HSQLDB (HyperSQL DataBase) is the leading SQL relational database software written in Java. It offers a small, fast multithreaded and transactional database engine with in-memory and disk-based tables and supports embedded and server modes. It includes a powerful command line SQL tool and simple GUI query tools.

HSQLDB supports the widest range of SQL Standard features seen in any open source database engine: SQL:2011 core language features and an extensive list of SQL:2011 optional features. It supports nearly full Advanced ANSI-92 SQL (BNF format). Many extensions to the Standard, including syntax compatibility modes and features of other popular database engines, are also supported.

The server looks for a 'server.properties' file in the current directory and
loads properties from it if it exists.
Command line options override those loaded from the 'server.properties' file.
