Scott MacVicar presented on SQLite, an embedded SQL database engine that is serverless, public domain, and has a small footprint. SQLite is used by many applications and devices due to its portability and zero configuration. SQLite 3 introduced improvements like 64-bit row IDs, UTF support, and improved concurrency over SQLite 2. Benchmarks showed SQLite 3 generally outperforming MySQL in tests for insert, select, update and delete operations.
