Model Explorer Model View

The Model view displays from the Model tab in the Model Explorer. The Model view displays every object that exists in the model excluding descriptions, definitions, notes, user-defined properties, rolenames, referential integrity actions, and annotations. The objects are arranged roughly by their ownership hierarchy, and a root node representing the model is displayed in the tree. The model's Name property is used to display the name of the model in the tree. The architecture specifies that all objects can have names and assigns a default name if you do not provide one.

The primary purpose of the Model view is model exploration and to serve as an alternative to the diagram as a launching point for editors.

For example, you can define logical or physical domains in the Domain Editor. You can drag any domain from the Model Explorer to an entity, table, or view in the diagram window to create an attribute or column, which inherits its properties from the domain from which it was created.

You can sort domains in hierarchical or alphabetical order to easily find the domain you want to assign, modify, or review.

Many objects will not be visible in this view due to one of three reasons:

• The object is not visible in the current display mode of the diagram window. An example is a when a View is not visible when the diagram window is in Logical display mode.
• The object is a minor object that is completely handled by the editors of its parent object, such as a Valid Value object. They are created, destroyed, and edited by the Validation Rule editors.
• The object represents configuration information stored by a process and not actual model data, such as a Complete Compare Option Set.
