Think about the possibilities of a component in the data access layer (DAL) of your application that didn't care what .NET Data Provider you were using. It could work just as easily with the SQL Server Data Provider or the OleDb Data Provider, or any other potential .NET Data Providers that could surface in the future. A DAL component that you could use against an Access 2000 database in development, and against a SQL Server database in production. In this tutorial I will show you how to build a universal data access component, and explain how the .NET Data Providers enable this. The downloadable sample code is in both Visual Basic.NET and C#.
