UNDERSTANDING CLEAN ARCHITECTURE IN SOFTWARE DEVELOPMENT

Origins and Evolution of Clean Architecture The concept of Clean Architecture was formalized by Robert C. Martin ("Uncle Bob") in 2012. It was not a discovery of new principles, but a synthesis of several existing architectural patterns designed to address the increasing entanglement of business logic with framework-specific code. 1. The Precursor Patterns Clean Architecture integrates ideas from four primary architectural movements: Hexagonal Architecture (Ports and Adapters): Developed by Alistair Cockburn around 2005. It introduced the idea that an application should be equally driven by users, programs, automated tests, or batch scripts, and be developed and tested in isolation from its eventual run-time devices and databases.

This pattern placed the Domain Model at the center and established the rule th
