How important is a graph data structure when implementing a KG ?
I do get that graph representation is important for humans to represent knowledge in an easy-to-understand (and communicate) manner. But what do I gain by implementing/storing my KG in a graph (native) database?
If I store my KG in an RDBMS, do I still have a KG, according to you?
In the term "Knowledge Graph", there is "Graph".
