In this article, we take a look at processing graph-oriented data using Azure Cosmos DB. A graph allows us to represent connections between entities in a convenient and natural way. In many data processing scenarios, we want to efficiently store and analyze huge amounts of these connections.

For example, think about social networks like Twitter or Facebook: They basically consist of a vast number of people that are connected to each other in various ways. By analyzing the connections between them, we can infer social relationships, optimize content delivery and make meaningful content suggestions to users.
