1.In a project source systems are differnet and also all
source systems are not availble in same time.for eg 1
source is availble at 1AM and 2n one at 2 AM etc
But our schedule jobs run at different time ,so we have to
pick the data from source system based on source availble
time and put into staging area.
2.All source systems table formats and column formats are
diffrent ,so we have to sync all .
For above two reasons we go for staging area
