With its combination of robust SQL features, support for Java technology, security, and embeddable, pure Java architecture, Derby is the data management product of choice for data-driven Java applications. This unique combination of technical capabilities allows application developers to build data-driven applications that are pervasive run anywhere , deployable downloadable , manageable, extensible, and connectable. There are a few right now, but Cloudscape isn’t one of them. These characteristics make it easy to download Derby applications together with their database or run them from a CD-ROM.
