第5题：

What are the four basic Data Flow steps of an ETL process?

在ETL过程中四个基本的过程分别是什么？


正确答案：
答：
Kimball数据仓库构建方法中，ETL的过程和传统的实现方法有一些不同，主要分为四个阶段，分别是抽取（extract）、清洗（clean）、一致性处理（comform）和交付（delivery），简称为ECCD。
1．抽取阶段的主要任务是：
读取源系统的数据模型。
连接并访问源系统的数据。
变化数据捕获。
抽取数据到数据准备区。
2．清洗阶段的主要任务是：
清洗并增补列的属性。
清洗并增补数据结构。
清洗并增补数据规则。
增补复杂的业务规则。
建立元数据库描述数据质量。
将清洗后的数据保存到数据准备区。
3．一致性处理阶段的主要任务是：
一致性处理业务标签，即维度表中的描述属性。
一致性处理业务度量及性能指标，通常是事实表中的事实。
去除重复数据。
国际化处理。
将一致性处理后的数据保存到数据准备区。
4．交付阶段的主要任务是：
加载星型的和经过雪花处理的维度表数据。
产生日期维度。
加载退化维度。
加载子维度。
加载1、2、3型的缓慢变化维度。
处理迟到的维度和迟到的事实。
加载多值维度。
加载有复杂层级结构的维度。
加载文本事实到维度表。
处理事实表的代理键。
加载三个基本类型的事实表数据。
加载和更新聚集。
将处理好的数据加载到数据仓库。
从这个任务列表中可以看出，ETL的过程和数据仓库建模的过程结合的非常紧密。换句话说，ETL系统的设计应该和目标表的设计同时开始。通常来说，数据仓库架构师和ETL系统设计师是同一个人。

(4 marks)


正确答案：
(e) In order to enhance profitability management might take the following actions:
(i) Increase the maximum capacity of the circus.
(ii) Undertake a detailed review of operating costs which are budgeted at ￡239,200,000. Such a review might identify nonvalue
added costs which may be eliminated thereby increasing profitability.
(iii) Enter into a strategic arrangement with large hotels and travel agencies to offer travel and accommodation inclusive
arrangements for visitors to Cinola Island. This might help to increase the number of visitors to the zoo thereby increasing
profits.
(iv) Change the price structure and entitlement of tickets so that purchasers might visit Cinola Island on two separate days
in order to attend the zoo and circus. Additional revenues would arise as a consequence of the increased number of
visitors to the zoo, thereby increasing profitability.
(v) Hold prize draws for free tickets to the zoo for families on an ‘all-inclusive basis’, including restaurants, photographs,
souvenirs etc.
N.B. Only four initiatives were required to be discussed.
