Re: [google-appengine] how to use a database

[Barry Hunter]

Well AppEngine comes with its own Database - the Datastore. The
datastore is proprietary to Google, and develope especially for
AppEngine. Its accessed by its own dedicated API - implemented by the
platform itself.
https://developers.google.com/appengine/docs/python/datastore/overview
https://developers.google.com/appengine/docs/java/datastore/overview
How exactly it works, doesn't matter - Google take care of that - you
just need to use the APIs.


Or apps can access Google Cloud SQL instances, which are mysql
databases, managed by Google. Again the platform provides APIs to
access them.
https://developers.google.com/cloud-sql/

Other than that an AppEngine could access any remotely hosted database
- provided there is a HTTP/S interface to it.
