Want to start developing web applications with Oracle Application Express? Make sure you don't reinvent the wheel and adapt good practises from industry experts right from the start.
Here are some tips for beginners:
1. If you don't already have APEX installed, don't install it yourself, but get a free workspace within minutes on apex.oracle.com to be used for demo purposes.
For production purposes, you can use the free tier on cloud.oracle.com with two databases up to 20 GB data without any cost.
