Examples
- In this section about sei _ olap ' s realization , this paper explains how to design the metadata and how to manage the metadata because the metadata is the kernel of the olap ' s operations , and how to gather the data in the different database system or in the different format , and how to realize these olap ' s standard operations , for examples , slice , dice , drill down , drill up and pivot etc . finally , this paper concludes the advantages and disadvantages of the sei _ olap for which it gives some respects
通过实例阐述如何设计元数据，管理元数据；阐述系统如何在数据采集方面实现了数据源的开放性采集，即对不同数据库系统、不同数据格式的信息进行采集；阐述了如何建立维、指标和主题；阐述了olap中切片、切块、向上钻取、向下钻取、旋转、维指转换运算是如何实现的。最后总结了seiolap工具的缺点和不足，并针对不足之处提出了展望。 - The techniques of establishment and access for multidimensional dataset are discussed . we implement multidimensional query , including drill up / down , slicing etc , and the update of multidimensional data set by the technique of mdx , ado md and dso . the expression of operation by graphic is also implemented
对多维数据集的生成和访问技术作了讨论，通过mdx 、 adomd和dso技术实现了olap多维查询和多维数据集的更新，其中包括浅化、深化、切片等操作，并进一步实现了操作的图形化显示。
