Yes. From the SQLAlchemy docs: In the most general sense, the Session <http://docs.sqlalchemy.org/en/latest/orm/session_api.html#sqlalchemy.orm.session.Session> establishes all conversations with the database and represents a “holding zone” for all the objects which you’ve loaded or associated with it during its lifespan. It provides the entrypoint to acquire a Query <http://docs.sqlalchemy.org/en/latest/orm/query.html#sqlalchemy.orm.query.Query> object, which sends queries to the database using the Session <http://docs.sqlalchemy.org/en/latest/orm/session_api.html#sqlalchemy.orm.session.Session> object’s current database connection, populating result rows into objects that are then stored in the Session <http://docs.sqlalchemy.org/en/latest/orm/session_api.html#sqlalchemy.orm.session.Session>, inside a structure called the Identity Map <http://martinfowler.com/eaaCatalog/identityMap.html> - a data structure that maintains unique copies of each object, where “unique” means “only one object with a particular primary key”.
