Would you like to learn all about system building and architectures with Domain Driven Design? Join this course on CQRS, Domain Events, Event Sourcing and how to apply DDD with Greg Young!
The largest problem many run into with Domain Driven Design is in getting the abstract concepts implemented in a concrete way. Many of the stereotypical architectures people use actually make it impossible to apply DDD.
This CQRS course will help you avoid this. You will learn all about Command Query Responsibility Separation (CQRS), Domain Events, Event Sourcing and how to effectively apply DDD within an organisation.
Learn how to:
- Apply DDD
- Use CQRS
- Understand Domain Events
- Apply Event Sourcing

"One of the best courses I have been on. Lots of real examples and very engaging for an intense course on a big subject. Great to hear how ideas have evolved and how dependent on different scenarios, architectures may be appropriate."Julian Walls on 11th Jun 2015
"Learned a whole lot. The anecdotes and experiences really help in grasping the topics."December '14 course delegate on 16th Dec 2014
"Very enjoyable - I'd do it again."Neil Robbins on 10th May 2010
"Superb course - good practical examples backed up with solid theoretical knowledge. - Finn is Development Manager for Fundraising Innovations Ltd"Finn Newick, Fundraising Innovations Ltd on 9th May 2010
"have had the pleasure of spending a 2 day course and many geek beers with Greg Young talking about Domain-Driven Design specifically focussed on the Command and Query Responsibility Segregation (CQRS) pattern. Greg has taken Domain-Driven Design from how Eric Evans describes it in his book and has adapted mostly the technical implementation of it. Command Query Separation (CQS) was originally thought of by Bertrand Meyer and is applied at object level Bertrand defines CQS as: every method should either be a command that performs an action, or a query that returns data to the caller, but not both. In other words, asking a question should not change the answer."Mark Nijhof on 12th Nov 2009
