Hi, I want to restrict number of edges between two vertexes to one.
I have a scenario where I have a User vertex and Article vertex. When a user rate an article, we are making an edge from user to article. Now, I don't want users to rate article more than once. How can I make sure there is exactly one edge between two vertexes. I am using orientdb SQL queries. Is their a way I can achieve my goal with SQL?
