The first five columns of the table use traditional SQL data types and track the information on the product sold, including its identification number, the manufacturer, the name of the goods, the storage unit (stock-keeping unit, SKU) and the proposed retail price (suggested retail price, SRP). The "comments " table contains XML data containing information on goods received from buyers.

Please note that the internal structure of XML-data is not specified when the XML table is established. It's defined by design itself. XML documents describe themselves and their internal structure can be very diverse. The only requirement that DB2 is to keep XML is that the data are " correctly formed " , i.e. conforming to the certain syntax rules set out in " W3C standard for XML " .
