Developing a data access layer using ADO.Net and LINQ

I have a potential project where I would be working on developing the "Data Access Layer" of a reporting application using ADO.Net and LINQToSQL.

I have not specifically worked on a Data Access Layer project (middle tier), so I was wondering if any开发者_运维知识库one here could provide a sample / example / resource, where I can get an idea of what the project entails.

Hi take a look at this really good article:
