CRUD (Create, Read, Update, and Delete) is an acronym for the basic functions that an application must be able to perform in order to be considered “complete.”
For example, if you want to develop a basic phone book app. In order to feel like a “complete” application, the user should be able to perform at least four operations: create new entries access the information of each entry, edit and save the existing information, and remove the old and unnecessary entries from the application. In this example, the phone book is essentially working as a database, and this CRUD is used to describe what an application with a database should be able to do.
