Graffiti Beta 1 used Access as the primary way it stored data. SQL Server was also an option, but Access gave us an awesome copy/deploy story.
Today we’re announcing that Graffiti version 1.0 will use VistaDB as the primary database, not Microsoft Access.
I posted a few of the reasons why we chose VistaDB but there is another reason too. But more on that later =)
Mono Support
MySQL Support 
Trying to overtake WordPress with some very smart moves.
Will the express edition support VistaDB?
@Paperino, Yes
Will there be migration support from Access to VistaDB in v1? I wouldn’t want to create a bunch of settings and posts now and have to redo them all later… Thanks.
VistaDB has a Data Migration Wizard that does an excellent job of migrating an Access database to a VistaDB data file. I have done that migration many times now and have never had a hiccup.
