You don't mention where you're at. You're describing a major part of Software Engineering. Most reasonable university/college SE 101 courses will focus here. Which is to say, if you haven't (or it's been a while), check reading lists for university SE classes and pick the ones that focus on modeling. steer clear of process/agile material. Commonly used and recommended books would be GoF (if you're not familiar with the patterns already), Code Complete, and The Pragmatic Programmer.
