Overview

Unlock the power of data in your applications with this foundational guide to SQL and PostgreSQL. Designed for developers, this codelab bridges the gap between building APIs and managing the data that powers them. You'll start by installing PostgreSQL, a robust and open-source relational database, on your system. Then, you'll dive into the essentials of Structured Query Language (SQL), learning the core commands—CREATE, SELECT, INSERT, UPDATE, and DELETE—through the powerful psql command-line interface. To round out your skills, you'll explore pgAdmin, a popular graphical tool that provides an intuitive, visual way to interact with your database, view tables, and run queries. By the end of this tutorial, you will have the confidence and foundational knowledge required to build data-driven applications and prepare for integrating a database into your FastAPI projects. This guide is your first step towards becoming a full-stack developer.
