I have just started learning Windows 8 Store app programming and came around a question. Does Windows 8 Store apps support MS Access database ?
If not then which all database does it support?
Depends on your definition of support, you could create a WCF service that allows you to access your data from MS Access, see the link below for how to access WCF Services in a Windows store app.

But if you don't want to be tied to MS Access or want to use a database as local storage for the application then here is an article discussing the various options you have for data storage.
