All of these tools specialize in managing the tables and tables of information that are routinely dispatched to relational databases. These are the lifeblood of businesses, and it's no surprise that there are a number of approaches to corralling this data.
Forms over function
The simplest tools don't do much, but they can accomplish much of what traditional Web sites do. If you want a number of people to fill out their particular row of a database, nothing could be simpler than JotForm, FormAssembly, or Wufoo. You drag and drop fields onto a page until you've got all of the questions arranged in a way that won't annoy the end-user too much. Then you push a button, send out e-mails, hope the people won't ignore the request, and collect the data in a collated file.
