Detailed Description of HyperSQL Database Engine 1.9.0


HyperSQL Database Engine HyperSQL Database (HSQLDB) Engine is the leading SQL relational database engine written in Java. It has a JDBC driver and supports a rich subset of ANSI-92 SQL (BNF tree format) plus many SQL:2008 enhancements. It offers a small, fast database engine which offers both in-memory and disk-based tables and supports embedded and server modes. Additionally, it includes tools such as a minimal web server, in-memory query and management tools (can be run as applets) and a number of demonstration examples.

HSQLDB is currently being used as a database and persistence engine in many Open Source Software projects and even in commercial projects and products. In its current version it is extremely stable and reliable. It is best known for its small size, ability to execute completely in memory, its flexibility and speed.
