Hi, I'm afraid there is no way to connect to external databases.
Currently the only access you can have is either to the GAE big table-based datastore via various APIs (JPA, JDO, low level API, or third party such as Objectify/Twig/Slim3), or to external applications via an HTTP interface. There is a product in beta for SQL access to a GAE-hosted MySQL instance, but once again this won't allow access to externally hosted databases.
