Subject: 所有的Cube都是事先设计好的么?
小弟想问一个问题,是不是所有的Cube都是在设计事情事先规划、构建好的?有没有可以在运行时期根据用户数据特点自动构建的Cube呢?如果有的话,
哪个公司的产品有这种功能?
谢谢了。

咦,你这个想法好嗳,不过没听过这样的产品,不知道其他人有没有听过或见过。

但我想你说的根据用户数据特点自动构建有点问题,cube毕竟还是要从分析需求出发的吧,以前看过很多cube的维度都是跟数据库的码表一致,但那些描述跟业务 术语、分类都有些细微区别,虽然只是一点点小小差别,但非常影响cube的使用。所以,不知道有没有这种根据业务人员的分析需求,可以自动构建cube的产品呢 ?

恩,可能根据纯粹的关系型数据来动态构建Cube有些困难。我想因为关系型数据库本身表示的元数据有限,你说的那些业务术语词汇不一定能够存储。但是
XML就有可能了。这段时间在做一个prototype,其中包含了两个点,一是从XML构建Cube,另外一个是根据XML的结构动态构建Cube。
思路应该还可以,但是说到性能.....算了,这阶段还没到考虑性能的时候。
所以有此一问,想看看市面上的东西有没有可以参考的。

窃以为多维数据库有点你说的动态的意思
起码多维数据库都支持XMLa

其实说白了就是要解决多维分析的够灵活,够快速,够多存数据,三够都要满足。

动态构建,类似于Dependency Injection概念?大多依赖于XML

自动构建是啥意思?维度与度量是自动由系统选择出来的?

我感觉由business user能够自主来选择就够了吧。如果是这个意思的话,即席查询(Ad-hoc Query)是不是就能搞定?
