Summary

Since Evans’ 2003 book, Domain-Driven Design: Tackling Complexity in the Heart of Software, the software community has increasingly adopted the DDD approach. Evans’ emphasis on understanding and modeling the problem space before implementing technical solutions marked a significant shift from traditional methodologies, especially in refactoring.

This chapter highlights the evolution of DDD and its influence on refactoring practices. Key contributions include Nilsson’s practical applications, Greg Young’s CQRS pattern for complex domain logic, and the resurgence of DDD with microservices architecture. Vaughn Vernon’s work gave practical examples, while Alberto Brandolini’s EventStorming improved communication between domain experts and developers.

In conclusion, DDD transforms refactoring by prioritizing domain understanding and communication, leading to more intuitive, business-aligned, and resilient software solutions.

Alberto Acerbis

Alberto Acerbis

Alberto Acerbis is basically an eternal student because the subject matter is endless. He has always defined himself as a backend developer, but he does not disdain poking around on the other side of the code either. He likes to think that 'writing' software is mainly about solving business problems and providing value to the customer, and in this, he finds DDD patterns a great help. I am a co-founder of the DDD Open and Polenta and Deploy communities.
