I am writing a school paper on Pentaho. I need to clarify some concepts about Pentaho. I keep reading that Pentaho is a Process centric, solution oriented suite.

I played with Design studio and created an Action sequence and published on the server.

My questions :
Is it fair to say that
1. An action sequence models a process ?
2. A solution consists of action sequence(s) ?
3. Solution engine intercepts the action sequence and routes the requests to components ?

I will really appreciate some feedback.
