Many-to-Many Relationships

In this module, you will discover why graphs excel at many-to-many relationshipsA named, directed connection between two nodes. Every relationship has a type, a start node and an end node..

By the end of the module, you will:

• Understand how graphs eliminate the need for join tables
• Learn how many-to-many relationships work in graph databases
• See how relationship propertiesA named value stored on a node or a relationship. capture connection context

Optional lessons provide hands-on practice with:

• Creating Category nodesA vertex in a graph. In a property graph it can carry labels and properties. and IN_CATEGORY relationships
• Creating CONTAINS relationships between Order and Product nodes
• Writing multi-hop traversalFollowing relationships from one node to the next to reach other parts of a graph. queries across the entire graph
