Defining Notification Classes
A notification class defines one type of notification generated by your application. When you define a Notification Services application, you create one notification class for each type of notification that is supported by your application.
When Notification Services creates the application, it uses the information in each notification class definition to create the tables, views, stored procedures, and functions that store and manipulate notification data, to associate content formatters and delivery protocols to format and deliver the notifications, and to specify operational settings for the notification class.
The following list shows the typical steps for defining a notification class:
- Name the notification class and optionally designate the SQL Server filegroup for the database objects associated with the notification class (such as the notification table).
- Define the notification class schema. The schema defines the form of the raw notification data, which is formatted and sent to your subscribers. Notification Services uses this schema to create a table that stores notification data, as well as other database objects.
- Declare the content formatter for the notification class. The content formatter takes the raw notification data and formats it appropriately for presentation to the recipient.
- Optionally select digest or multicast delivery.
- Optionally specify a notification batch size.
- Configure one or more delivery protocols for notification delivery.
- Optionally specify a notification expiration age.
Your application can have multiple notification classes if it supports multiple types of notifications. For example, a stock application can generate notifications about current stock prices and end-of-day portfolio value. Each type of notification has its own notification class with its own schema and settings.
