I'm taking the course from Graph academy and following is the question where I'm looking for more clarifications : The question accepts multiple options.
What types of constraints can you define for a graph that are asserted when a node or relationship is created or updated?
- unique values for a property of a node
- unique values for a property of a relationship
- a node must have a certain set of properties with values
- a relationship must have a certain set of properties with values
Based on my exploration sofar I feel that all of these are valid constraints that can be applied on the Graph node or relationship.
When I try to select all of these options or first two or last two options the system is throwing back as incorrect answer.
Any help in this regard in much appreciated.
