Analysis covers the definitions of objects.
If the definition level is analyzed, the objects themselves are included. This means that an object is included only once, regardless of how many occurrences of it exist.
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 definition level is selected, the result of the query relates to the object definitions.
