                                            with duplication is not wasted disk storage. Rather, the problem is data inconsistency. Changes to
                                            customer data made in the Sales and Marketing application may take days or weeks to be made
                                            to the Accounting application’s database. During that period, shipments will reach the customer
                                            without delay, but invoices will be sent to the wrong address. When an organization has inconsis-
                                            tent duplicated data, it is said to have a data integrity problem.
                                               Additionally, when applications are isolated, business processes are disjointed. Suppose a busi-
                                            ness has a rule that credit orders over $15,000 must be preapproved by the Accounts Receivable
                                            department. If the supporting applications are separated, it will be difficult for the two activities to
                                            reconcile their data, and the approval will be slow to grant and possibly erroneous.
                                               In the second row of Figure 7-5, Sales and Marketing wants to approve a $20,000 order with
                                            Ajax. According to the Sales and Marketing database, Ajax has a current balance of $17,800, so
                                            Sales and Marketing requests a total credit amount of $37,800. The Accounting database, however,
                                            shows Ajax with a balance of only $12,300 because the accounts receivable application has cred-
                                            ited Ajax for a return of $5,500. According to Accounting’s records, a total credit authorization of
                                            only $32,300 is needed in order to approve the $20,000 order, so that is all the department grants.
                                               Sales and Marketing doesn’t understand  what  to do  with a credit approval of $32,300.
                                            According to its database, Ajax already owes $17,800, so if the total credit authorization is only
                                            $32,300, did Accounting approve only $14,500 of the new order? And why that amount? Both
                                            departments want to approve the order. It will take numerous emails and phone calls, however, to
                                            sort this out. These interacting business processes are disjointed.
                                               A consequence of such disjointed activities is the lack of integrated enterprise information.
                                            For example, suppose Sales and Marketing wants to know if IndyMac is still a preferred customer.
                                            Assume that determining whether this is so requires a comparison of order history and payment
