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. Joel Kallman – Director of Software Development (Apex)
