# Appendix
-
-## Schemas
-
-By convention `CheckCommand`, `EventCommand` and `NotificationCommand` objects
-are exported using a prefix. This is mandatory for unique objects in the
-command tables.
-
-Object | Prefix
-------------------------|------------------------
-CheckCommand | check_
-EventCommand | event_
-NotificationCommand | notification_
-
-### Status Files
-
-Status files used by Icinga 1.x Classic UI: `status.dat`, `objects.cache`.
-
-Icinga 2 specific extensions:
-
-* host and service objects support 'check_source' (added in Classic UI 1.10.0)
-* command objects support custom variables (added in Classic UI 1.11.2)
-* host and service objects support 'is_reachable' (added in Classic UI 1.11.3)
-
-### DB IDO
-
-There is a detailed documentation for the Icinga IDOUtils 1.x
-database schema available on [http://docs.icinga.org/latest/en/db_model.html]
-
