Subject Re: Deprecating the DAO framework?
Date Sun, 29 Oct 2006 03:43:42 GMT
I agree with Jeff.

I think it is also important to note that the DAO framework is not
going to vanish, it will still be around for people to use, just not
as actively supported, and with little or no new development on
it...which is not much different than today.
