The below instruction videos discuss in detail both theory and practice around relation direction and behavior.
We touch upon the following sub topics:
Relation direction principles
Primary nodes and the primary node network
Relation behavior principles
Relation direction and behavior analysis
Advanced modeling really is a skill that one needs to practice to become good at it. You are invited to follow the instruction videos to learn to analyse your own model to improve relation direction and behavior.
