REST APIs with Flask and Python - Logging In and Retrieving Users from a Database

The video tutorial covers integrating SQLite with an API for user authentication. It begins with an overview of the current system using an in-memory database and transitions to setting up an SQLite database. The tutorial explains how to implement methods for retrieving user data from the database and refactors the code to replace in-memory storage with SQLite. Finally, it demonstrates testing the application using Postman to ensure the authentication process works correctly.
