I know that the Site id is to see where the ticket is originated from and it is defined int he sites table.
But what I am trying to understand is that everytime a table is related to another table let's say NodeID in the Alert table looking up the nodeid in the Nodes table they are also related by InstanceSiteID column and this is the case will every other relationship.
Why are we relating the instacesiteids and what happens if we don't?
