Other than the unique key, what data will your record in "meta data"? What does one record in MetaData represent.
"ReceiptInfo" sounds like the data recorded for the purchase or sale of an item or group of items.
But what data will one record in "actual receipt" represent and how does that related to a record or records in ReceiptInfo?
Do you mean that when 4 items are purchased/sold, they will be listed as four items in ReceiptInfo and one record in ActualReceipt?
