Re: Input Excel to DataWarehouse (Dimension Tables And Fact Table Load)

Come on, this is why some companies order consultants to solve problems. Your question is a bit complex and actually it looks a bit someone other should do the job.
At first I would think about putting the excel content into a database table (say staging). With SQL you can do a lot more complex and helpful things as with processing row by row of an excel file.
Extracting dimensions are greatly supported with SQL distinct expressions. Unpivot data are possible with some User components - search for unpivot in Talend Exchange.
