Practical Software Architecture Solutions from the Legendary Robert C. Martin (“Uncle Bob”) By applying universal rules of software architecture, you can dramatically improve developer productivity throughout the life of any software system. Now, building upon the success of his best-selling books Clean Code and The Clean Coder, legendary software craftsman Robert C. Martin (“Uncle Bob”) reveals those rules and helps you apply them. Martin’s Clean Architecture doesn’t merely present options. Drawing on over a half-century of experience in software environments of every imaginable type, Martin tells you what choices to make and why they are critical to your success. As you’ve come to expect from Uncle Bob, this book is packed with direct, no-nonsense solutions for the real challenges you’ll face–the ones that will make or break your projects.Learn what software architects need to achieve–and core disciplines and practices for achieving itMaster essential software design principles for addressing function, component separation, and data managementSee how programming paradigms impose discipline by restricting what developers can doUnderstand what’s critically important and what’s merely a “detail”Implement optimal, high-level structures for web, database, thick-client, console, and embedded applicationsDefine appropriate boundaries and layers, and organize components and servicesSee why designs and architectures go wrong, and how to prevent (or fix) these failuresClean Architecture is essential reading for every current or aspiring software architect, systems analyst, system designer, and software manager–and for every programmer who must execute someone else’s designs.

Robert C. Martin (“Uncle Bob”) has been a programmer since 1970. He is founder of Uncle Bob Consulting, LLC, and cofounder with his son Micah Martin of The Clean Coders LLC. Martin has published dozens of articles in various trade journals and is a regular speaker at international conferences and trade shows. He has authored and edited many books, including: Designing Object Oriented C++ Applications Using the Booch Method, Patterns Languages of Program Design 3, More C++ Gems, Extreme Programming in Practice, Agile Software Development: Principles, Patterns, and Practices, UML for Java Programmers, Clean Code, and The Clean Coder. A leader in the industry of software development, Martin served for three years as editor-in-chief of the C++ Report, and he served as the first chairman of the Agile Alliance. <div id="
I liked this book less than the Clean Code, but it was a better read for me than the Clean Coder. I’ve found a distillation of this book in article from Robert Martin, which he wrote in 2012 while working at 8th Light (I cannot paste a link in here). The book is partially a very detailed description of the ideas from the article and what is behind them.The book starts with 3 myths we developers live in:1. Myth: We just need to get to market first and we clean it up later.2. Myth: Messy code makes us faster today and slows us later. Myth: We can switch mode from making messes to cleaning messes. (making messes is always slower, even in very short term as shown in example of a simple kata in the book)3. Myth: Starting from scratch is a solution.There is a well written history lesson in the next part. Uncle Bob presents Structured Programming, OOP and Functional Programming and says there is nothing else (programming paradigm-wise) to be invented. Part 3 is about SOLID principles from architecture point of view and part 4 are his Component Principles about component cohesion and coupling from his Agile Software Development book.Part 5 is about Architecture and was the most interesting to read. Most memorable chapters for me were the Screaming Architecture and the Clean Architecture. Both of them are not new, you could have seen them in his videos or the article from 8thlight. The point of Screaming Architecture is that when a new developer joins a health-care project, he should be able to immediately tell “this is a health-care project” just from the project structure. Another topic which was part of multiple chapters, are micro-services. I felt that Robert Martin is not very fond of starting with them. He says services are little more than expensive function calls and as a communication mechanism between the project boundaries (i.e. a detail), they are a decision which should be deffered as far as possible.Part 6, the Details, are a detailed explanations of his article Clean Architecture from 2012. There is a little gem in there, the Missing Chapter 34 written by Simon Brown. I liked his explanation of 4 different kinds of packaging classes together to form components.
I was hesitant to buy this book because Uncle Bob is known in software community as a fundamentalist zealot for his views on software design and testing (TDD). This book starts out with similar hard views and he claims that a useless program that is easy to maintain is better than a useful program that is impossible to maintain. I have seen a lot of bad design and implementations in my twenty plus years of experience as a software architect/engineer but nothing is impossible. As a profession software engineer, you are expected to support business and have to work with various constraints in your organization. These constraints vary based on the context and unique environment, which is why I prefer Kent Beck’s advice of making it work, making it right (refactoring) and making it fast.Most of first one third of the book provides overview of programming paradigms such as structured design, object oriented, and functional decomposition. He then covers SOLID principles that he is best known for, i.e. single responsibility principle (SRP), open-close principle, liskov substitution principle, interface separation principle (ISP) and dependency inversion principle. In my opinion, these principles can be boiled down to interface/implementation separation and using composition over inheritance (concrete). He then applies these principles to components design such as reuse/release equivalence principle for releasing same component together, common closure principle similar to SRP and common reuse principle for using interfaces similar to ISP. Uncle Bob provides useful advice for using acyclic dependency principle for dependencies between components and ensuring that abstract/interfaces are used in stable components and volatile components (concrete implementation) should depend on stable components and not otherwise.The last one quarter of the book finally starts with explanation on clean architecture that uses hexagonal architecture. He states that architecture should be independent of frameworks, UI and database. His definition of architecture only focuses on component design and communication but I use architecture as any design decision that is costly to change and often that include choice of databases, frameworks and UI. He uses layers and boundaries to divide system into various components and recommends use of entities for business policies, using techniques such as humble object pattern for testing hard to test components. In final chapters, he proposed designing components based on use cases instead of horizontal, which has worked better in my experience when working on a large system.In the end, this book has plenty of nuggets on design of components but take this advice with a grain of salt. Uncle Bob’s militant views on clean design, test driven development and his abhorrence for tools is not very pragmatic. For example, he doesn’t mention technical debt, refactoring or dealing with legacy systems. Though, he pays attention to maintainability but he ignores most of other non functional requirements such as scalability, availability, reliability and ignores emphasis on developer productivity. In my experience, software design and development should start with the business requirements, constraints and organization structure. You may be working in a startup that needs to prove an idea with minimal effort or you may be working on designing a service with a large number of users. Similarly, you may be working with a small team or on a large project that needs to interact with a number of teams where you may need to apply Conway’s law to design the system. In real world, you face these choices instead of writing perfect components with 100% test coverage, which may be maintainable but not useful to anyone and thus killing your company and leaving you without work.
I’m very disappointed with this book. I had very high expectations of it after having read Uncle Bob’s excellent “Clean Code” and “The Clean Coder”, but after reading this, I can only feel that my money’s only purpose was to help the author set up a second gold-coated swimming pool at their mansion – there was little to learn here.I would divide the book in two halves. The first of these hardly bears any relevance at all – it’s mostly anecdotes and stuff that (in my opinion) doesn’t really need to be in a book about architecture, particularly so if you already have any knowledge of design patterns. (Seriously, why bother explaining structured, object-oriented and functional programming?) The second half is where you’d expect the meaty content to be, but at the end of the day most of it can’t be summarized in a simple sentence: don’t do coupling. Don’t do coupling in your database, don’t do coupling in your services, don’t do coupling in your web frontend… and a chapter for every single place where you want to avoid coupling.To be fair, there is a couple of gems and useful pieces of information scattered across the book, but even in these cases, many of them were underexplained. Too much attention is paid to unimportant topics and too little to the points I found the most relevant.It is rather sad that the only chapter that I found useful from start to end is called “The Missing Chapter”. Perhaps the name is indicative of the fact of how difficult it is to fit a single useful chapter into a otherwise mostly pointless book.
Clean Architecture is basically one idea repeated over and over for 30 chapters. The idea is that the business logic should be self-contained. It should not depend on the database or sockets or frameworks or GUI. It is a really, really good idea, and it is not easy to actually follow. However, the idea could have been explained in a lot less than 300 pages.At the end there is a 50-pages appendix where Robert Martin describes many of the projects he worked on, from the early 1970s to the 1990s. Many of the problems from those projects are interesting case studies that you can learn from – I quite enjoyed reading those stories (somewhat to my own surprise).
If you use the time watching the kardashians instead of reading this book, you will be as good as a software architect as you would be after reading this book because this book is totally useless.This book is nothing than an over verbose description of the SOLID principles.You have to admire the author though. Converting a 2 pages document into a 300+ book require skills rarely seen outside politics
The first five charts in this book (1.1 .. 1.4).1.1: x-axis not defined, y-axis no measure,1.2 x-axis not defined, title is Productivity over the same period of time. What do you mean ‘same period’? The previous chart had no title of x-axis that mentioned ‘time’.1.3 x-axis is named ‘Major release’, the title is Cost per line of code over time (is it ‘Major release’ or is it ‘time’?), Y-axis: no unit.1.4 x-axis: no mentioning. Y-axis not defined.How sloppy can you be? Is there no editor involved?
Zugegebenermaßen bin ich doch etwas enttäuscht. Von Uncle Bob hätte ich mir da deutlich mehr erwartet.Die ersten Kapitel waren wirklich sehr dünn, als Quereinsteiger eventuell hilfreich aber zum Großteil allgemein bekannte Dinge.Ab dem Kapitel “Clean Architecture” geht es dann wirklich los. Es wird viel über Boundaries gesprochen und häufig wiederholt, dass man Designentscheidungen möglichst vermeidet und alle Optionen offen lässt. Das ist ein guter Rat, hat aber mit Software Architektur nicht besonders viel zu tun, denn diese Endscheidungen zu treffen ist ja genau der Punkt. Es bleibt auch alles wenig konkret. Die Kernaussage ist, dass man sich seine Businesslogik frei von Abhängigkeiten halten soll und das wird auch mit trivialen Beispielen gezeigt. Leider ist die Welt nicht so trivial und auch die Case Study gibt keine konkreten Tipps.Ja die Dinge, die angesprochen werden, kann man so unterschreiben, aber der große Erkenntnisgewinn bleibt aus. Letztlich keine Kaufempfehlung, da gibt es bessere Bücher. Beispielsweise Game Engine Architecture, was zwar auf die Spieleentwicklung abzielt aber auch für andere Bereiche interessant ist. Hier geht es es ins Detail und die konkrete Umsetzung.
This book introduces a set of important principles for building software right like SOLID.I quite enjoyed reading it, which is rare with technical books.I think it is very good for someone that has some idea of clean code, design patterns and software architecture principles already and wants to understand where these ideas come from and how they fit together.
