My TechEd Europe Schedule

Presentations, , , ,

 

TEEU_2014_I’m speaking_1I’m so very excited to be heading to Barcelona shortly for TechEd Europe. You may or may not be aware of my dashed hopes last year when I was scheduled to speak at TechEd Europe in Madrid. But when I found myself stuck in the Chicago O’Hare airport on my 2nd day of travel, only to be told I wouldn’t get to Madrid until Thursday afternoon (after 4 days of travel) it was time to turn around and go home. I also had scheduled a post event side trip to Barcelona – this too, I canceled.

I was a little surprised that TechEd was willing to try again considering my bad history but I will be speaking at the 2014 version of the event.

Not only am I looking forward to my first ever trip to Spain and the amazing city of Barcelona, but it will be my first opportunity to meet so many developers that I’ve never met before.

My Session

My talk is on Friday, Oct 31 at 12-1:15pm. Yes, on Halloween!

Entity Framework Model Partitioning in Domain-Driven Design Bounded Contexts
Bounded Context is one of the most critical patterns in Domain-Driven Design (DDD). While you shouldn’t have to worry about your data persistence while you are modeling your domain, it is still worrisome to follow DDD patterns not knowing how you’ll get your ORM to fall in line when it’s time to implement the data layer. Entity Framework sample solutions have a long history of creating one huge model to map to one huge database to satisfy all of the needs of your application. In this session we look at patterns using Entity Framework that will support not only multiple bounded contexts in your software but even those areas that are satisfied with pure CRUD logic. You also see patterns to bridge the divides between those bounded contexts when implementing the data persistence with Entity Framework.

Getting the Most Out of My Session

Dino Esposito will be doing a relevant talk on Tuesday that will be useful if you are new to Domain-Driven Design.

DEV-B211 Architecting and Implementing Domain-Driven Design Patterns with Microsoft .NET  Tuesday, October 28 1:30 PM – 2:45 PM Room: Hall 8.1 Room G

I’d also recommend watching the Domain-Driven Design Fundamentals course that Steve Smith and I created for Pluralsight. It’s about 4 hours long and is a great first look as well as a refresher on some of the key concepts of DDD. You’ll definitely get a lot more out of my talk if you’ve seen this in advance. If you don’t have a subscription to Pluralsight, send me a note and I can get you a 30 day trial code.

Where to Find Me

Here is my current schedule. This does not list talks I plan to attend, but the opportunities I will have to meet people and geek out! Smile

So much bling, I just can’t choose!

A Pattern for Sharing Data Across Domain-Driven Design Bounded Contexts

Data Access, DDD

My latest MSDN Magazine column  – October 2014 issue – has just gone live.

A Pattern for Sharing Data Across Domain-Driven Design Bounded Contexts
Julie Lerman explores a way to mirror data as one scenario for sharing data across DDD bounded contexts.

Even though the solution is available for download, it involves installing and running RabbitMQ and learning my way around the server’s UI. For me that was a fun and almost freeing step of building the solution. It even meant installing Erlang on my laptop. Lots of fun but lots of learning curves.

But it may be more than some readers want to commit to. So I recorded a video of me debugging through the solution so that you can see how it works.

I recommend reading the article first and watching the Domain-Driven Fundamentals course that Steve Smith and I created for Pluralsight will really help. If you don’t have a Pluralsight subscription yet (really?) send me a message through my contact form and I can hook you up with a free trial. Warning…can lead to addiction.

Anyway, here is the video. There is no sound…I’ve used captions to explain. [youtube http://www.youtube.com/watch?v=N55t2g0cRRQ?rel=0]
