H2 is a Java SQL database management solution designed for businesses, offering flexibility with both embedded and server modes. In embedded mode, applications access the database directly within the same Java Virtual Machine (JVM) via JDBC, providing a swift connection for single-machine operations. This mode allows for persistent and in-memory databases without limiting the number of concurrent database openings or connections. Alternatively, the mixed mode facilitates access for multiple applications running in separate processes, combining the benefits of embedded and server modes while maintaining optimal speed for local connections.

Targeting a diverse audience, H2 is suitable for mid-sized businesses, small enterprises, nonprofits, and government organizations. It supports English and integrates seamlessly with various applications like DataGrip and New Relic. H2 provides extensive documentation for training purposes, ensuring users can effectively manage their database operations without the need for extensive external support. This makes H2 a versatile choice for organizations seeking efficient database management solutions.
