Yup. Bakeries have been run using a pen and paper daybook and the master baker’s skill for centuries. But the calculations are still a pain in the arse, so automating that is a big win. The Bread Matters spreadsheet I based the database schema on was made by someone who was a baker, not a programmer, and for a fixed set of recipes, it’s brilliant. If I hadn’t known the rudiments of RDBMS design I’d have bitten the bullet, extended the sheet and grumbled every time I had to add a new formula.
