ECA: Event-Condition-Action
A state machine model of business
Event: something that happens
Condition: some logical condition (that is a function of state). 
Action: some modification of state as a result. 
In Force, ECA applies to individual objects, and "wraps" objects in a state machine. 
Which implies that objects get big, and are hard to break into pieces.
