US Patent 7774792 Automatic create, update and delete event publishing

A system for providing automatic event publication relative to data owned by a service is disclosed. A service which owns data publishes internal events when data is created, updated, or deleted. These internal events are only visible by consumers on the same physical computer and running within the same process or executable. Consumers who are located remotely or in a separate process cannot subscribe to these events. Embodiments provide the ability to expose local entity create, update, and delete events as “public” events (or out-only messages) on a service contract. This allows external consumers who may be remote and even on a different platform, to subscribe and receive notifications of when data changes in the owning service.
