what is sql

Someone ask: what is sql

Caveman say SQL is tongue for talking to data cave. Tribe put info in big stone tables, like baskets for mammoth meat, berries, spear parts. SQL tell cave what to find, add, change, or remove. Caveman might say, “show all berries from red basket,” and data cave bring back matching ones. It work with commands like SELECT, INSERT, UPDATE, and DELETE. SQL strong because many different data caves understand same tongue. Cave wisdom: SQL is not data itself; SQL is key that let Caveman ask data cave for what hide inside.
