Comments on: What is CQRS? http://www.thedeveloperday.com/what-is-cqrs/ Staying Curious Wed, 01 Feb 2012 07:05:15 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Keith Pope http://www.thedeveloperday.com/what-is-cqrs/comment-page-1/#comment-909 Keith Pope Sat, 20 Nov 2010 18:12:13 +0000 http://www.thedeveloperday.com/?p=649#comment-909 Good to see CQRS mentioned in a PHP context, I think with the push to MVC the modelling/architecture side of things is getting more important. I would slightly disagree that CQRS could not help with legacy apps, you may find you have reached a barrier with scalability of one of your app tiers, for instance the ORM, it may then make sense to migrate these so you can scale more easily. I think one of the great things about CQRS is that you can pick and choose the parts you need, I suppose this is integral to its DDD roots :) Also as we are using dynamic languages generally in a web environment we may not need an ESB like NServiceBus, I have seen examples of atom feeds (currently researching) being used as the bus. You can then use pubsubhubbub to handle the routing and atompub for service discovery.

It's nice input to think about the more general stuff. Thanks for pointing to this. It’s nice input to think about the more general stuff.
