Go Up to Conceptual Model Elements
Conceptual Modeling allows Business Users to create high-level designs of the core “concepts” and subject areas that drive the business, which can be passed onto data and process modelers to drive more detailed logical and physical design. A Subject Area can reference a collection of entities. You can embed the entities in the Subject Area, or you can have the Subject Area reference a diagram with multiple entities.
- A Subject Area can be Create Mapping/Edit Mapping to other Conceptual Model diagrams.
- The Subject Area presentation element in the Diagram View can be shown as an oval or a rectangle. You can set this as a global preference. You can also set the shape for each individual Subject Area in its Property View. Double-click on a Subject Area, select the Appearance tab in the Property View and then make your selection under the Shape option.
- Subject Areas can be expanded or collapsed. You can then view or hide Business Entities or other Subject Areas within the parent Subject Area. Right-click in a Subject Area in the Diagram View and select Show as Expanded. This is a toggle command.
- You can also elect to hide or show the expansion control in the Subject Area in the Diagram View. Right-click the Subject Area and select Show Expansion Control. Depending on the state of the element (expanded or contracted), a plus or minus symbol is placed in the bottom center of the Subject Area. This is a toggle command. You can also choose to show or hide the expansion control as a global preference.
- When a Subject Area is placed in the Diagram View, the label appears vertically centered. Once you add a child element the label is then relocated to the top center of the Subject Area.
- Once other Subject Areas have been placed within a Subject Area, these child items appear on the Impact Analysis tab under the “Heritage” () heading. You can view this Impact Analysis Report in the Property View for the Subject Area.
- Note: When a Business Entity is placed within a Subject Area, this is a mapping action and appears under the Mappings () heading in the Impact Analysis Report.
- The following example shows a simple, expanded Subject Area with three Business Entities. Business Entities contain Business Attributes which are properties of that entity.
