Can you explain why one to one is not advised? We use one-to-one in a
non-legacy system, generally for items which are optional. The other way we
could do this would be to represent the object as a many to many, which now
structures the data in a way that is inconsistent with how we use the data.

I'm seeing recommendations from NHProf/Ayende to do the following:
using(var session = sessionFactory.OpenSession())
using(var tx = session.BeginTransaction())
{
var post = session.Get(1);
// do something with post
tx.Commit();

I am reading through a book on NHibernate (NHIbernate in Action, Manning)

(which is what EntityBase does) it strongly discourages equality based on
database Id's:
Unfortunately, this solution has one huge problem: NHiberna
What about scenarios where a property performs some calculation. Imagine an
"Order" object and OrderTotal is a property so that it can be persisted.
Yet OrderTotal looks something like:

}
}

We have two databases, a SQL server database and another proprietary
database for storing our products in.
We want to store order information in the database. In the object world,
the Order has OrderItems. OrderItem is composed of a Product and a
Quantity. The problem is the Product information

I'm hearing and reading different thingsis unidirectional or
bidirectional the recommended way.
On certain scenarios I don't need to go unidirectional but then have a hard
time mapping but then see people say unidirectional is bad.
Which is it? Uni or Bi?

I have a user object and the user can have a number of wishlists.
Instead of having methods on user (ie. User.AddWishlist,
User.RemoveWishlist), I have a WishListManager which has these methods on
it.
Persistent entities include, WishList and WishList item, which relate back
to the user through t
oute.

What we want to do seems fairly trivial but am bumping into my limited
knowledge with NH.
We have a user (in the context of an eCommerce site). This user can have a
number of addresses (think an address book). For convenience the user can
also have a default addressId.
I have two tables...User
Props to you all who are on the NH team.
My question was definitely newbie-ish, however being new I am not always

Very nice and thank you.

We have a class "Money" which is used for obvious purposes. In the

we simply use an implicit operator, however NH is having trouble
