataSet to your program.
I think you need to get deep understanding of database accessing in .net framework specially using Visual Basic.NET
ADO.Net consists of a powerful tools and classes that handle data

I totally recommend just using ADO.NET: DataSets and DataTables. They are completely designed for that. They can completely model your database, with relationships and everything.
