WebApr 23, 2024 · A graph, in the context of graph theory, is a structured datatype that has nodes (entities that hold information) and edges (connections between nodes that can also hold information). A graph is a way of structuring data, but can be a datapoint itself. Graphs are a type of Non-Euclidean data, which means they exist in 3D, unlike other datatypes ... WebGraph Databases. Joe Celko, in Joe Celko’s Complete Guide to NoSQL, 2014. Abstract. Graph databases model relationships, not data.
