SQL From Scratch – Chapter 1 | Databases vs Files, DBMS, Relational Model & How SQL Really Works

In this live SQL session, we begin with Chapter 1 of the Complete SQL Learning Roadmap. Most people jump straight into SELECT queries and then struggle later because they never understood what SQL actually is or how databases think. This session fixes that foundation. What you’ll learn in this live class: Why file systems fail and why databases exist What a DBMS really does behind the scenes What makes a database relational How tables, rows, and relationships actually work What SQL is (and what it is NOT) Why SQL is a declarative language How SQL queries are processed internally Common beginner misconceptions that cause long-term confusion This is not syntax memorization. This is about building the correct mental model so future SQL concepts make sense instead of feeling random. Who this session is for: Absolute beginners in SQL Students preparing for placements or interviews Developers who “use SQL” but never understood it deeply Anyone who wants a structured, chapter-wise SQL course What’s next: In the next chapter, we’ll move into database structure, schemas, tables, and data types, where design mistakes start becoming permanent. 📌 This is Chapter 1 of a complete SQL series.
