Astah in Action

A few years ago I was looking for a tool to help me to draw UML diagrams. When I was in college, my teachers recommended enterprise platforms, but I was looking for a faster and simpler tool. Then I found Astah, and it was exactly what I wanted. Astah is cross-platform, which enables me to use it both on my Linux and Windows, and this has helped me a lot!
