@Fabio,
Sometimes we have to integrate new systems (completely new data model) with
a system that makes use of legacy data model. Given this situation, is it
possible to mix ConfORM with XML-mapping ?

In NHibernate, a class name can be anything you want since acceptable to C#
therefore it doesn´t have to follow the tables names.
For example, you could create a class named as OurCompanyXItem where X is

Well,
I dont see a reasons for why not use HQL in this case.
If I am not mistaken this query below is actually an HQL query.
I have tested this query with different classes here and it seems to have
worked.
select s.Id, s.Name, sum(q.PointsObtained), sum(q.TotalPoints)
from Student s
join s.Quest
Last time I had this problem was due to differences in column names such as
idAddress and idaddress. I suggest to check if all column names are
following the same name convention.
You can use a regular expression in *.hbm.xml such as that:

Hi epitka,
One complementary way to minimize this problem is to create views in the new
database.
These views can map the old tables at the same time that it makes use of
data model formatting from the new database and thus NHibernate don´t need
to do too much "gymnastics".

Hi Reggieboy,
Are you sure it is NHibernate who is slowing your app down ?
You need a very large number of entities in order to feel it.
Just to give you an idea I have a Winform application with almost 1000
entities but no sensitive slow down in the initialization or any other part.

Hello Fernando,
Generally speaking:
*.hbm.xml :
- Best option when you need flexibility between data model and object model.
- Usually also best for legacy data models
*Fluent Automapper:
- Best option when data model will follow the object model
- Best option if you need speed and you dont want

Hello,
Tipically I would create some DAO class *NHibernateTitleDAO *with a method
like *GetTitles( ) : IList . The HQL would be implemented
inside populating the list of DTOs.

It is a matter of using the right naming strategy. You can tell NHibernate
to use your private field for "set" and your public property for "get".
In order to to do it you must use the right access strategy.

Documentation of a not-so-trivial tool like NHibernate is definitely an

Hi,
I can think of two options for your problem:

Personally I would take option 1 since it is simpler to map

Documents can be added, removed or altered in the Person object only in *

it is one table for the entire hierarchy or one table per class ?
