On the road to Indigo...( thats Richard Turner..right??) you will pass through Yukon Service Broker. The Service broker is a set of services on the data base layer that provide the framework for distributed, aysnchronous message based database applications.
I got really excited when i saw this, we can actually build service oriented applications today just by writing a couple of T-SQL statements. Yes you read it right. Now you can decouple your applications and distribute them over time spans and geographies and export them as services on a network just by using T-SQL.
Its actually powerfull stuff. Pat Helland ( of Metropolis Fame) is the architect of this rather cool piece of infrastructure.
If you want to learn the aspects of Indigo, but dont know where to go...learn the concepts by using Yukon Service Broker. Yukon is in its second beta and comfortably stable.
Get started on Service Broker, get a feel of how a SOA app should work...experiment...burn the midnight oil...its well worth the investment.
Get back to see what i post as i learn the Service Broker based apps.
