About This Course

In this course, you will build a full-stack ride-sharing application in Python using the popular SQLAlchemy ORM. You will start with a simple version that manages a fleet of scooters and their current positions. You will add features one by one as the course progresses until you have a highly functional application that is ready to track multiple vehicle types and users at scale.

In this course, you'll learn how to:

  • Create and modify a table in the SQL shell
  • Model your data's schema in SQLAlchemy
  • Perform transactions using SQLAlchemy

For this course, you’ll be using CockroachDB Serverless, which is our database-as-a-service offering.

Prerequisites

Before taking this course, you should have experience with Python and application development.

It is helpful but not required to be familiar with SQL.

If you’ve never used CockroachDB Serverless before, we would also suggest taking our “Introduction to Serverless Databases and CockroachDB Serverless” course first.
