Answer and Explanation

Software that handles data, such as databases, requires the basic functions of Create, Read, Update, and Delete. These four functions are collectively referred to by the acronym CRUD.
In SQL, the UPDATE and DELETE commands correspond to the English names of the CRUD operations for data updates and deletions, respectively. However, creation is performed with INSERT, and reading is done with SELECT.
