You may hear the expression “CRUD” used in relation to databases. And if you haven't, you have now. CRUD is a acronym fro Create, Read, Update, and Delete—the four main operations that are done on databases.

BTW, the book consistently uses “a” as the indefinite article ahead of “SQLite”—most probably because they assume a pronunciation of “sequel lite.” The primary author of “SQLite” sees things differently, so the indefinite article should be “an”.
