Managing the flow of data through a website or app is a crucial skill to master if you plan on making any sort of modern web service. With flask, Object Relational Mappers (ORM’s) are employed to allow your app to interact with a relational database. An Object Relational Mapper is a framework that, in our case, will allow us to interact with a SQL database using python instead of explicit SQL queries. The name of the ORM we are using is SQLAlchemy and can be downloaded as follows:

pip install flask_sqlalchemy

pip install psycopg2-binary #for using postgres

This article assumes that you have some basic knowledge of SQL, and have Flask, PostgreSQL, and pgAdmin installed on your machine.
