Hi What is the best way to understand the concepts of workflows. is there any site or examples through which i get more grip on workflows.
I think the best explanation is in the Content Server Fundamentals guide which has an entire chapter dedicated to the datamodel and concept of workflows.
This is much older, but good for an overview:

Fabian, I just looked at the PDF and this is very much still current. The core architecture for workflows hasn't changed since the 4.x days. Sure, some objects have been added and the UI updated, but overall... this is a really, really good presentation. It wouldn't take much to update this to 6.5.
