Hi, I'm just starting out investigating graph databases and OrientDB and
I'm trying to work out how to best model this scenario:
In my app a user can tag a resource but I also need to know who tagged
which resource. In a relational database I would simply have a join table
which can be used to discover which user applied a particular tag. In my
initial attempt at converting this to a graph model I had 3 vertices for
Person, Resource and Tag but couldn't work out how to define edges that
allow me to determine which person applied a tag.
All I could come up with is to add a fourth vertex to represent the actual
tagging event ('Review' in the schema below).
Is this how you experts would handle such a scenario or is there a better
way?
