基于interMedia的BLOB对象高效存取机制探析

Efficient Accessing Research for BLOB Object Based interMedia

针对教学活动中非结构化核心数据集成管理,分析了Oracle interMeida技术框架和工作原理,以及系统架构设计,提出了运用PL/SQL存储过程及JavaBean中间件技术,提高系统I/O效率的方法,实现了图像、音视频及文档这类BLOB非结构化类型数据在Oracle数据库内高效管理及快速存取,为现代远程教学中对多媒体数据有效管理、基于内容的信息检索等应用等提供了有益的探索。

According to the non - structured kernel data management in distance education, this paper analyses the architecture and principle of Oracle interMedia as well as the design of its application system framework, puts forward a convenient management method to enhance the system I/O efficiency by applying PL/SQL store procedure and JavaBean middleware technique. And in the end carries out the efficient management and the quick readwrite about BLOB non -structured type data such as image, audio and video files stored in Oracle data- base. This method will greatly benefit multimedia data management in current distance education and content - based information retrieval, etc.
