I thought the advice from people like Udi and Greg was that CQRS is overkill for CRUD. And also that why use event stores if you don't need them? I guess in your case you do need them. Looking forward to future posts. I don’t know… I thought the advice from people like Udi and Greg was that CQRS is overkill for CRUD. And also that why use event stores if you don’t need them?

Hopefully lower the learning curve.  Looking forward to reading more. No, I got that.  I think your post should be really helpful for people starting out in CQRS.

But in my series I'd really like to go step by step and not introduce too much "magic" at once. More important than the code or how exactly the code looks like is the fact that we really understand what we are doing and why we are doing it this way.  You are right, most of the ideas are from Lokad.CQRS.

Now you have aggregate, aggregate state, application service for each aggregate.  The "When" is taken out of the aggregate and moved into the application service. The aggregate then has more traditional looking methods in it. He also made the engine rebuild the views from the event stream if needed on start. Very awesome.  I am 2/3 done with release one on this architecture.  I have to say that it has increased the  joy of programming.  Before I started, I thought CQRS looked like a good fit for my project, knew it was powerful, but until I actually dug in and started using it, I did not realize how powerful and frictionless it could be.   Lokad Cqrs had a bit of a learning curve.  In fact, it wasn't my first choice. Looked to complicated and I didn't really understand the value of having the aggregate and state broke out.  Thought that was just extra work. After looking at other frameworks and then writing my own simple framework, I kept coming back to Lokad Cqrs and started to understand more some of the decisions that where made. I figured why reinvent the golden wheel. Might as well dive in and learn Lokad. Smartest decision I ever made.  The read model almost becomes an after thought. If at a later point I decide that the read view should add another field, I add that to the model and as long as I have captured that information in an event, on the next restart of the project, it auto-magically appears, populated from the history contained in the event stream. Almost makes me giddy.  Too easy. I must say, Rinat Abdullin must be some sort of evil genius. And since much of Lokad.Cqrs is based off of work and ideas brought forth by Greg Young, I guess he's okay too.  It looks like you are basing most of your examples off of an older version of Lokad.Cqrs.  You should check out the latest.  Rinat split the aggregate out a little.

Once you have the events you can get a lot out of them!  Yes, even in CRUD scenarios we apply the same patterns. Once you have the events you can get a lot out of them!
