一種基于BerkeleyDB的嵌入式流媒體存儲系統(tǒng)的設(shè)計

論述了一種以Berkeley DB 為數(shù)據(jù)庫內(nèi)核的嵌入式流媒體存儲系統(tǒng)的設(shè)計方案，該系統(tǒng)以
改進的dosFs 文件系統(tǒng)為底層物理存儲引擎，通過數(shù)據(jù)庫為應(yīng)用程序提供數(shù)據(jù)存取接口，確保了數(shù)據(jù)的安全性和完整性，提高了數(shù)據(jù)檢索的精度和速度。

An Embedded Streaming Media Storage System Based on Berkeley DB (Information Engineering University, Zhengzhou Henan 450002, China) LI Li-Qun, ZHOU Shan, QI Wen-Ya, ZHAO Xin Abstract: This paper presents the design and implementation of a streaming media storage system based on Berkeley DB. The performance and reliability of dosFs filesystem were improved in application space so that to make it a robust storage solution of video surveillance system. Efficient indexes were also created to support complex content management and data retrieval. The usage of database guarantees the security and integrity of streaming media.
