Layers of abstraction Electronics (charge or no charge)->Logic Gates -> Microprocessors (Logic sequence and data, assembly language)->BIOS -> Drivers (device specific lower level operations) ->Operating System ( APIs/system calls, processes, files and memory) -> Database (Tables) -> Applications (Objects, Fields, Flows) -> UI/Business function API.

Brilliant deck, explanation, language and delivery, thank you! First half of the talk little fast, but we have the luxury to pause to chew it and digest it better, thanks to technology :). Though it 6 years old presentation, core and vast majority of it would be still relevant. Great thing is that NoSQL databases can be (probably is) used for various pieces of data underneath but it is completely insulated and abstracted out to customers and developers!
