A session will try to automatically create the database if it doesn't exist. It will also create or update the database schema for any persistent classes currently being used.
A session will automatically create or update the database schema for the persistent classes currently being used. If the database doesn't exist, it won't be created by a session.
A session will not automatically create the database or update the database schema. The database schema is still queried and checked to match the currently used persistent class metadata.
A session will never query the database for schema to validate against persistent class metadata. This will suppress the SchemaCorrectionNeededException, but a database error may occur during data operations if the schema is not compatible with run-time persistent classes metadata.
