Demystifying Design Patterns: A Practical Guide for Developers
summary
Covers UML and SOLID with concrete refactors: split Order/Notification for single responsibility, wrap DB access behind an abstraction for dependency inversion so mocks and tests become easy. Shows creational solution using a Factory pattern to move payment-instantiation out of the client, a concrete Adapter pattern that converts XML to JSON between client and processor, and a Strategy pattern (checkout service selecting handlers) that orchestrates card/crypto processors so new methods add classes not edits.
