SQLite

As a free and open-source embedded database, SQLite simplifies data handling by integrating directly into your application without external dependencies. It's designed for scenarios where a full database server is unnecessary, providing a compact yet powerful alternative. The engine is public domain, so you can use it freely in any project, commercial or otherwise. SQLite's reliability is proven in high-stakes environments, from financial software to mobile apps, thanks to its extensive testing and fault tolerance. It supports most SQL standards, enabling complex queries and transactions without the bloat. This makes it an excellent choice for applications that need local data storage with minimal footprint and maximum control.
