What the class covered

This class introduced the basics of backend development and explained the difference between front end and back end of websites. Dr. Daniel showed how backend handles important tasks like storing data, processing payments, and securing websites through authentication and authorization. He demonstrated practical examples using the Tanics app, including managing messages, adding WhatsApp buttons, and controlling user permissions. The class emphasized the importance of backend for website security and functionality.

Key takeaways

• Every website has a front end (what users see) and a back end (what runs behind the scenes).
• Backend tasks often involve creating, reading, updating, and deleting data (CRUD).
• Authentication verifies who you are; authorization controls what you can do on a website.
• Databases store data like images, messages, and user information securely.
• You can add features like WhatsApp buttons to your website easily using Tanics.
• Backend integration is necessary for secure payment processing and managing user inputs.
