CRUD

CRUD stands for Create, Read, Update and Delete, refering to the four basic operations we perform on data stored in a database. Almost all internet consumer-related software uses CRUD; you use it every time you ask an application to take your new data or modify the existing one. In the context of the Mybooks App application:

• Create: This would consist of a function which we would call to create and store a new book in the database.
• Read: This would consist of a function which would be called to see all (or a subset) of stored books.
• Update A function to call to make changes to an already existing book.
• Delete: A function to call to remove an already existing book.

tip

CRUD often corresponds to the HTTP methods POST, GET, PUT, and DELETE, respectively.
