Which DB can used with Dascode for Datasource

I searched lot of sites for the name of db with iPhone webapp using Dashcode 开发者_JS百科but am not getting satisfactory results from any of sites.

I just want to know which database can used with iPhone webapp using Dashcode and how to do the connectivity for the same. Because as far I know that JavaScript is used as language over here so which db server can be used and how to connect to that db using Dashcode.

Dashcode uses JSON/XML for communicating with your application, because dashcode apps run in browser at client side. You need to serve JSON/XML data from you backend application. The application can be written in anything (Ruby on Rails, Python, Java, ASPX, etc.) and the application can connect to any database.

If you have paid Apple developer subscription (developer.apple.com) you have access to plenty of videos and documents also about Dashcode.
