Transforms in the Model Explorer

Each transform that you apply to model objects appears in the Model pane in the Model Explorer. By default, each transform is listed in alphabetical order under the Transforms folder.

You can right-click a transform in the Model Explorer and choose Properties to open the Modify Properties for Transform dialog for the selected Transform. You can use the Modify Transform Properties dialog to document the reason that you applied a transform, assign user-defined properties to a transform, and specify that any future changes that you make to the transformed object (such as adding attributes, columns, or relationships) are also applied to the source objects.

You can also rename or delete a transform.

You can apply the following transforms to model objects to refine a logical or physical model:

Many-to-many Transform

Resolves a many-to-many relationship

Vertical Partition

Vertically partitions a table

Horizontal Partition

Horizontally partitions a table

Roll-Down denormalization

Supertype-Subtype Identity

Supertype-Subtype Rollup

Rolls up all primary key and non-key attributes in the subtype entities to the supertype entity

Supertype-Subtype Rolldown

Rolls down all primary key and non-key attributes in a supertype entity to the subtype entities

Column denormalization

Copies a column from one table to another, and then link the two columns (column denormalization)
