OK. Interface needs a lot of work.
This app has most of the modelling features needed. The interface is not very friendly. You continually have to click the + button to add anything. The table columns are on a seperate screen than the map. I was hoping to interactively do database design work, however with the constant switching between columns and maps it was much easier on paper. There are many other interface issues, handlebars that block text making it impossible to see, small fonts, too much wasted space around text and column definitions, etc.
To it’s credit there are a lot of DB modeling features, just needs a more interactive interface. If you ar looking to document your data model this app might work. If you are willing to spend some time working around the interface I am sure it will have the features you need for modeling. For design work it is just too cumbersome.
