Olivier Auverlot: "At my work (a universitary computer research laboratory), I'm alone to create all applications and databases. I don't know how I could do all the work without it. It's really a very productive software. I can focus on the database schemas and create quickly the user applications with a minimal amount of code to maintain".
John Gondek: "Your software is amazing. I consider myself a novice at PHP and JS and with your software I have a web page that is truly fantastic. Thank you so much ".
