ORM White Paper

October 7th, 2008

The NHibernate community has a very interesting article presenting several ORM concepts on their google groups page.

I found it particularly useful for understanding id generators, what are the available strategies and how to choose the best one. For example, we have a batch job that inserts a lot of objects and it takes about 35 minutes to perform using a “native” generator (we’re using MySQL). We changed to a hilo generator and it only took 25 minutes. Quite an improvement.
