This blog talks about OpenERP, an OpenERP business application trying to manage an enterprise in an easier and powerful. I will try to explain how difficult it is to develop with OpenERP due to the bugs and the database model made by Tiny. Because I'm impartial I will also explain some good features.
If you are going for the other direction (other than Django)I would really recommend tryton and keep the hell away of openerp. Tryton is really open source. openerp is just like compiere, openbenbravo and many others: "Was truly open source" than, came the money!!
We made the change a while ago. I took a lot of work. Spare yourself this trouble. Go Tryton!
