If you've taken the first course in this specialization and exploring your data with BigQuery, you're already familiar with the e-commerce course dataset that we've been using so far. If you skip the first course, here's a brief recap of the dataset that we'll be working with. Dataset that you use for your hands-on labs is a year of Google Analytics records behind the Google merchandise store, which sells Google brand and merchandise like sunglasses and even t-shirts. That's over a million site hits and transaction records, to include insights like, what users were close to transacting but never completed? What top keywords are high-value customers using to reach the site? What top channels are customers going through to reach your site? We made a copy of this public dataset in the Did It Insights course. So, take a look at this resource link to look at the field definitions of the dataset, and I often keep it open in a new tab for future reference.
