Derby 是一種功能完備的關(guān)系數(shù)據(jù)庫(kù)，具有能與大型企業(yè)數(shù)據(jù)庫(kù)相抗衡的能力。不要讓它極小的規(guī)模（2 MB）和成本（0 美元）給騙了。
Derby 是純事務(wù)型的，當(dāng)和 J2EE 服務(wù)器的 JTA 事務(wù)管理器一起使用時(shí)，可以參與全局（分布式）事務(wù)。
Derby 數(shù)據(jù)庫(kù)系統(tǒng)（二進(jìn)制文件和數(shù)據(jù)庫(kù)）可以復(fù)制到任何帶有 J2SE JVM 的平臺(tái)，并且無(wú)需重新編譯或作其他修改就能運(yùn)行。
缺省配置下的 Derby 數(shù)據(jù)庫(kù)系統(tǒng)不需要進(jìn)行單獨(dú)的管理。它的引擎在 J2EE 服務(wù)器 JVM 進(jìn)程中運(yùn)行，成為系統(tǒng)集成的一部分。
