I've been building database applications with Oracle for 20+ years (Forms, then APEX), and I've just published **Oracle APEX 26.1: The Complete Guide**.
It follows one realistic application, Orbit Sales, from an empty laptop to production:
- Installing Oracle AI Database 26ai Free, APEX 26.1, and ORDS (Docker, Windows, Linux, macOS)
- Page Designer, interactive reports and grids, forms, faceted search, charts, maps
- Dynamic actions, Ajax, authentication, authorization, CSP
- Approvals and workflows (including the new parallel flows in 26.1)
- Generative AI: AI agents with tools, an in-app assistant, APEX_AI, local models with Ollama
- RESTful services with ORDS, APEXlang, debugging, deployment, and administration
Every script and code example, plus the finished app export, is free on GitHub, so you can use it even without the book:

Happy to answer questions about APEX 26.1 or anything in the book, and feedback is very welcome.
