Yeah, tables/rows are basically vertices with 1 label & many properties*, and FKs are labeled edges without properties. But, you can easily implement edge prop

Yeah, tables/rows are basically vertices with 1 label & many properties*, and FKs are labeled edges without properties. But, you can easily implement edge properties with many-to-many tables, at the cost of an extra JOIN. In practice, this is a useful and efficient species of graph. I think many people get baited by Neo4j's marketing without really understanding relational models and RDBMS (I sure did). * With the (often true) assumption that many vertices will follow the same normalized schema.
