Notification Services is a cool new feature in SQL Server 2005 that enables a subscriber to receive notifications using their PDA's, Cellphone, email or through text file when a specific event occurs.
In notification services, we have a file known as Configuration file and the Application Definition file, which is used to configure notification services, which by the way is an XML file. The configuration file contains the settings for an instance of the notification services and the ADF (Application Definition File) contains the setting for individual application in an instance of Notification services.
Next we have events. Events are anything that a user might want to be notified about. For example an updated score of NBA games per quarter. the stock prices, flight schedules, etc. An event provider will submit event to the notification services that will store event information on the database table.
Subscriber are users who receive the notification of a particular event that occurs.The subscription stores the information about the subscriber and the event they wished to be notified of.
Last is the distributor. The distributor formats the appropriately and sends it to the devices specified by the Subscriber.
