Domain Driven Design (DDD) is an influential book by Eric Evans from 2004 - sometimes also referred to as “the big blue book”. This blog post summarizes some of my own understanding of the book and gives you an introduction to domain driven design. Important definitions Domain The domain is the area in the real world which we are writing a computer program about. Model The model is our representation of our domain.

This is a quick review of some important parts of the book “Clean Code: A Handbook of Agile Software Craftsmanship” by Robert C. Martin. Advantages of clean code Better use of your time: Code is read a lot, you forget things, so clean code helps you quickly grasp what the code did. Easier onboarding: Getting co-workers up to speed is much easier if the code base is clean. Easier debugging: Others can help you out, since the code is understandable, even non-programmers like a project manager might be able to spot things.
