Today, we are going to be going over a very useful tool called Sequelize. It is an Object Relational Mapper (ORM), which allows us to interact with relational databases using Node.js.

Several migrations between MongoDB add-ons have already happened because of shutdowns. So, it was decided that rather than migrating to the last one still in existence, the project would switch to using PostgreSQL, which is supported directly by the Heroku team.
