CDO Enters the 3rd Dimension

Update: The new room is 
Ballroom B+C
(not D, as in the printed schedule!)

EclipseCon is near and I'd like to invite you to attend Martin's and my talk CDO 3D on Monday shortly after lunch time.

As you may know or not, CDO is a runtime environment for distributed shared EMF models. Especially for organizations with huge models (e.g. the NASA, banks like the UBS AG, etc.) CDO is indispensible and has become sort of modeling mainstream in the past years.

Although I've always invested a lot into cool animated Powerpoint slides and although CDO comes with really new functionality each year, we've recognized a slight tendency of the conference audience to decide for parallel talks about completely new modeling technology, if they were forced to choose one. This fact (and the guy who shouted "next year we get Pixar Studios" after my last EclipseCon talk) has made me think about new ways of presenting a complex distributed technology. That's why this year's talk is titled "CDO 3D".

We will have no Powerpoint slides anymore but fully focus on real-time demos of a distributed system with a CDO model repository server and two CDO client applications. The client applications have RCP user interfaces, as well as a self-made scripting console that we will use to demo the API usage of CDO and the immediate influence of local CDO calls on the entire system.

In addition we've developed a 3D visualization frontend, that renders the contents and activities in multiple Java virtual machines into a 3D canvas in real-time. We've instrumented these VMs so that the frontend can even visualize the method calls between the Java objects and the network traffic between the VMs. This diagram outlines the basic architecture of our presentation system:

Of course we'll also talk about some of the cool new features in CDO 4.0 like OCL queries, Blobs and Clobs, cross referencing and referential integrity checks, fail-over cluster and the brand new backend integration with MongoDB. I'm looking forward to see you in Santa Clara!
