AWS CLI Commands

There were two small changes made to the source code, as compared to the video demonstration, to help clarify the flow of data in the demonstration. The prefix for the (7) data source AWS Glue Data Catalog table’s prefix was switched from raw_ from source_. Also, the (7) Raw/Bronze AWS Glue Data Catalog table’s prefix was switched from converted_ to raw_. The final data flow is 1) source_, 2) raw_, 3) refined_, and 4) agg_ (aggregated).
