Crud – Part I

Julien Klepatch

We will start a CRUD smart contract in Solidity. Crud stands for Create, Read, Update and Delete, and represent a very standard set of data operation that most application needs to do. Once you know these 4 operations, you are well-equipped to develop a large range of smart contracts. In this video, you will learn to:

  • Represent complex piece of data with Solidity struct, similar to Javascript objects
  • Create array of structs
  • Find a specific entry of an array with a for-loop
  • Create and Read in CRUD
