Using an ORM like DevForce, do you recommend isolating it from the applications using a service bus or something?

We are in the process of choosing a way to isolate our .NET client applications from a SQLServer database and we are leaning toward the DevForce ORM.

This ORM is used for distributed applications and provides its own application server for handling clients requests.

However, I feel that the 开发者_Python百科client applications would be too tightly coupled to the ORM so I thought of using a service bus along with it (NServiceBus) or even a request/response service layer like Agatha.

Specifically, since we have .NET 2 applications and DevForce supports .NET4 we might have to do an isolation layer anyway...

Any thoughts on this?

I agree that shielding clients from that implementation is a good idea, but my first thought would have been interfaces rather than a service bus.
