Complete Database Course: SQL, MySQL, PostgreSQL & MongoDB

This course delivers a practical, hands-on tour of modern database systems. Logic Labs structures the content so you move from writing basic SELECT statements in SQL to managing relational schemas in MySQL and PostgreSQL, then pivot to document modeling in MongoDB. The exercises are concrete: you will normalize tables, write joins, and aggregate data, before exploring JSON-like documents and aggregation pipelines. The instructor balances theory with real-world scenarios, making it easier to understand when to use a relational engine versus a NoSQL store. By the final sections, you will have built a functional schema migration workflow and learned how to query across different data models. It is a solid foundation for anyone looking to move beyond spreadsheets into structured data management.
