Web sites are generally, mostly static content without a whole lot of user interaction whereas web applications are usually designed to create content dynamically and are highly interactive. But there is a ever changing gray area in between. So is our new web framework meant for building web sites?
If your web site (or a part of your web site) is very dynamic then it might actually behave more like an application than a web site. If that's the case, then Real Studio might be appropriate. If, on the other hand, your web site is very static, then Real Studio is almost certainly not appropriate.
Is Real Studio designed for building web sites? No, it's not. But your web site might function more like a web application than a website, in which case perhaps Real Studio's web application support is a good solution for you.
