CRUD
Create, Read, Update, Delete
ELI5 — The Vibe Check
CRUD is the four things you can do to data: Create it, Read it, Update it, Delete it. Literally every app ever made is just CRUD in a trenchcoat. Your AI probably generates CRUD apps 80% of the time.
Real Talk
CRUD represents the four basic operations of persistent storage. It maps directly to SQL statements (INSERT, SELECT, UPDATE, DELETE) and HTTP methods (POST, GET, PUT/PATCH, DELETE). Most web applications are primarily CRUD interfaces over a data model.

DELETE
DELETE removes rows from a table. It is the 'Delete' in CRUD. Like UPDATE, you MUST use a WHERE clause — without it, you delete everything in the table.
INSERT
INSERT is how you add new data to a database. It is the 'Create' in CRUD. You tell it which table, which columns, and what values to put in.
SELECT
SELECT is how you ask a database to give you data. It is the 'Read' in CRUD.
UPDATE
UPDATE changes existing data in a table. It is the 'Update' in CRUD.
