I like most about this software it has good graphical representation with which you can easily visualize your system design for any project. It also provides various options to view all aspects in one screen instead of having multiple tabs open. The UI looks clumsy at times specially when working with large designs. There are other better tools available out there but still i recommend using Unicom architect because many features are provided as addons or extensions so they have more functionality than others. For designing ERP Systems this is best option out there. This helps me understand my requirements from an architectural perspective.
