Data Vault on BigQuery

 

In this workshop you will not only master BigQuery, but also learn that unlike traditional data modeling techniques, Data Vault model is highly scalable and can adapt easily to ever changing business requirements. During the course we simulate a real-world end-to-end scenario – processing metrics generated by devices that capture usage in real-time. The technology that we will use is BigQuery. All exercises will be done within BigQuery UI on Google Cloud Platform.
