We have an ASP.NET MVC application. Is it correct to think of the models as the "entities" in the system?

Hi! Normally rails loads data with a :select => "*" from the database. I know I could change this. But I'd like to go another way: always only select "id" and load the attributes automatically later on when they are needed. Example: accessing user.description should if it's been loaded yet. if not, trigger a "SELECT description FROM us...

I'm trying to build VERY basic model->controller->view structure with CodeIgniter. I'd rather use models (and model functions, more importantly) and controllers than executing queries within each view.
