Data Refresh

Let's put the browser/OS value back the way it was... we don't want to mess with our original data set. I just wanted to show you how cool it is that an update to the source data cascades through all the transformations when we refresh.

Assignment

Again, open website_sessions.csv in your text editor of choice.
Edit the browser_os field in the first data row (SESSION_0001) back from Firefox|Linux to Edge|MacOS, then save the file.
Refresh the data.

Save the project and, from the course directory, submit the CLI tests.
