Getting started with Neo4j Step 2/11 What is a graph? Concepts A graph database stores nodes (Supplier, Product, etc) and their relationships (e.g. Supplier SUPPLIES Product). Other types of databases may use tables and documents, but in a graph, data is stored in the same way as you may sketch ideas on a whiteboard. In relational databases, you are often required to add explicit joins to your queries. In doing this, relationships are calculated at runtime, which can be an expensive and slow operation. In a graph, where the relationships are stored, many powerful operations are faster and simpler. Schema-free In a relational database, you must define your schema (the structure of the data). In a graph, your data is managed without restricting it to a predefined schema. This allows more flexibility in thinking about the data and in evolving it.
