5"""Interfaces to the SQL-based storage backends for mlos_bench using `SQLAlchemy 

6<https://www.sqlalchemy.org/>`_. 

7 

8In general any SQL system supported by SQLAlchemy can be used, but the default is a 

9local SQLite instance. 

10 

11Although the schema is defined (and printable) by the 

12:py:mod:`mlos_bench.storage.sql.schema` module so direct queries are possible, users 

13are expected to interact with the data using the 

14:py:class:`~mlos_bench.storage.sql.experiment_data.ExperimentSqlData` and 

15:py:class:`~mlos_bench.storage.sql.trial_data.TrialSqlData` interfaces, which can be 

16obtained from the initial :py:class:`.SqlStorage` instance obtained by 

17:py:func:`mlos_bench.storage.storage_factory.from_config`.
