The App Engine datastore is schemaless. The closest thing to a table in a relational database is the kind. Each kind holds entities (records) all of which have attributes (fields). It is important to note that the entities of a given kind do not need to have the same attributes. See the datastore documentation for more information.

When writing to the App Engine datastore you do not create a table / kind in advance, instead you simply create the entity (record) of a given kind you'd like to store, and tell App Engine to store it. See here for a short example.

If you would like to use a relational database with App Engine, use Google Cloud SQL (essentially a MySQL database co-located with your App Engine application).
