HSQLDB, or HyperSQL DataBase, stands out as a premier SQL relational database system developed in Java. It boasts a compact, efficient multithreaded transactional engine that accommodates both in-memory and disk-based tables, functioning effectively in embedded and server configurations. Users can take advantage of a robust command-line SQL interface along with straightforward GUI query tools. HSQLDB is distinguished by its comprehensive support for a vast array of SQL Standard features, including the core language components from SQL:2016 and an impressive collection of optional features from the same standard. It provides full support for Advanced ANSI-92 SQL, with only two notable exceptions. Additionally, HSQLDB includes numerous enhancements beyond the Standard, featuring compatibility modes and functionalities that align with other widely used database systems. Its versatility and extensive feature set make it a highly adaptable choice for developers and organizations alike.

Welcome to H2, a Java SQL database designed for efficient data management. In its embedded mode, an application can access the database directly within the same Java Virtual Machine (JVM) using JDBC, making it the quickest and simplest connection method available. However, a drawback of this setup is that the database can only be accessed by one virtual machine and class loader at a time. Like other modes, it accommodates both persistent and in-memory databases without restrictions on the number of simultaneous database accesses or open connections. On the other hand, the mixed mode combines features of both embedded and server modes; the initial application that connects to the database operates in embedded mode while simultaneously launching a server to enable other applications in different processes or virtual machines to access the same data concurrently. This allows local connections to maintain the high speed of the embedded mode, whereas remote connections may experience slight delays. Overall, H2 provides a flexible and robust solution for various database needs.
