I's like to ask about etl, and fact table.
Likely, my fact table's structure is like this :
Id | Name | QuestionAanswer | QuestionBanswer | QuestionCanswer
I have dimension like this :
QuestionStaging data came from csv files, which the name is structurely randomed like A257_IDr, H1_ques1, H2_ques2, H3_ques3. ex :
A001 | 1 | 2 | 1 |
where A001
-> UserID and 1,2,1
-> User's answer to following question.
QuestionDimension's structure is like:
SK_Question | ID_Question | IDAnswer
ex. I have the following question like =
How are yours company profit this year? Bad:Good:Best
then the data's structure in table is like :
Sk_Question | IDQuestion | IdAnswer | AnswerDetail
1 Q1 1 Bad
2 Q1 1 Good
3 Q2 1 Best
My Expectation FactTable is likely to :
SK_USer |Id | Name | QuestionAanswer | QuestionBanswer | QuestionCanswer
1 A001 Richard 1 1 2
OR
1 A001 Richard Bad Bad Good
What data flow component or control flow should I used for these situation?
您将需要一个平面文件连接管理器,数据流控制组件,平面文件数据源任务以及一个数据目标任务(可能是OLE DB),具体取决于您的数据库。
