Analysis covers the occurrences of objects.
If the occurrence level is analyzed, all occurrences of an object are included. This means that an object is included as many times as the number of occurrences that exist of that object.
This can be illustrated by the example of the evaluation level for query items.
For the query items Object and Connection you can define whether the query will relate to object definitions or object occurrences. Depending on the selected level, the query returns different results.
If occurrence level is selected, the result of the query relates to the object occurrences.
