Why study this course

A crucial skill for anyone working with data is the ability to access and analyse that data. Structured Query Language (SQL) enables users to access data from databases, combine data from multiple related tables, and to aggregate, sort, filter or limit the data retrieved as needed.

You will be guided through the basics of relational databases as well as how to run queries from the Azure portal and from Azure Data Studio.

Learn how to work with data stored in the cloud, develop an understanding of relational databases, and SQL. This course will suit those working towards an Azure Data Fundamentals Certification.
