H2 Database Engine is a powerful, feature-rich database with support for advanced SQL features, making it suitable for larger applications and development environments. In contrast, SQLite is a lightweight, portable database ideal for smaller applications and simple use cases, but it lacks some of the advanced features that H2 offers.
