Hi All,

I've started a new project where I'm writing a WPF business application, but I'm having trouble with the design. The database was easy to put together, but I'm not sure how I have to go about the designing the application itself.

The main thing that I find hard is the code design. I've decided that the MVVM pattern is very applicable for this application, but how do I go about deciding what classes to build and how things go from there?

Does anyone have some guidelines I could use?

This is a standard business application that just stores and retrieves data. Some data queries will also need to be performed.
