# <a id="appendix"></a> Appendix
## <a id="schemas"></a> 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_
### <a id="schema-status-files"></a> 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)
### <a id="schema-db-ido"></a> 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]
#### <a id="schema-db-ido-extensions"></a> DB IDO Schema Extensions
Icinga 2 specific extensions are shown below:
New tables: `endpoints`, `endpointstatus`
