Abstract:

Data warehouse provides storage and management for mass data, but data schema evolves with time on. When data schema is changed, added or deleted, the data in data warehouse must comply with the changed data schema, so data warehouse must be re-organized or re-constructed, but this process is exhausting and wasteful. In order to cope with these problems, this paper develops an approach to model data cube with XML, which emerges as a universal format for data exchange on the Web and which can make data warehouse flexible and scalable. This paper also extends OLAP algebra for XML based data cube, which is called X-OLAP.

数据仓库为海量数据提供了一种有效的存储管理和查询分析的数据平台, 随着应用需要和万维网的发展应用, 数据仓库中的数据模式会随着时间而发生变化, 需要对数据仓库重组或者重建, 会耗费大量的人力物力.本文提出了基于XML的数据立方数据模型.通过对数据仓库技术、面向对象技术和XML技术的结合的探讨, 提出了基于XML的数据立方以及定义在这种数据模型上的OLAP操作, 从而为基于Web数据仓库的应用提供了一种新的表示和实现方法, 解决了数据仓库中模式演化所带来的重组问题, 保证了数据仓库系统的稳定性、灵活性和可扩
