Oracle APEX is a full-stack low-code platform. The frontend UI (pages, components, charts) is automatically generated using APEX’s built-in page engine, while backend logic is handled using SQL and PL/SQL inside the database.

This means:

• Frontend: APEX page builder, themes, components, forms, charts

• Backend: PL/SQL processes, validations, triggers, APIs

APEX eliminates the need for Node.js, PHP, Java, or .NET because everything runs inside Oracle. It is one of the few platforms where the UI and backend are tightly integrated without external servers.
