Readable Code - Why, How and When You Should Write It

by Thomas Betts Follow 48 Followers on  Oct 02, 2018

Most people would say they want readable code, and may even prefer readability over functionality. But when it comes down to asking people to define readability, opinions will start to diverge. At Explore DDD 2018 , Laura Savino covered why we want readable code, what it really means to be readable, and when readability absolutely must take priority over other considerations.

Michael Feathers Wants Error Elimination to Be a Design Driver

by Thomas Betts Follow 48 Followers on  Sep 21, 2018 1

Michael Feathers finds errors fascinating, but acknowledges that most developers don't spend a lot of time focusing on them. He also thinks most error handling is kind of giving up. Although best known for his books about working with legacy code, Feathers used his keynote presentation at Explore DDD 2018 to discuss how eliminating errors can be a design driver for software systems.

How No and Low Code Approaches Support Business Users and Professional Developers

by Ben Linders Follow 28 Followers on  Jul 12, 2018 2

No code approaches aim to support business users in developing and maintaining their own applications, where low code simplifies the developer’s work and makes them more productive. Both approaches enable faster development at lower costs. As the distinction between these approaches is becoming smaller, business users and developers can team up and use them together.

Business Processes, Long-Running Services and Microservices

by Jan Stenberg Follow 37 Followers on  Jun 28, 2018 2

During recent years domain events are increasingly being discussed, but we should be discussing commands just as much, Martin Schimak explained at the recent DDD eXchange 2018 conference, where he covered events, command and long-running services in a microservices world, and how process managers and similar tooling can help in running core business logic.

Strategies for Decomposing a System into Microservices

by Jan Stenberg Follow 37 Followers on  Jun 21, 2018 2

A couple of years ago, Vladik Khononov and his team decided to start using microservices, but a few months later they found themselves in a huge mess. They concentrated on new cool technologies instead of thinking about how to decompose a system into microservices — finding the boundaries and where different functionalities should be located among these boundaries.

Designing Reactive Systems Using DDD, Event Storming and Actors

by Jan Stenberg Follow 37 Followers on  Mar 27, 2018

Domain-driven design (DDD) is often used for finding boundaries (bounded contexts) around microservices. But everything in domain-driven design (DDD) is not good for microservice, Lutz Huehnken claimed in a presentation at microxchg 2018 in Berlin where he discussed how DDD, Event Storming and the Akka-based Lagom framework can be used to build reactive systems.

QCon London: Asynchronous Event Architectures with or without Actors

by Jan Stenberg Follow 37 Followers on  Mar 13, 2018

Synchronous request-response communication in microservices systems can be really complicated. Fortunately, asynchronous event-based architectures can be used to avoid this, Yaroslav Tkachenko claimed in a presentation at QCon London 2018, where he described his experiences with event-driven architectures and how Actors can be used in systems built on this architecture.

Finding Bounded Contexts Using Domain Storytelling

by Jan Stenberg Follow 37 Followers on  Feb 14, 2018

When working with Domain-Driven Design (DDD), bounded context is a core concept. Domain storytelling is a way of finding how people and systems work together within a domain which then can be used to identify the bounded contexts and how they are interconnected, Stefan Hofer and Henning Schwentner explained at the recent DDD Europe 2018 conference in Amsterdam.

Retroactive and Future Events in an Event Sourced System

by Jan Stenberg Follow 37 Followers on  Feb 09, 2018

When Thomas Pierrain started a new project with an asset management company, one important requirement was the ability to go back in time to understand why they took decisions that today look strange. At the recent DDD Europe 2018 conference in Amsterdam, Pierrain discussed his experiences when building an event sourced system that included some temporal challenges.

Evolving CQRS and Event Sourced Systems

by Jan Stenberg Follow 37 Followers on  Feb 07, 2018

After talking with people about upgrading of CQRS and event sourced systems, Michiel Overeem came to the conclusion that many working with event sourced systems lack an understanding and don’t know how to approach the problem. At the recent DDD Europe 2018 conference in Amsterdam he described how this was a trigger for him to do an exploratory research on how to evolve this kind of system.

Eric Evans: Practicing Domain-Driven Design

by Jan Stenberg Follow 37 Followers on  Feb 06, 2018

For Eric Evans, who gave a keynote at the recent DDD Europe 2018 conference in Amsterdam, it’s important to explore and practice building software. He enjoys working with strategic patterns in Domain-Driven Design (DDD), but what he finds really interesting is taking a difficult domain and reason about it differently; breaking out of the mental box trying to find new concepts.
