Замечания
In SQL Server 2005 Notification Services, you can specify the name of the application database. This database can be a new or existing database. If the database already exists, Notification Services creates application database objects in the specified schema of the existing database. If the database does not exist, Notification Services creates a new database with the specified name and creates application database objects in the specified schema.

|---|
| The specified database must be using 90 compatibility mode. |
If you use the DatabaseName element, you should specify a unique schema name using the SchemaName element.
If you do not use the DatabaseName and SchemaName elements, Notification Services creates a new database with the name instanceName + applicationName, and creates all application database objects in the dbo schema. The instanceName and applicationName values are defined in the ICF.
When you delete an instance of Notification Services, Notification Services will delete the application database only if Notification Services created the database. Otherwise, Notification Services only deletes application objects from the database.
For more information about database names, see the database_name parameter in CREATE DATABASE (Transact-SQL).
Пример
The following example shows how to use the Stock database as the application database. If the Stock database exists, Notification Services uses the existing database. If the Stock database does not exist, Notification Services creates it.
<DatabaseName>Stock</DatabaseName>
