# Intro to SQL & Databases This project is a *thorough* introductory course in **[SQL ](https://en.wikipedia.org/wiki/SQL)** and **[databases ](https://en.wikipedia.org/wiki/Database)** based on the free and open-source database **[PostgreSQL ](https://www.postgresql.org/)** (or "Postgres" for short). ## Installation To follow this course, an installation of **PostgreSQL 13** or higher is expected. If you know how to do this on your own machine, you may do so at your own discretion. Yet, to ensure that each student has a development environment similar to the instructor's one, follow this *extensive* **[installation tutorial](INSTALL.md)** and set up a [virtual machine ](https://en.wikipedia.org/wiki/Virtual_machine) with all the required software on it. The estimated time for this should be around *one hour*.
