================================
都说BI，什么OLAP，什么ROLAP,MOLAP，但是如何基于RDBMS实现，基本都不怎么说。
怎么做的：
1.通过多维分析模型，存储元数据
2.动态建立主题临时表
3.依据多维模型的元数据，组装SQL，创建临时表，插入数据到临时表
================================
程序使用SQL都是针对Select，Update，Delete
但是很少用create table，drop table，其实在数据库分析中，就是这种场景
数据库原始视图在开发中的使用....,场景也有，比如查看表已经表的主外键
================================
生成的临时表结构--本质还是对这个临时表的理解个人感觉
DIM_*:这些就是维度
DIM_*_DATA:就是具体的度量值或者指标
这个表是根据用户的多维分析的模型和用户自定义的表格有关，他会自动生成。
查询语句：
SELECT DIM_27_CODE AS DIM_27_CODE,
MAX(DIM_27_DISPLAY) AS DIM_27_DISPLAY,
DIM_29_CODE AS DIM_29_CODE,
MAX(DIM_29_DISPLAY) AS DIM_29_DISPLAY,
DIM_DATE_CODE AS DIM_DATE_LAST_CODE,
SUM(DIM_95_DATA) AS DIM_95_DATA

BI的需求说白了，就是可以按需要出一些报表（客户处存在专门的业务分析人员），这就是BI的需求。
但是对于我们开发来说如何实现？？？？？？
理论上，现在都存在一些多维分析模型，这是一种理论化的解决方案，在开发中，编码实现对多维模型进行分析进而形成元数据metedata，最为关键的。其次就是数据的存储。
上面的SQL本质就是根据多维模型的元数据进而形成SQL（以前我们面向SQL开发报表），进而抽取数据存到临时表，也算是一种数据的物化吧.
