Hello, I never used visual paradigm before, and im pretty fresh in UML.
I wanna make model for my upcoming project, so I need advises how to do that on best possible way.
My project will have 2 big different parts:

  1. windows service : collection data and storing data to sql server. I will use .NET C# for this.
  2. RIA, web application for visualization those data from database. Changing data will also be possible trough this application. It will be written in Flex 3.0.

So, class diagram? Ok, I know I will use that for sure, but which other diagrams will be usefull for me? Any tips?

Thanks alot.

RIA will communicate with database trough web services which will be written in .NET also.
