I will speak about StreamInsight at Miracle Open World in Denmark

Beat the stock market with StreamInsight

StreamInsight is one of the main news of SQL Server 2008 R2. It's a platform for Complex Event Processing (CEP) that enables processing of high speed event streams using familiar tools such as Visual Studio, C# and LINQ. CEP is a technology that is increasingly used for algorithmic trading, targeted ads at websites and real-time Business Intelligence. In this session, you will get a 60 minutes introduction to how StreamInsight works and a demo of how to build an application that handles data in near real-time from sources such as Twitter, Facebook and financial markets. 

Miracle Open World will be held during 14th - 16th of april in Billund, Denmark. For more info and registration, see this link:
