We will be using JupyterHub based environment to master Postgresql. Let us go through the steps involved to get started using JupyterHub environment.

  • We will use Python Kernel with sql magic command and for that we need to first load the sql extension.

  • Create environment variable DATABASE_URL using SQL Alchemy format.

  • Write a simple query to get data from information schema table to validate database connectivity.

  • Here is the information you can leverage to connect to the database.

    • User Name: YOUR_OS_USER_sms_user

    • Database Name: YOUR_OS_USER_sms_db

    • Password: Your lab password provided by us
