Question

Answer 1

Notification Services contains four components as follows:

Subscription:

Subscription data can be added by using Subscription Management Objects (SMO) to Notification Services application.

Events:

Events find as populated to events table along with the help of Event providers.

Generator:

While events are populated in events table, the generator wakes up and begins processing rules which are attached along with subscriptions. The generator verifies to see when any events match them. The generator begins creating notifications and fills the Notifications table, when matches are determined.

Delivery of notifications:

While notifications arrive within Notifications table, the distributor wakes up and begins processing each notification, formats this and delivers them by using given channel.
