However, this verification type of data mining is limited in several ways. First, it is based on a hunch—that there is a relationship between the industry a company is in and the number of printers it buys or leases. Second, the quality of the extracted information is based on the user's interpretation of the results and is thus subject to error.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{1F9}'/><TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0><TR> <TD ROWSPAN=5></TD> <TD COLSPAN=3 HEIGHT=12></TD> <TD ROWSPAN=5></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR><TD></TD> <TD><FONT FACE='Times New Roman, Times, Serif' SIZE=3>In another example, an OLAP tool can tell a bookseller about the total number of books it sold for a region during a quarter.
