In preparation of a new blog post on Dataversity, I am researching connectedness in SQL databases vs. graph databases. My hypothesis is that connectedness in relational databases is significantly lower than in real-life graph databases. So far the relational survey does indeed show some rather low numbers for connectedness in production SQL databases.
This survey aims to compile some real-life numbers from production graph databases. This is not pretending to be precise science, just trying to get a rough picture to compare with the SQL relationship modeling real-life practises.
Your input is much appreciated. - Thomas Frisendal @VizDataModeler
