| 摘 要： | 针对复杂生态信息的存储与管理问题,提出一种基于B 树的多维层次聚集立方体存储结构模型。通过将d维数据空间构建成多维层次式B 树,并节点进行压缩的二进制维层次编码,在此基础上实现了模型的快速查询、数据更新与模式更新算法。与传统的Data Cube相比,MH-Cube具有较好的查询与更新功能。生态数值实验表明,模型可为复杂生态信息的存储与管理提供较好的解决方案。

| Abstract: | For the problems of the storage and management of complex ecological information,a multi-dimensional hierarchical aggregation cube(MH-Cube) model based on B tree was proposed.A multi-dimensional hierarchical B tree was set up from a d dimension space with binary codes to realize quick query,data update and pattern update algorithms.Compared to the conventional cubes,MH-Cube exhibited better performance.The ecological data experiments showed that the model provided a good solution to the problems of the storage and management of complex ecological information. |
