Graph databases are NoSQL databases that are specialized in storing data with complex relationships. Ironically, relational databases are not very good at that. Microsoft added basic support for graph databases in SQL Server and Azure SQL databases a few years ago. Cosmos Db also offers graph support through Gremlin. In this session, we will take a look at how graph databases work and what they can do for your projects. After discussing the basics, it's all demos. We will look at how to create, populate and query Graph databases on both SQL Server and Cosmos Db. Topics such as performance, limitations, and comparison to 'normal relational' databases will be covered.
