The most useful feature of this software is that it's easy to use and understand. It is very simple to create diagrams and models using this program. I do not like how some features are difficult to find in the menus. For example, there is no way to copy or paste an entity from one diagram to another. Also, if you need to make changes to your model, it can be difficult to find where you made those edits. I would recommend this product because it makes creating diagrams and models so much easier than other programs. This program has helped me organize my information better and keep track of all my data.
