Local database support Vender

I am just new in Flex/ARI development.

I Want to used local machine database in my one ARI (Desktop) Application,

So which database vender are available for local database support Windows OS, like SQlite....etc . Which one is best and faster for big databases.

Also its very good if their is no any driver, software do not need to install on client machine for database.

The only DB which AIR supports natively is SQLLite. It means AIR runtime has built in SQLLite instance.
