InfoQ’s Jonathan Allen talking to Daniel Kirstenpfad, founder and CTO of sones GmbH, creators of sones GraphDB:
Jonathan Allen: Can you explain what a graph databases is and why developers would choose one over a tradition database?
Daniel Kirstenpfad: […] o unlike other database approaches which only implicitly can form a graph structure a graph database explicitly represents a graph. And while other databases need to use indices and relational helpers (like relational tables which are coupled using JOINs) a graph database can traverse from one object to the next objects because those objects are organized to have index free adjacency.
While experimenting with another graph database, neo4j, I’ve found the lack of implicit direct node referenceability quite awkward.
