phpmaster | REST - Can You do More than Spell It? Part 1: "As I’ve noted above, REST is not a true architecture and it doesn’t force you to use certain tools or protocols. But most implementation use HTTP, primarily because of it’s simplicity. Every protocol has operations defined in it that perform the CRUD (Create, Retrieve, Update, and Delete) work required when data is involved. HTTP uses the four basic operations GET, PUT, POST, and DELETE to do it’s CRUD work."
