Sometimes I need to draw a quick ER diagram and I do not want to spend too much time considering the layout, but rather just want to visualize it.
The other extra what I need that on DB theory class we computed, inferred ER model from functional dependencies. It was a quite complicated algorithm. Is it something like that on internet? So the input could be also the list of the dependencies.
It can be a mobile, desktop, or a web-app.
