A few months ago I visited an interesting web site. It was a web to create data models (online) and web services (rest or soap) and deploy them at the moment, all without coding any server or SQL. I think it's interesting for creating prototypes when I create iOS apps, as many of them are just web service consumers. The problem is that I forgot the name of the website. Do you know that website or similar services? Thanks.
Stackmob is one such service that allows you to create models on their servers easily.
