  Microsoft Azure Data Fundamentals: Explore non-relational data in Azure 1. Explore non-relational data offerings in Azure 2. Explore provisioning and deploying non-relational data services in Azure 3. Manage non-relational data stores in Azure Explore non-relational data offerings in Azure---------- Introduction Completed 100 XP 1 minute Data comes in all shapes and sizes, and can be used for a large number of purposes.
