Just to add to my previous post... you could also use it to very quickly create a results page, a search facility with search results, and an article detail page. So, it's not just for entering data into a db.
I prefer to build my own versions of these front end pages though as I really can't be bothered to mess with the resultant css, but I think that's where site assist pro comes into its own. you create your design with that, and then share it with data assist (somebody correct me if I am wrong)!
