How to send data when using Oracle Change notification from Data Access layer to Application layer

Hi I am planning to use oracle change notification feature in C# using OracleDependency class. Whenever there is change in the data, we get the notifications from database that there is a change in the data access layer. So we can connect to DB and get the new开发者_如何学Python data, but how can we send this new data back to the application(console app)?

Sounds like OCI Result caching, but not sure how that fits in with C#.

I am passing a delegate function as a parameter to data access and whenver database sends notification, the event is passed to the delegate function.
