``` import { drizzle } from 'drizzle-orm/better-sqlite3'; import Database from 'better-sqlite3'; const sqlite = new Database('sqlite.db'); const db = drizzle(sqlite); ``` Basically, drizzle wrap each driver like above. OTOH, Drizzle can manage db object in memory? like this: ``` import { drizzle } from 'drizzle-orm' const db = drizzle() // <- in memory ```
