Building Instagram.com Database Model

Create the database model for Instagram

Important: To do this activity you need to fork this repo into your Github account and then open the forked repo on Gitpod.

Inside he src/models.py file you will find a couple of classes describing an example database.

Here is a 4min video explaining what UML is: https://www.youtube.com/watch?v=UI6lqHOVHic

The diagram.png file generates a database chart based on the classes that you will be creating. Such charts in Database Management are referred to as ERDs (Entity Relatonship Diagrams).

Please watch these two short videos explaining ERDs: https://www.youtube.com/watch?v=QpdhBUYk7Kk&t=4s https://www.youtube.com/watch?v=-CuY5ADwn24&t=738s

You will have to create the Entity Relationship Diagram for Instagram's Database - a very similar diagram to this one:

💻 Installation

1. Get inside the environment $ pipenv shell

2. Install all dependencies $ pipenv install

3. Generate the diagram as many times as you need $ python3 src/models.py

4. Open the file diagram.png to check out your ERD diagram!

📝Instructions

Your job is to update the src/models.py file with the code needed to replicate Instagram's data model.

The project is using the SQLAlchemy Python library to generate the database.

• What tables do you think Instagram might have on its database: E.g: Post, User, etc.?
• What properties should go inside the user? or inside the Post table?
• Please add at least 4 models with all of its properties.
• Refresh the diagram.png file at the end by running $ python3 src/models.py on the console.
