Think of SQL (Structured Query Language) as asking questions to a database (how many, what is the, etc.)

This article will be a brain dump on how to use the PostgreSQL relational database management system (RDBMS).

The focus will be on key and advanced concepts about the SQL standard language and how it is used in PostgreSQL.

We will use PgAdmin as a dashboard to make SQL queries. It is exactly the same queries that you will be executed in your Node.js applications (with the help of an object relational mapping [ORM}module like TypeORM for TypeScript afficionados).
