Interesting video, as always Anders is enlightening, but Chris McConnell is a WinFS hater
Just because a schema doesn't satisfy everybody, doesn't mean schemas are a bad idea! You might not be able to create a schema that satisfies everyone, but it is an order of magnitude simplier to create a schema that satisfies one organization or describes
how a particular common application is modelled!
And the performance argument about WinFS not being able to perform? Because it is rigid and normalized? Sounds like FUD to me...
