Java DB is Sun's supported distribution of the open source Apache Derby 100% Java technology database. It is fully transactional, secure, easy-to-use, standards-based — SQL, JDBC API, and Java EE — yet small, only 2.5 MB.

Main Features:

• Departmental Java client-server applications -- Java DB comes with 24 x 7 support and transactional protection against data corruption and systems crashes.
  
• Java application development and testing -- Java DB is full-featured, easy-to-use, and free under the Apache license. In addition, Java DB runs everywhere from laptops to mainframes.

• Embedding in applications -- Developers and end-users don't need to buy, install, administer, or even be aware of the database hidden inside the application.
  
• Multi-platform use -- Java DB is portable because it's 100% Java. In addition, Java DB complies with the SQL and JDBC standards, making it easy to migrate applications from Java DB to other databases.
  
• Use within browser-based, Web (2.0) applications -- Distribution is easy due to one-click installation. Secure local data storage means applications run online and offline.
