How deeply does The Quick Python Book, Fourth Edition cover Hibernate session?

Explains setup, execution, commits, queries, inserts, updates, and deletes, without descending into session internals.

Hibernate session

As explained in The Quick Python Book, Fourth Edition

Session is a SQLAlchemy unit-of-work object that manages database interactions and transactional changes.

A SQLAlchemy Session is the unit-of-work object used to connect ORM operations to a database and manage transactional changes. Create an engine and table metadata, bind a sessionmaker to the engine, then instantiate a session. section 23.4.1

Use the session to perform database work:

Call session.commit() to save transactional changes. section 23.4.1

Insert and commit

After defining the people table and creating a session, build an insert object, execute it, and commit the change: session.execute(people_ins); session.commit(). Querying afterward returns the saved row.
