In his new post, Jason Bloomberg introduces two types of services – Entities and Tasks, and explains the role each type of services plays in building SOA systems.
Eclipse DemoCamps have been organized around the world over the months of May and June to cover some of the new features of Eclipse Galileo. Today, the London DemoCamp was held at SkillsMatter, presenting NatTable, a high-performance SWT table with extended features, a retrospective of JQuantLib's experiences of moving to OSGi and a demo of Xtext, a powerful text-based DSL modelling tool.
Adobe has announced another step forward in the Flex eco-system with the beta release of Adobe LiveCycle Data Services 3 (LCDS).
Major features of “Oslo” May 2009 CTP are: “Quadrant”, a visual modeling tool, changes of the “M” language specification and the addition of predefined domain models to speed up development.
In this interview Joseph Yoder talks about the Adaptive Object Model (AOM) architecture, a software architecture for easily adapting to changing business requirements.
Data, Context and Interaction : A New Architectural Approach by James O. Coplien and Trygve Reenskau
James O. Coplien and Trygve Reenskaug have recently introduced a new architectural approach to OOP based on Data, Context and Interaction pattern. It should allow capturing user mental model in terms of behavioral requirements, something that classic OOP fails to do. The article, that triggered many reactions and critics, provides insights into DCI using concrete examples to show its advantages.

This article introduces RGen, a modeling framework inspired by openArchitectureWare and technologies like the Eclipse's EMF. RGen uses internal DSLs for defining metamodels and offers a full modeling stack for Ruby.
In this presentation recorded during QCon SF 2008, Tim McCarthy talks about preserving the purity of the domain model while using frameworks. Frameworks can be very useful when developing applications, but they can present some pitfalls, mudding the domain, if they are not used properly. The presentation is targeted at developers.
In this article, Andreas Kaltenbach explains how Model-Driven Software Development (MSDS) can help solving backward compatibility problems when creating a newer version of a software which can mean a new API or a new database schema that old clients cannot use. MSDS is used to negotiate the differences between versions to ease the upgrading process.

Sponsored by the Eclipse foundation, in conjunction with Sybase, Cloudsmith, Actuate, Itemis and WeigleWilczek, there were eleven presentations and four short talks by members of the banking and Eclipse communities.
This article proposes a new Message Type Architecture to help manage the message formats in a SOA. The approach based on two related DSLs, one for the Enterprise Data Model and one for the Message Types, promotes reuse and helps aligning the Data and SOA governance processes.
In this presentation filmed during OOPSLA 2008, Janos Sztipanovits attempts to tackle the complexity of large scale systems integration. Software, systems and control engineering converge in such systems, raising the integration challenges and demanding a new approach to model-based design.
