Udi Dahan talks about Command Query Responsibility Segregation (CQRS) and its relationship to Domain Driven Design (DDD). Dahan also discusses his project, the NServiceBus. NServiceBus is an open-source service bus for Microsoft's .NET environment. In many ways, NServiceBus works like Microsoft's Windows Communication Foundation (WCF) and can be used instead of WCF in some cases.
Oren Eini talks about the difficulty to build N-tiered systems that are highly scalable, presenting several concepts – divide and conquer, background evaluation, one way messaging, the single responsibility principle - along with .NET frameworks – NServiceBus, Rhino ESB, Mass Transit, Rhino PHT, Rhino DHT, Raven DB - which help solving the scalability problem.
NServiceBus 3.0 was recently released and InfoQ talked to Udi Dahan, the creator of NServiceBus, about the new features of the latest release. One of which is the RavenDb integration, a fairly new document data store written in .NET and created by Oren Eini (Ayende). InfoQ also took the opportunity to ask Ayende some questions and what the integration means for his own Rhino Service Bus.
