Standardizing on common models for business objects that are exchanged within an enterprise, e.g. Customer, Order and Product together with the attributes and associations they have, might seem compelling but for Stefan Tilkov this creation of Canonical Data Models (CDMs) is a horrible idea which he strongly advices against.
Domain-Driven Design (DDD) is an approach to building software emphasizing collaboration between domain experts, developers and others involved in order to meet business objectives, Naresh Bhatia explains introducing the DDD base concepts exemplifying with Bullsfirst, an example system of medium complexity from the financial trading domain.
The gap in agile adoption between Eastern Europe and the US and Western Europe is becoming smaller. Scrum is the most widespread framework, Kanban adoption is growing and SAFe, LeSS, DAD are trending. The way that companies are transitioning to agile is significantly different in Eastern Europe.
Gene Kim (moderator), Gary Gruver, Andrew Phillips and Randy Shoup have discussed some of the benefits of microservices in a recent online panel.
Behaviour-Driven Development (BDD) is very much about conversations and examples but there is a software design part that can be used to bring BDD and Domain-Driven Design (DDD) practices together, combining the conversional bits with a domain-focused design activity, Konstantin Kudryashov explains in a presentation.
The analysis of competing hypotheses (ACH) method can be used to evaluate multiple competing hypotheses when investigating problems. The method mitigates cognitive biases that humans experience when exploring the causes of problems.
Move as much as possible of the behaviour away from the Entities into Value Objects when working with Aggregates, As more behaviour is needed this is added as new value objects, Paul Rayner recommends in a series of blog posts covering aggregates, entities and value objects, all concepts from Domain-Driven Design (DDD).
Niels Pflaeging, founder of the BetaCodex Network, did the opening talk organize for complexity - how to get life back into work on the second day of the Dare Festival Antwerp 2014. He explained how decentralizing organizations is paramount to increase their performance and agility.
When using Domain-Driven Design (DDD) separating the concerns of a large system into bounded contexts with each context using its own data store there is often a need to share some common data. One way of doing that is to let each context publish events about changes, events that others can listen to, Julie Lerman recently explained in MSDN Magazine.
In lean, we co-design and continuously improve processes and tools to better serve individuals and interactions said Claudio Perrone. Lean views problems as a gap between the current situation and the standard and expectation. Am interview with Claudio about problem solving and learning, and on tools that can be used to apply lean thinking for change in organizations.
Layered systems are an architectural style used essentially to avoid coupling, the biggest enemy of software maintainability, with Ports and Adapters, or a Hexagonal Architecture, an example of such an architecture, Ian Cooper explains in a presentation about architecture styles, specifically the Hexagonal Architecture.
Domain-Driven Design (DDD) together with Onion Architecture is a combination that Wade Waldron believes has increased his code quality dramatically since he started using it a few years back. Using DDD was a kick-off but together with Onion architecture he found his code to be more readable and understandable, and far easier to maintain.
Last week VersionOne and CA Technologies announced that they have integrated their Project and Portfolio Management (PPM) and Agile Project Management (APM) products to provide an enterprise solution which the two organisations say gives users the ability to have a strategic view of a complete portfolio at the executive level no matter what methodology teams might use.
Most of the open source projects we share with you on InfoQ increase the capabilities of another library or technology. MongoRepository is different in that it intentionally limits the capabilities of the underlying library. We’ll let Rob Janssen why it does this in his own words.
CQRS and Event Sourcing provide a clear and concise way to build distributed applications that adhere to the reactive manifesto, Duncan DeVore claimed in a recent presentation sharing his experiences building a distributed application using Akka and Scala.
