摘　　要：数据作为一种资产其蕴含的价值越来越重要,把收集到的数据存储下来用于后续的数据分析与挖掘具有重要意义。论文针对海量的海洋监控视频,提出一种存储方案来满足查询需求。在此基础上,文中提出一种索引结构RB-Tree,使得基于该索引可实现海量数据的快速检索。此外,文章从理论层面对索引查询的时间代价进行分析,并与基于传统B+Tree、R-Tree索引的查询时间代价进行对比,说明RB-Tree在海量视频数据管理上的优势。The value of data which is considered as a kind of asset has become more and more important. Storing collected da？ta for subsequent analysis and mining has great significance. In this paper,a storage scheme to meet the query requirement for mas？sive ocean surveillance video is proposed. Propose the index RB-Tree to realize fast query over massive data is also proposed. Be？sides,the paper theoretically analyzes the time cost of query. The query cost of the RB-Tree with the traditional B＋Tree and R-Treeto indicate our advantage on massive ocean video data is furtherly compared
