Richard Hipp, the creator of SQLite, shares his story of developing the database engine, from its humble beginnings as a side project to its widespread use in various industries. SQLite was born out of Hipp's frustration with the Informix database while working on a project for the US Navy. The database engine has undergone significant testing, with billions of tests run before each release, to ensure its reliability and resilience. Today, SQLite is used in numerous applications, including web browsers, phones, and commercial planes.
