[Data-modeling] underlying graph database

[Can Altineller]

Hello John,

Is your graph database based on object oriented database logic? In
otherwords, lets say you have a node - and want to get neighbooring nodes:
does your database require a BTree search again, or do you just track
objects without making any search as in an object database?

Best Regards,

-C.A.
