Which approach is considered most effective when supporting multi-dimensional business report requests?下面哪一个方法是对多维业务分析报告最有效的?:()?
(A)OLAP分析型数据处理(On-Line Analytic Processing)
(B)ODS贴源层(Operational Data Store)
(C)BI商业智能(即BI报表,Business Intelligence)
(D)OLTP事务型数据处理(On-Line Transaction Processing)
(E)EDI电子数据交换(Electronic Data Interchange) 答案解析: EDI:EDI是数据交换的方法,不是数据分析的技术ODS:ODS是贴源层,数据建模分层的第一层,也与题目无关BI:通常指报表展示平台,不是分析技术OLTP:这是指应用系统数据处理技术,属事务型技术,如平时见到的商城、ERP、OMS等,如增删改查一个商品或订单等的,这种叫OLTPOLAP:OLAP通常指数仓大规模的数据分析,无论是多少维,只要是出报表,就是用到OLAP技术,如HADOOP的MR、SPARK等,均是OLAP技术
