This is accomplished through to use of cookies, CGI forms, a customer database, and data mining analyses. It also involves using the preference information provided by the visitors as they register or make their purchases, and sending targeted reminders via e-mail or providing them special lists of services or products on their return to your site. Data mining is the missing link in providing the connection and relationship between consumers and the Web—a relationship that can be leveraged to serve them in a timely, efficient, and personal manner.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{9AB}'/><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>Although some consumers are concerned about privacy and security, many continue to register at websites and fill out surveys and sign up for one-click credit card ordering. The fact is that personal information is more secure online than offline. Consider how many people look at your credit card number when it is taken away by a waiter you have never seen before. In addition, personal preferences of products are already routinely captured every time you use your credit card—to the level that these companies know whether you use room service or not. Supermarket retailers, who encourage you to use their discount cards, already know the number of apples you consume in a week.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{9AC}'/><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>Customer preference information about what you like and consume is already out there and is being used to position the right products, services, and messages in front of you. Convenience drives the sales on the Web for individuals who on the average have higher-than-average incomes and education levels and tend to be very busy. On the whole, more and more consumers will come to accept that by providing some personal information, services will improve and products will be better suited to their unique needs. By providing personal preferences, consumers will find that the "right" products, services, and information will flow to them, rather than their having to go out and search for them in the ever-expanding Web.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{9AD}'/><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>To demonstrate how data mining can be used to improve online sales, an analysis was performed on a small sample of visitors who had made purchases of computer hardware. The objective is to discover what attributes constitute good prospects for this website. We begin the analysis by selecting our desired output, in this case "total number of sales" (Figure 8-12).</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{9AE}'/><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>The total number of customer account records for the analysis was 1200, and the total number of errors was 66.
