摘要
数据库系统中可以存储图像、文档、音频、视频等BLOB数据。基于ADO.Net 2.0所提供的数据访问接口和文件流技术,可以对数据库系统中所存储的BLOB数据进行有效处理。提出数据库系统中BLOB数据的两种存储策略:数据表方式和"数据表+文件系统"方式,并对两者进行了分析和比较,在此基础上基于ADO.Net 2.0对两种策略下BLOB数据处理的关键操作进行了阐述。所提出的对于两种存储策略下BLOB数据的处理方法已成功运用于实际项目开发。
BLOB data such as images, electrical documents, audios and videos can be stored in re- lated databases. By using API provided by ADO. Net and file stream techniques, BLOB data stored in RDBMS can be effectively processed and managed. This paper analyzes the storing strategy of BLOB data in Database and makes a comparison between the two strategies. Finally, the key techniques adopted in BLOB data processing based on ADO. Net are illustrated in detail. The method proposed has been successfully applied to the development of specific projects in practice.
