Introduction to Notification Services

I have been a Core Server Side SQL Server DBA for more than half a decade. This was the first application side task that I handled from the SQL Server front. I would like to thank my friends Chakravarthy and Poornima for giving me this wonderful opportunity to work on Notification Services. I dont claim that this document would give you all that are needed to work with Notification Services. It just gives you a brief idea of what it is and how you can create a simple notification service application.
