Advice on data layer for reporting application

Question

Hi There

I have been tasked with developing a reporting application and could use some advice. I usually work on business applications and would always choose an ORM for my data layer.

The reporting app will not update or insert any data and the data is reams of counters which is not very meaningful so I am thinking ORM is not the best way forward.

The application will be written in C# with a Sql Server database.

I was thinking that datareaders but I don't really like the idea of developing a data layer from scratch.

Does anyone have any advice or opinions?
