Logical Rolename |
ColumnName | evid
RoleName |
Definition | Event identifier. Each event is assigned a unique integer which identifies it in a database. It is possible for several records in the Origin relation to have the same evid. This indicates there are several opinions about the location of the event. The evid does not have to be identical to the local network’s event identifier, which is stored in the Origin table. This allows merging data for a single event from multiple sources without insisting that database evid is identical to the source’s local event identifier
