The Property Graph model of graph databases
The NOSQL category of graph databases, as we have seen previously, is in a class of its own. In many ways, this is because the underlying data model of graph databases—the Property Graph data model—is of a very specific nature, which we will explain a bit further.
First of all, let's define the Property Graph data model. Essentially, it means that we will be storing our data in the graph database.
A graph structure means that we will be using vertices and edges (or nodes and relationships, as we prefer to call these elements) to store data in a persistent manner. As a consequence, the graph structure enables us to:
- Represent data in a much more natural way, without some of the distortions of the relational ...
