About This Course

Databases store and manage virtually every piece of data in the modern world — your bank balance, your social media posts, your medical records, your e-commerce orders. Understanding how they work is not optional for any serious developer.

This course teaches database theory and practice from first principles. You will design databases with ER diagrams, normalize them to eliminate redundancy, write SQL queries from basics to advanced joins and subqueries, understand transactions and ACID properties, learn how indexes make queries fast, and explore when to use NoSQL databases instead of relational ones.
