You can create a database with this visual scheme editor (graphical environment) and you can export to MySQL, MSSQL, SVG,... etc. Flowdbeditor is a drag'n drop GUI and inAir data editor. (CHROME). Pure Javascript.
You can use the third control :) your voice. (WEB Speech API based voice recognition.) Two language (hungarian and english)

It is a simple project but maybe provide much food for thought. I developed for own use, but other peoples started use. The InAir editor was an important part of this project for me, because I can tried the database behaviours. Other exciting part is the voice recognition capability. In a silence room you can speak to the flowdbeditor, and you can feel like an another assistant help to you. It is interesting feeling. :)
The project finished but I develop new features occasionally.
