striving for perfection: the ultimate apex application architecture
DESCRIPTION
APEX supports a flexible architecture. That means that there are multiple ways of solving problems like: separation of data and logic, security issues, re-use, including javascript and CSS, etc. etc. In this session I'll give the pro's and cons of each available option. As this is aimed to be an interactive session, the attendees are encouraged to put forward their own ideas - and concerns. So, maybe, in the end, we'll reach the "Ultimate APEX Application Architecture"!TRANSCRIPT
