Udemy – MIT App Inventor: The Complete Database Masterclass

Master every major database and cloud storage technique in MIT App Inventor — from local offline persistence to real-time synchronized cloud databases and relational MySQL backends.

Whether you are building your first data-driven mobile app or looking to create scalable multi-user applications with secure authentication, this hands-on, project-based masterclass gives you the complete blueprint.What You Will Learn & Build:

• Local Storage with TinyDB: Store user preferences, game scores, and offline application state that persists across app restarts.
• CloudDB & Real-Time Sync: Synchronize data across multiple devices in real-time, enforce unique username verification, and build a fully functional live multi-user chat app.
• Google Sheets as a Database: Learn two distinct industry methods — using the official Spreadsheet component and leveraging the Web Component with Google Apps Script for live querying, automated lead capture, and relational data filtering.
• Firebase Realtime Database: Link your project to Google Cloud, handle live data change listeners, upload and display images with Firebase Storage, and create a dynamic cloud content app.
• Modern User Authentication: Implement professional user registration and login workflows with credential validation and secure password verification logic.
• Relational Databases with MySQL & PHP: Connect mobile apps to relational MySQL databases via custom PHP REST endpoints, executing complete Create, Read, Update, and Delete (CRUD) operations.
• Comprehensive Capstone Project: Build an end-to-end real-time mobile voting application with live synchronizing UI and multi-user data models.
