Note: ArcSDE no longer exists since ArcGIS 10.3, instead direct connections will be used.

Note: Further information regarding the installation and configuration of ArcSDE you can find here.

 

Whenever you want to use the WebOffice 10.5 SP2 editing functionality, editable data has to be maintained with ArcSDE or direct connections.
