    <p>I dig a lot of things about the <strong>DDD approach</strong> (Ubiquitous language, Aggregates, Repositories, etc.) and I think that, contrary to what I read a lot, entities should have behavior rather then being agnostic. All examples I see tend to present entities with <strong>virtual automatic properties</strong> and an <strong>empty constructor</strong> (protected or worst, public) and that's it. I consider this kind of objects more like DTOs then entities.</p> <p>I'm in the process of <strong>creating a framework</strong> with its specific API and I don't want to be <strong>tied to an ORM</strong>. So I built the domain first (without thinking of persistence) and now I would like to use NHibernate as persistence tool so I added a new project to my current solution to help ensure that my model isn't altered to support NHibernate. This project should be an implementation of the abstract repositories that live inside my domain. And now the difficulties arise.</p> <p>Since <strong>it is my first time with NHibernate</strong> (I'm also trying Fluent Nhibernate but it seems even more restricting) I would like to know :</p> <ol> <li>Is it possible to use NHibernate without altering a DDD model that is part of a framework</li> <li>The things (constraints) that are necessary for NHibernate to work as expected and efficiently (virtual properties, empty constructors, etc.) I think this list would be helpful to a lot of people who are starting to learn NHibernate.</li> </ol> <p>Please keep in mind that I'm building a framework so the <a href="http://en.wikipedia.org/wiki/Open/closed_principle" rel="nofollow noreferrer">Open/Closed Principle</a> is very important for me.</p> <p>P.S.: Sorry if my english is not good, I'm from Montreal and I speak french.</p> <p><strong>Edit 1:</strong> Here is one problem I have with NHibernate now - <a href="https://stackoverflow.com/questions/1516752/how-to-map-type-with-fluent-nhibernate">How to map Type with Nhibernate (and Fluent NHibernate)</a></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
