Free Kit introduces tables, data types, and a first SELECT statement. Axis Set continues with basic query writing. Read the audience section on each course page before choosing.
Do I need previous database experience?＋
Free Kit and Axis Set are intended for beginners. Other courses assume familiarity with tables and simple SELECT queries.

Digital delivery will be described at checkout once ordering is enabled. This site is not currently accepting orders; payment and delivery setup are still pending.
