Python DB API 2.0

PostgreSQL is not the only relational database and of course it is not the only one you can use with Python. There is an API in Python that is designed to unify the way applications work with databases. It is called the Python Database API. By the time this book was written, it already had the second specification, defined in the Python Enhancement Proposal (PEP) 249. The specification of the Python DB API 2.0 is available at https://www.python.org/dev/peps/pep-0249/.

The API defines the following objects that are used when connecting to a database and interacting with it:

connection: This implements the logic of connecting to the database server, authenticating and managing transactions. A connection is created by calling the connect() function with a number of parameters that can differ depending on the database and the driver that is used.
