The IoTResource uses a local database (sqlLite) to store Changes in statevariables, events, logs and errormessages. It is possible to configure which statevariables/properties should be logged into the local database. This is done by changing the property logvariables by using the GetProperty and SetProperty actions in the IoTService of IoTResource.

By default  the local database is created in the same directory as the IoTResource executable, but this could be changed in the appconfig-file.
