zz:Silo effect

1. 在 Maven "History" 网页上看到 Patterns for Evolving Frameworks http://st-www.cs.illinois.edu/users/droberts/evolve.html

从 concrete 的地方出发,更容易做成有用的东西。

2. 在 Maven "Philosophy" 网页上看到 silo effect http://en.wikipedia.org/wiki/Information_silo#Silo_effect

Wiki 不知道怎么又说到供应链管理,然后提到 Bullwhip effect http://en.wikipedia.org/wiki/Bullwhip_effect

3. 在 "silo effect" 的介绍中,又提到 ETL http://en.wikipedia.org/wiki/Extract,_Transform,_Load

这个正是 DataPotluck#6,Xiaohong 的演示文稿里用的词。

The typical real-life ETL cycle consists of the following execution steps:

  1. Cycle initiation
  2. Build reference data
  3. Extract (from sources)
  4. Validate
  5. Transform (clean, apply business rules, check for data integrity, create aggregates or disaggregates)
  6. Stage (load into staging tables, if used)
  7. Audit reports (for example, on compliance with business rules. Also, in case of failure, helps to diagnose/repair)
  8. Publish (to target tables)
  9. Archive
  10. Clean up


* 从工作的角度看,公司的流程既然如此相似,是不是利用了整个行业的特点?
* 从OpenGovernment的角度看,这些人做的有多少是无用功,怎么从 Data Integration http://en.wikipedia.org/wiki/Data_Integration 的角度想问题?
* 我自己的工作中,有多少设计是可以给外部用户提供一致的接口的?怎么做 Data Integration design?
* 为什么这些流程上的东西,会被研究得这么细致?一件事情,一种特征,出现那么多文章、那么多名词、示例来分析他。
* Maven 和 autotools 是什么关系? disclaimer: I know too few about either, or anything above.
