SQL and Databases for Beginners - Deploy to AWS

You use databases every time you tap your phone. You just don't know it yet. In one hour, you'll go from zero to deploying your own database to the cloud. We'll start from absolute zero — what a database is, CRUD operations, tables, primary keys — then build everything hands-on in MySQL Workbench: constraints, normalization, foreign keys, one-to-one, one-to-many, and many-to-many relationships with real SQL joins powering features like profiles, feeds, and likes. By the end, we'll take it all to production on Amazon RDS.
