Implementing Domain-Driven Design (DDD) concepts using object orientation principles with state and behaviour often gives you a muddled mutable model, instead building domain objects with only state and behaviour as standalone functions leads to a better realization, Debasish Ghosh claims in a recent blog post.
Independently from each other, Richard Warburton in a presentation, and Mark Seemann in a blog post both talks about object-orientation and the SOLID design principles from a functional programming perspective.
The final version of the Object-Relational Mapping, ORM framework Hibernate 4.3 was recently released and is now a certified implementation of the JPA 2.1 specification, (JSR 338), released in May 2013.
With a long history of data-driven development, Julie Lerman shares her experiences moving into using her skills with Domain-Driven Design in three articles, with examples in C# using Entity Framework
Architecture is about intent, we have made it about frameworks and details, Robert C. Martin, “Uncle Bob”, stated earlier at this year’s DDD Exchange Day in London. Robert refers to a book by Ivar Jacobson from 1992 and brings the original thoughts about use cases into architecture models, e.g. Hexagonal architecture and Clean architecture to improve these models.
The Open-Closed Principle, OCP, part of the object-orientation SOLID principles, was recently criticised by Jon Skeet and Robert Ashton who both believes the principle is doing more harm than good. Robert C. Martin, who identified the principles in the early 2000s, however, defends the principle, arguing that you have to look at the full description, not just the short definition.
Martin Fowler talks about Software Design in the 21st Century split into three short talks, Schemaless Data Structures, NoSQL & Consistency, and finally the value of Software Design.
ModelMapper is an object to object mapping library that eliminates repeatable code for copying objects from one representation to another. By looking at property names it can perform an automatic mapping or hints can be defined that describe precisely the mapping process. It is inspired from AutoMapper which is a similar library for .NET
OMG CEO Richard Soley in a recent interview shares his observations on hype cycle effects on adoption patterns and how it may affect cloud computing like it did SOA. He extolls some virtues of cloud computing for startups and also explains why it may still not be as big a deal for larger businesses, despite the hype.
Akka 1.1 was released with many improvements in performance, Futures and more. The basic Akka also has no dependencies except for Scala 2.9. InfoQ caught up with Jonas Bonér to talk about the current state and the future of Akka.
Should one approach SOA domain modeling starting with informational or functional constructs? Is a canonical data model the answer to standardizing message formats? What are the various stages of SOA information modeling? Experts on Gervas Douglas's SOA distribution list on yahoo groups put forth their views to answer these questions and more.
Robert Harper and Dan Licata, Professors of Computer Science at Carnegie Mellon University, announced last week that they have decided to "eliminate entirely" OOP from the CS introductory curriculum.
The OOP conference (Object Oriented Programming) was held in Munich, Germany, from 24th to 28th January 2011 with “Business Impact through Mastering Change” as its general motto. Despite of its name, the OOP represents one of the largest and long-lasting events on the general field of software engineering.
In a QCon London 2010 interview with Joe Armstrong, the original developer of Erlang, and Ralph Johnson, long associated with Smalltalk, OOP, and Patterns, the question of whther we've gone down the "wrong path" w.r.t. object orientation all these yearrs. Both interviewees suggest that we have, but this is due to flaws in the implementation of object ideas and not the ideas themselves.
