SBO's, what and how?

I received some feedback on my previous blog on TBO's: http://www.docbyte.com/blog/creating-custom-tbo and a question that came back was: what are SBO's, and how are they connected with TBO's?

So in this tutorial, I'll try to do the following things:

• what is an SBO?
• how do you create an SBO?
• how do you use an SBO?
• provide a sample project

An SBO is a Service-Based Business Object.

Creating a custom TBO

As my first blogpost, I decided  to start off easy and do a (modified) repost of my blogpost on the EMC Community site on how to develop a custom TBO: https://community.emc.com/people/BartThierens/blog/2010/03/15/steps-to-create-a-custom-tbo
