Hi,
I faced some difficulties on mapping my desired domain model to persistent object using OA. Then i found an article in the knowledge base, talking about wrap persistent object (generated by OA) to business object.
Is this the best practice to use for n-tier web development? What are the disadvantages of doing this?
Thanks,
Kevin

Hi Kevin,
Yes, we recommend that the persistent objects are not used in all layers of the application but only in the data access layer and in the layer that contains the business logic and handles the reading / writing of persistent objects. This way you get stronger separation of concerns and if necessary you can replace more easily the different layers of the application.
The disadvantage at the moment is that you have to write manually the additional wrapper objects. We will provide an option for automatic generation of such objects in one of the future releases.

Hi
If you could bump this feature (wrapper generator) to Q1 or an out of band release, then I would be pretty greatful. Right now for convenience we are literally passing iqueryable data within the UI and business tiers. It makes the system very flexible but im sure its not the best way to do things.

Hello Michael Josiah,
I am afraid that this functionality will not make it for the Q1 release. However, I hope that we will be able to provide it in one of the service packs before Q2.
Best wishes,
