SQL & Databases for Beginners
Description
Query, join, and design relational databases. One of the few technical skills that has barely changed in decades — and one nearly every technical role eventually requires.
Features
- Two sample tables used consistently — every query is runnable
- Joins explained by what they return, not abstract diagrams
- The NULL and HAVING rules that confuse beginners
- Safe practice for UPDATE and DELETE with transactions
Target Audiences
- Developers who need to work with data confidently
- Analysts writing their own queries instead of requesting them
- Anyone moving into a data, backend, or reporting role
- Business users who want direct access to their own systems
Requirements
- A database to practise on — SQLite, MySQL, or PostgreSQL (all free)
- Or an online SQL playground, no installation needed
- No programming experience required
- Basic computer literacy
