This is what Kirill Bondar, the representative of TeamDesk Support, said:
To see it in action, you may want to check TeamDesk application library."
"Its content is managed by our team through regular TeamDesk application that allows editing the title, keywords, descriptions, place images and attach support documents, categorize applications and many more."
As you can see the TeamDesk uses the same approach QuickBase offers. The good news is you can use TeamDesk as back-end database for your site for only $9/month. But one should note this implementation requires knowledge of scripting and is not available in simple wizard-like style as Caspio offers.
