python - Best option for Google App Engine Datastore and external database?

Question

I need to get an App Engine app talking to and sharing data with an external database,

The best option i can come up with is outputting the external database data to an xml file and then processing this in my app engine app and storing it inside the datastore,

although the data being shared is sensitive data such as login details so outputting this to an xml file is not exactly a great idea, is it possible for the app engine app to directly query the database? or is there a secure option for using xml files?

oh and im using python/django and the external database will be hosted on another domain
