## Resource

SQLite is everywhere—in your phone, browser, and car—yet it rarely gets the spotlight. In this episode of The Programming Languages Podcast, Lucas and Luna explore why SQLite's zero-configuration, serverless design makes it the world's most deployed database engine. They dive into its unique architecture: a single-file database that uses B-tree storage and a carefully designed locking protocol to handle concurrency without a separate server process. Lucas explains how SQLite's atomic commit and rollback work via a journal file, and why its decision to eschew client-server networking makes it incredibly reliable for embedded systems. They also discuss the surprising scale—SQLite can handle terabytes of data and hundreds of concurrent readers—and its role in mobile apps, aviation software, and even space probes like NASA's Mars rovers. The episode addresses common criticisms, like limited write concurrency, and clarifies where SQLite shines versus PostgreSQL or MySQL. Listeners will walk away understanding why SQLite is the unsung hero of modern data management. #SQLite #EmbeddedDatabases #DatabaseInternals #BTree #ZeroConfiguration #Serverless #MobileDev #AviationSoftware #MarsRover #PostgreSQL #MySQL #Concurrency #ACID #AtomicCommit #StorageEngine #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
