Different database for GAE

How to use another database for Google App engine than the datastore. And if it could be possible to access it wi开发者_Python百科th php(quercus).

Not in practical terms. Datastore is the only supported database at the moment.

You could have a database on another server and access it via RPC (REST, WebService), but this would not be an integrated approach and would add more work to the project. For example you could set up a MySql server somewhere and use phprestsql to setup a REST interface and then acces it from GAE.

i am also looking for same. I want to host my java web application on GAE and databse on different Server(Godaddy). Google data store is free for only 6 months, So i would like to use database of different hosting(goDaddy). So is it possibe??

I am able to use database of my hosting(goDaddy) from my local system but when i upload my application to GAE that it doesn't work. I know it is possible in case of other servers but what about GAE.
