Art of Domain Modeling

" summary

Argues that domain quality is the leading indicator for maintainability and feature speed and gives a concrete workflow: iterate early while it's cheap. Uses a pizza-shop example with precise invariants (toppings always add cost; add then remove is a no-op), Clojure-style function signatures, a runnable specification implemented in-memory, and property-based tests. Adds abstract non-domain concerns like immutability, event sourcing, concurrency, then maps to real implementation choices (enums, multimethods, database) guided by volatility analysis.
