"""Defines interface for DB access.
The underlying driver is loaded as a :class:`LazyPluggable`.
Functions in this module are imported into the nova.virt.baremetal.db
namespace. Call these functions from nova.virt.baremetal.db namespace, not
the nova.virt.baremetal.db.api namespace.
All functions in this module return objects that implement a dictionary-like
interface. Currently, many of these objects are sqlalchemy objects that
implement a dictionary interface. However, a future goal is to have all of
these objects be simple dictionaries.
**Related Flags**
:baremetal_db_backend: string to lookup in the list of LazyPluggable backends.
`sqlalchemy` is the only supported backend right now.
:[BAREMETAL] sql_connection: string specifying the sqlalchemy connection to
use, like: `sqlite:///var/lib/nova/nova.sqlite`.
