與常見的數(shù)據(jù)庫相比，嵌入式數(shù)據(jù)庫具有體積小、功能齊備、可移植性、健壯性等特點(diǎn)，本文分和比較了典型的嵌入式數(shù)據(jù)庫SQLite和Berkeley DB。首先從體系結(jié)構(gòu)、子系統(tǒng)間調(diào)用關(guān)系、任務(wù)執(zhí)行過程等角度對SQLite和Berkeley DB進(jìn)行了詳細(xì)分析，然后重點(diǎn)從數(shù)據(jù)類型、存儲方式、模式、數(shù)據(jù)庫引擎和錯誤處理及加密功能等方面討論了SQLite和Berkeley DB的異同點(diǎn)，最后列舉了一個基于ARM—Linux的SQLite應(yīng)用實(shí)例。

Abstract：Compared with the normal database, the embedded database has some distinct features, such as small volume、necessary functions、portability、 robustness and so on. This paper analyses and compare the SQLite with Berkeley DB, including the architecture、relationship among subsystems and the processing execution. And then, the author discusses the difference between the SQLite and Berkeley DB on data type、 storage method、mode、VDBE and error management. At last ,there is an example of the SQLite applied on the ARM—Linux.
Keywords：SQLite，Berkeley DB，SQL，VDBE
