Assume that there could be any number of product keys and for each product key the sales figures (denoted by 'x' are stored for each of the 12 months from Jan to Dec). So we want the result in the target table in the following form. Product_id Jan Feb March.. Dec 1 x x x x 2 x x x x 3 x x x x . . So how will you design the ETL mapping for this case , explain in temrs of transformations.
