This month, Hari Krishnan ( will be presenting a trigger architecture that builds on the design patterns published by Dan Appleman in Advanced Apex Programming ( and Tony Scott (

Also, Holly Goldin ( has invited us all to a Meetup Afterparty Mashup! Drinks and prizes provided by Atlassian. Details below!


The Apex Trigger Architecture Framework is built on the design patterns published by Dan Appleman and Tony Scott. It provides a comprehensive way to handle Apex trigger events on the platform and satisfies the following four concerns:

• Order of execution

• Separation of concerns

• Control over reentrant code

• Providing a structured and organized codebase

In this session, we will explore the core pillars of this framework - the dispatchers, the event handlers, the trigger factory - and will go through a simple demo to understand how it works.
