Create a sample XML document that implements the conceptual data model expressed in UML and shown below. Invent 5-10 instances that allow you to demonstrate the structure. Create an appropriate internal DTD. This is a specific set of instances -- you can come up them as you see fit. Be sure to view the XML to ensure it validates. Use  as the name of the "root" element of the XML document.pid,tid, and vid are primary key attributes in each of the entities. You need to add appropriate "links" so that the pages visits are linked to the appropriate page and visitor -- use the patterns to decide on an approach. There are multiple ways to solve this.
