In graph databases, a graph can be used to represent data entities, their attributes, and relationships. The vertices of a graph database are called nodes and edges are called edges.A graph database is a set of nodes, edges, and properties. Nodes in a graph database represents entities. ...
In a knowledge graph, nodes can be resources with unique identifiers, or they can be values with literal strings, integers, or whatever. The edges (also called predicates or properties) are the directed links between nodes. The “from node” of an edge is called the subject. The “to node...
Graph neural networks apply the predictive power of deep learning to rich data structures that depict objects and their relationships as points connected by lines in a graph. In GNNs, data points are called nodes, which are linked by lines — called edges — with elements expressed mathematically...

As seen in the above example, the PGQL code is simpler and much more efficient. Because graphs emphasize relationships between data, they are ideal for several different types of analyses. In particular, graph databases excel at: Finding the shortest path between two nodes ...

Below is a detailed overview of how graph databases work: Data Model: Nodes: Nodes represent entities or data points in the database. Each node can have one or more properties, which are key-value pairs containing information about the node. Edges (Relationships): Edges represent the connection...
Nodesare entities in the graph which can: Be tagged withlabelsrepresenting their different roles in a domain (e.g.,Person). Hold any number ofkey-value pairsas properties (e.g.,name). Beindexedand bound byconstraints. Relationshipsprovide named connections between two nodes (e.g.,Person-LOVE...
1. Not to be confused with a chart, a graph (/graf/) represents of connected values in a multidimensional space. Graphs are useful for analyzing the various connections between individual units of data.2. In mathematics, graphs are an important computational tool. Graph values are called nodes...
