What will I learn in the Relational Databases track?

The Relational Databases track covers What a relational database is, Spreadsheets vs databases, Tables, keys, and relationships, Data modeling basics, PostgreSQL and Supabase, and row-level security and multi-tenancy, all in plain language aimed at business owners and operators rather than software engineers.

Do I need a technical background for the Relational Databases track?

No. Every guide is written for non-specialists. Where a technical term is unavoidable, it links to a plain-language definition in the glossary.
