The relationships are really important and enable you to create Dashboards, Profile packs and queries.
There are three main types of relations:
1. To include the value from a pick-list.
2. When you add a direct relationship to one or more objects, like adding a Risk to a Benefit, or adding child
Measures to another Measure.
3. When you need extra information to be stored about the relationship between the objects, like relating a
Measure to its Benefit and adding in a sort order.
