The Layers of a Stack: The Front End, The Back End, The Database, How the Layers Work Together.

Updated: November 3, 2026

1. [The Front End](https://www.ask-codey.com/lessons/full-stack-the-front-end) (Novice): The front end is the part of an app people see and touch, built with HTML, CSS and JavaScript and, in this course, Angular, and a front-end developer makes it clear, fast and enjoyable on every screen.
2. [The Back End](https://www.ask-codey.com/lessons/full-stack-the-back-end) (Novice): The back end is the code that runs on a server, keeping the rules of the business and answering the front end through an API, and in this course you'll write it in C# with ASP.NET Core.
3. [The Database](https://www.ask-codey.com/lessons/full-stack-the-database) (Novice): The database is where an app keeps its data so it can be found again in an instant, and in this course you'll design SQL Server databases and question them in T-SQL.
4. [How the Layers Work Together](https://www.ask-codey.com/lessons/full-stack-how-the-layers-work-together) (Novice): Follow one pizza order from a tap on the screen, through the API and the database and back again, to see how the front end, the back end and the database work as one app.
