Vista Tutorial - Will winfs be used instead of database (in some certain scenarios)?

Hi,



I just installed WinFS beta and took a quick look at those samples. Since I
have been developing .NET smart client application for a couple of years, I
can imagine WinFS can be used as a local storage for offline data, and I
assume in many scenarios that'll be a better choice than MSDE. My question
is, what about the server side? Currently most business applications use
relational databases to store data, will it be possible that some of (at
what percentage?) those applications will use WinFS on the server side
instead to store data like purchase order item etc? (If the answer is yes)
If something needs to be used to bridge the gap between database and WinFS,
will it be ObjectSpace?



Thanks

Kent

I suspect writing a WinFS sync adapter to sync between a local WinFS store
and an existing remote relational database will be a popular option.

(From business application point of view -)
Will it be practical to use WinFS as object persistence layer on the server
side?
Or it's just positioned to be the local cache on client side?

Thanks

Perhaps, but there is word of a "Entity Framework" coming in ADO.Net 3.0
that would more likely be targeted at that.

It does seem that is the main focus of WinFS at this point.

PS: I dream of a day when WinFS replaces Sharepoint, Exchange, SQL Server,
and file shares, both server side and client side.

It seems that "Entity Framework" and ADO.NET 3.0 related documents are gone
from all websites... ;-)
Is "Entity Framework" related to ObjectSpace?

Hi-

As has been pointed up, we expect synchronization between local stores and
remote stores a common scenario. Having said that, we do expect to
eventually release a "server" version of WinFS. It will not solely be a
client side technology. If you think of the local WinFS storage as a local
file system, you can think about the server as a "file server" for WinFS
data.

But, we have not released any details about the WinFS server.

So, will you talk about this WinFS server thing in the coming TechEd? ;-)
Back to the original question - what I'm interested in is that if WinFS
(server) will play a role as business application server side data storage
or persistence layer...
But according to what Chris said, it sounds like ASP.NET 3.0 and 'entity
framework' would be a better candidate for that role...

Hopefully we can have more detail about all those stuffs after TechEd...

Thanks
Kent
