Zoho Creator is like Microsoft Access online
I am by no means an MS Access adept, but I have worked with databases since the heyday of mainframes. I like Zoho.com quite a bit. It is on the web, free, and not all that tricky to use. Why do things the expensive way if you can do it with Zoho? There is a movie if you check out the link back to Lifehacker.
Set up your database's fields (like for an address book: Name, Address, City, State) and then build drag and drop custom entry forms with different input types like radio buttons, check boxes and dropdowns. Ambitious types can add custom logic to the application using the script builder, and the whole shebang can be added to your web site or blog (say, for a feedback form or survey). Looks like a nice way to create a powerful interface to customized data, instead of wrangling with boring spreadsheets.
