Generate a BA solution report based on the "Supermarket Case" as following. "A busy supermarket has 5 POS (point-of-sale) terminals, which collect 2,000 customers' data (10,000 transaction records) each day. All the sales records from the POS terminals are transmitted to a centralized server. The transaction records contain the data scanned from barcodes, seller's data inputs and the POS software processed data (discounts, promotions, total sum, etc.) for each customer. The transaction records can be exported as xls/xlsx, txt and csv data formats and stored in the server's backup storage units
