Command Query Responsibility Segregation (CQRS) is an architectural style that makes a clear distinction between commands, which tell an application to do something, and queries, which are requests for information from an application.

Events play an important role in the synchronization of application state resulting from executed command.
Applying a CQRS style architecture involves the development of quite a lot of “plumbing” code: event dispatching, asynchronous event processing, transactions, etc. cqrs4j, an Apache 2 licensed open source framework, takes care of all the plumbing for you. Read on to find out how…

In this blog post I am writing down the steps I took to create a new grails application. Maybe it can be of help to other that want to start using grails.

I am, of course, going to use some nice grails plugins, I will mention them all and give some details about the steps I took to make them run. Some of the plugins are:
- DBUtil
- Navigation
- grails-ui
- joda-time
Comments, questions and feedback are of course welcome.
