EventCache Table

The EventCache table stores the list of site events for which users have requested alerts. Microsoft Windows SharePoint Services inserts records into the EventCache table as they occur.

Warning Modifying the database schema or database structures is unsupported. Changes that you make to the database contents may be overwritten when you install updates or service packs for Windows SharePoint Services, or when you upgrade an installation to the next product version.
