	One of the most popular applications of the concept of Graphics in ROB is the inclusion 
	 of Diagrams in ROB reports. Diagrams, such as Entity Relationship Diagrams {entity_relationship_diagrammer.gif, ALT="Entity relationship diagrammer"}
	 (ERD) or Data Diagram {data_diagram.gif, ALT="Data diagram"} (DD) present an often accessible overview
	 of a large collection of related objects such as Entities or Table Definitions.
	 Showing these diagrams on the Web brings this overview to the end users that do
	 not necessarily go into the Oracle Designer toolset themselves. It also provides
	 quick and easy access through simple browsing to diagrams to analysts and developers.<BR><BR><b>Hotspots
	 and Clickable Diagrams</b>Even more value is added to the concept of diagrams as
	 Graphics when they can be used as portal to reports for the objects shown on the
	 diagram. Making the diagram <i>clickable</i> means: enabling the end user to click
	 on objects shown on the diagram, thereby providing a hyperlink/navigation short
	 cut to the report for the clicked-on object. For example: if we make an entity relationship
	 diagram clickable, it means that an ROB user can click on the entities displayed
	 in the diagram and jump to the associated entity report. As a bonus, clickable objects
	 on diagram will show a balloon help text with the full name of the object. Refer
	 to the related help text below this subject <BR><BR>Unfortunately, diagrams that are shown in ROB are
	 not dynamically extracted from the Oracle Designer tables. ROB can only show images
	 of diagrams. And you have to create such images yourself. Note that is also means
	 that if you change the diagram in Oracle Designer after you have created the image
	 of the diagram, the image and the real diagram are no longer in synch. This probably
	 means that for diagrams that undergo many changes you have to periodically create
	 fresh images.<BR>
