The Subject Area tab in the Model Explorer displays all the objects available in the selected Subject Area. The Subject Area view provides a filtered view of the model to minimize unnecessary tree information that is encountered when working with large models. The Subject Area view displays model objects sorted by subject area excluding drawing objects, descriptions, definitions, notes, user-defined properties, rolenames, referential integrity actions, and annotations. You can see the drawing objects in the subject area view, under Diagrams, Shapes. You can expand each subject area to see a list of the objects that reside in the subject area including any diagrams. Diagrams appear in a node below the subject area that they are linked to in the Model Explorer.
You can select a subject area in the drop-down box located at the top of the Model Explorer Subject Area view. The contents of the selected subject area are filtered to include only those objects that are contained within this subject area or that are global. You can see tables categorized as tables, and views categorized as views, unlike what is displayed under subject area nodes in the Model view. Relationships are filtered to show only those visible on the diagram (relationships are visible on the diagram when both endpoints are present in the subject area). Global nodes that do not relate to working within a subject area, such as subject area nodes and model source nodes, are not displayed.
You can move model objects, including entities, tables, and views, from the Subject Area view to a different subject area on the diagram window. For example, in the Subject Area view, you can select the Employee entity in the Accounting subject area and then move it to the Human Resources subject area by dragging it to the diagram window.
