Method and system for non-intrusive event sequencing

A system has a repository that stores a plurality of events. Each event requests to utilize one or more functions in a component. An event sequencing module analyzes an event sequencing key of the event if the event requests a function having a component definition that includes an event sequence qualifier. The event sequencing module grants a lock to the event for the function if no other event having the same value for the event sequencing key has the lock for the function. The event sequencing module prevents the event from being processed if another event having the same value for the event sequencing key has the lock for the function. The event sequencing key is composed of one or more object attributes. The system has a worker server that receives the event, if the event obtains the lock, and processes the function requested by the event.
