摘要
根据SAN(storage area network)存储模式的分块理论,以64M作为block分块单位,设计了分块算法的实现.重点研究了使用底层的SQL Server开发工具对数据库资源平台的元数据进行库结构调整.利用apabi元数据的标识找到了与此元数据相对应的SQL表.修改元数据就是对SQL的表进行操作.最后,使用XML语言设计出了形象直观的农业学科书评数据库的元数据信息.
Based on the theory of SAN storage mode of block, with 64 M as block unit, the partitioning algorithm is designed. Meanwhile, using basic development tool of SQL Server, an adjustment to metadata of Apabi on library structure is researched and probed. By using apabi metadata identification, the corresponding SQL tables are found. Modifying the metadata is to modify the SQL table. At last, the metadata information of agricultural subject review database is designed by using XML language.
