Characteristic	Description
Data type	string, between 0 and 128 characters in length.
Default value	The /Database/DefaultFileGroup value (if specified) or the application database's primary filegroup.
Occurrence	Optional once per EventClass element.
Updates	Can be added, deleted, and modified when updating the application.

Relationship	Elements

重要提示：
If you update a FileGroup element, updating the application deletes and re-creates the event class to which it corresponds. This includes dropping and re-creating the SQL Server tables and indexes used by this event class. Any data existing in the original SQL Server tables is permanently deleted.

The following example shows how to have Notification Services place the event class tables in the Events filegroup.

<FileGroup>Events</FileGroup>
