(b) Graphical representation of the XML Schema

With XML, however, such groups can be modeled. The schema shown in Figure 11-53(a)
structures the appropriate columns into an AddressType complexType and other columns
into a PhoneType complexType. A graphical display of this schema is shown in Figure 11-53(b).
An XML document for one of the rows of CUSTOMER expressed in this format is shown in
Figure 11-53(c).
