Snowflake: Hands-on with the Snowflake Data Marketplace, Wunderman and COVID-19

Posted by

The Snowflake Data Marketplace is quickly becoming one of my favourite things about working at Snowflake. With the marketplace I have live, instant access to some of the worlds best datasets to give my data deeper context and meaning. I had the pleasure of recently presenting a virtual hands-on lab (recording) with Snowflake using Starschema’s COVID-19 dataset (link) and Wunderman Thompson’s COVID-19 Risk, Readiness and Recovery dataset (link) built on the backbone of their fabulous Amerilink Insights dataset. I highly recommend both datasets to drive a deeper understanding of our collective pandemic context. The best part is they are both free to play with, free! I love me some free data…let’s geek out!

Getting and querying data from the Snowflake Data Marketplace is dead simple and built on a very powerful premise. After 3 clicks of the mouse, I have data that is ready for analysis and always in sync with Starschema’s or Wundermand’s latest updates. This means I have instant access to a single-source of truth on COVID-19 cases as reported by public health authorities around the world along with key economic drivers to enhance my data.

Getting Started
First, you will need a Snowflake account if you want to run these queries. Snowflake offers free trials (link) to get started, even with these powerful datasets. If you have an existing account you must be the ACCOUNTADMIN to follow along. Grab a full copy of the SQL file (here).

Login to your Snowflake account and switch your context to ACCOUNTADMIN.

Browse to the Data Marketplace.

Get the Starschema COVID-19 set by browsing to the Health category or searching.

Get the data and assign to roles that need access, keep the name as “STARSCHEMA_COVID19” or the later queries will not work.

Starschema COVID-19 Data Set Queries
Now we are ready to start querying the data, please go ahead and create a new worksheet and paste this code for your own use. Be sure to set the session variables to a meaningful context or these queries will not run. Grab a full copy of the SQL file (here).

Conclusion
As you can see for yourself the Snowflake Data Marketplace is an amazing place where data enthusiasts are coming together to further enhance data as actionable and meaningful to your narrative. With just clicks of a mouse, we were able to query 4 different data sources with COVID-19 cases, weather, population and demographic insights across the globe. I highly encourage playing around in the marketplace. Happy (Data Marketplace) Querying!
