Founder of Airtable here--Airtable is actually a relational database with foreign key relationships (the technicalities of which are abstracted away from the user). It's designed specifically to be somewhere between the accessibility of a spreadsheet and the customizability/structure of a Filemaker/Access/Force.com, all with a much more modern UX and collaboration experience. Airtable.com/product or Airtable.com/templates offers some more context!
