The Transformations Toolbar

The Transformations toolbar provides a set of tools to apply transformations. The model type and the objects that you want to participate in the transformation determine the tools that are available on this toolbar.

Transformations Toolbar

Supported transformations include:

Many to Many transformation icon Resolve Many-to-Many Relationship

Supertype Subtype Identity transformation icon Resolve to Supertype-Subtype Identity

Supertype Subtype Rollup transformation icon Supertype-Subtype RollUp

Supertype Subtype Rolldown transformation icon Supertype-Subtype RollDown

Vertical Partition transformation icon Vertical Partition

Horizontal Partition transformation icon Horizontal Partition

Two Table Roll Down toolbar icon Two Table RollDown

Two Table Roll Up transformation icon Two Table RollUp

Resolve All Transformations icon Resolve All Transformations

Resolving all transformations triggers a process for all supertypes/subtypes and many-to-many relationships. Many-to-many relationships are removed and for supertypes/subtypes it replaces all subtype relationships with identifying relationships.

To display or hide the Transformations toolbar, click Toolbars, Transformations on the View menu.
