Where and how application data is stored in Ethereum?

Ethereum is used to build decentralized applications, a.k.a. DAPPs. These applications exist through small programs that live on the Blockchain, called smart contracts.

Before jumping into the platform and writing a smart contract, it’s really important to understand where your application data is stored. Code execution, servers and programming language are rarely critical to the design of an application. But data –its structure and its security– will constrain our design the most.
