• Create and persist a schema.
• Create and save your first data model.

• Engine: a Python object that translates SQL to Python and vice-versa.
• Session: a Python object that uses an engine to allow us to programmatically interact with a database.
• Transaction: a strategy for executing database statements such that the group succeeds or fails as a unit.
• Migration: the process of moving data from one or more databases to one or more target databases.

This session is designed to be a code-along. There is a GitHub repo to clone down with branches to match different checkpoints along the way. If you run into errors before we move from one section to the next, please checkout the next checkpoint, but share those issues with me or another member of the curriculum team and we can address them after the session ends.

Clone that repo down now and run pipenv install && pipenv shell to start up your virtual environment.
