[Zope] I need advice

Hey guys: We are setting up a mysql database on linux for testing. However, I may be forced to go woth microsoft sqlserver. What Z da will I use for sqlserver. I searched the zope site but found little. This question is for sqlserver version 6.6 and 7.0 just to be safe. Is the Z OBDC da the one to use? I read it is win32 only so my zope would sit behind iis. Are there other Z da's to use? I did read the sybase should work with sqlserver 6.5? is this true? thanks cwj
