I've used the repository pattern for years and find that it works well, but
as systems grow I find that changes to your repositories' interfaces can be
a bit of a pain. As such I've started moving more towards separating things
into commands and queries (I'm not talking about CQRS!) and I think that
the Enhanced Query Object that Fabio describes is a great approach to
reading data.

I think Dao and Repository are overrated pattern...
But i don't like to mix my nhibernate stuff with a webform for instance..
so i think the best approach is described by fabio here:
http://fabiomaulo.blogspot.com/2010/07/enhanced-query-object.html
the idea is that you have one class for this specific querying thing..
you test the query against the database, and you test your webform
against a mocked IQuerySomething
I've sent this same mail to the list like 25 times this year.... sorry

No answers. Mmmhh.
I mean: do you use in your programs the GenericDAO (eg var
dataSource = (new someEntityDAO()).GetRightEntities())?
Or do you prefer to directly write in your (Web)Forms code like:
var dataSource = CurrentSession.CreateQuery("from someEntity e
where...");
Thanks again,
marcello.
