Hi,
I am new with the ETL development. We have excel as our sources and my boss wants get them into SQl. Now we need to write packages for loading data. But he says that there has to be a Common Interface Format Layout (CIF) which acts as a middle layer between the Source and the Destination. He says on his experience(which he has used yrs back) that a source is mapped to the CIF and all loading following the CIF will occur without modifications . in a docuement we got at work says CIF means when a measure us recieved , the source is mapped to the CIF and all loading following the CIF will occur without modifications
If So How do we develop this CIF.
Thanks in advance
