BW APD简述
APD：Analysis Process Designer(事务代码：RSANWB)：分析处理设计器
简单的讲：APD的目的是把相关的计算结果再次进行关联、存储、分析使用，以便进行更为复杂的、精确的分析，专业点讲就是数据挖掘什么的
SAP帮助的说法是：
In SAP BW, data from various databases from systems available in the company are collected, consolidated, managed and prepared for evaluation purposes. There is often further, valuable potential in this data.It deals with completely new information that is displayed in the form of meaningful connectivity between data but that is too well hidden or complex to be discovered by simple observation or intuition.The Analysis Process Designer (APD) makes it possible to find and identify these hidden or complex relationships between data in a simple way. Various data transformations are provided for this purpose, such as statistical and mathematical calculations, and data cleansing or structuring processes.
The analysis results are saved in BW data targets or in a CRM system. They are available for all decision and application processes and thus can be decisive (strategically, tactically, operatively).
个人觉得比较有用的是把Query结果存储到ODS中，这个ODS是传统的ODS，即3.5版本的，7.0中都叫DSO了，貌似不可使用，这个BW的升级还是不够彻底呀。
