daily_grind.sql
  The file Chapter 2 tells you to download: CREATE TABLE statements for
  all five tables, then the INSERTs that fill them - 15 products, 12
  loyalty customers, and a summer's worth of orders. Run it once in any
  SQL tool (DB Browser for SQLite: File > Import; playgrounds: paste and
  run; MySQL Workbench / pgAdmin / psql: open and execute) and you have
  the exact database queried throughout the book. Printed in full in
  Appendix F.

daily_grind.db
  The same database, already built, as a ready-to-open SQLite file: in
  DB Browser for SQLite choose Open Database and skip the import step.
