different HTTP functions to interact with data. Table 6-2
lists some of the most common HTTP functions and their
associated use cases.

HTTP functions are very similar to the functions that
most applications and databases use to store or alter
data, whether it is stored in a database or within an
application. These functions are called CRUD functions;
CRUD is an acronym that stands for CREATE, READ,
UPDATE, and DELETE. For example, in an SQL
database, the CRUD functions are used to interact with
or manipulate the data stored in the database. Table 6-3
lists the CRUD functions and their associated actions
and use cases.
