Do any of you use graph databases. If so what? I am not able to understand where they really fit in.

Graph databases are for storing ontological information. Ontologies are specifications that attempt through the use of logical axioms to describe data and the real world in terms that a computer can understand and draw logical inferences/conclusions from.

Graph databases dont store a "row" of data rather they store a triple which asserts a a thing about a thing.

Example: bob is_friends_with alice
Bob is defined, Alice is defined and is_friends_with is defined. In the ontology specification

@Vaccuss That's nice. Thanks bro! Actually, I understand that, I wanted to know the practical applications of it. For eg, what are you using it store?

I see devRant uses it too. @dfox , can you help me understand why you are using neo4j over traditional DBs? Thank you!

Yeah I d like to know too

@vish I'm guessing they use it to represent the social network in a graph. Like how @Vaccuss mentions. Facebook uses it too.

So if you have different objects and their relationships in a graph, it becomes much more efficient to query complex stuff. Like given 2 person A and B, get all the posts of A which are liked by mutual friends of A and B.

I'm no graph db expert‌, this is from what I understand.

Simply explained: you want an object A and some other objects associated with it. Instead of having to JOIN on big tables to get those associated objects, you have them immediately because there is a link between A and each of those objects
