HSQLDB (HyperSQL Database) is a relational database management system written in Java. It is open-source and widely used for its small size, ease of use, and compatibility with Java applications. HSQLDB supports standard SQL syntax and JDBC (Java Database Connectivity) API, making it compatible with a wide range of Java-based applications and frameworks.
Key features of HSQLDB include :
* Embedded and Server Modes : HSQLDB can run in embedded mode within a Java application or as a standalone server accessed over a network.
* In-memory and Disk-based Tables : It supports both in-memory and disk-based tables, offering flexibility in data storage options.
* Transactional Support : HSQLDB provides full ACID (Atomicity, Consistency, Isolation, Durability) transaction support, ensuring data integrity.
* Small Footprint : HSQLDB is lightweight and has a small footprint, making it suitable for use in resource-constrained environments.
* Compatibility : It supports a wide range of SQL standards and is compatible with various JDBC drivers, allowing easy integration with Java applications.
* Cross-Platform : Since it is written in Java, HSQLDB is platform-independent and can run on any platform with a Java Virtual Machine (JVM) installed.
