 The starter code includes a `dataAccess.DataAccessException`. This exception should be thrown by data access methods that could fail. If a method call fails, it should throw a `DataAccessException`. For example, the `DataAccessException` is thrown if a user attempts to update a non-existent game. If you like, feel free to create subclasses of DataAccessException that represent more specific errors relating to data access.

+> In Phases 3-6, you may find it helpful to create more exception classes besides DataAccessException.
