Design Guidelines
• Use the declarative features of APEX as much as possible,
don't write code.
• When you need to venture outside the declarative features of
APEX and you need to write code in PL/SQL, be smart about
it.
• Avoid huge sections of JavaScript and use Dynamic Actions
wherever possible.
• APEX is just a thin veneer over your database - architect your
APEX applications as such.
