SQLite is a self-contained, high-reliability, embedded, full-featured, public-domain SQL database engine. Unlike traditional database management systems (DBMS) like MySQL or PostgreSQL, SQLite doesn't require a separate server process. Instead, it reads and writes directly to ordinary disk files, making it an ideal choice for:

- Development and Testing: Rapid prototyping without the overhead of managing a separate database server.
