The "zooming" feature warrants its own vignette. Let's start with a script and one-line comments that describe what's happening here.

  • based on nycflights13
  • zoom, add a new column to one of the tables, update
  • bring in data from a related table, as in Mutating from different tables #92
  • create two tables for airports: origin and destination
  • compute a summary of the flights table that keeps links to one or two dimension tables (zurich2)
  • create surrogate key (zurich2)
  • possible pitfalls, which operations are supported?
  • caveat: loss of key property when mutating
