Transformations

Transformations create elements in a target model (domain) based on elements from a source model Often, the source domain is more

abstract than the target domain Examples:

Based on a use-case model, create an analysis model that realizes the use cases following a modeling standard

Based on the analysis model, create a design model that incorporates elements of the companys security and persistence frameworks, and follows a modeling standard

Starting with a UML model, apply a built-in transformation to create code elements

Take existing code and apply a transformation to abstract out the design elements. Transformations

Reverse Transformations

Java and C++ transformations can be reversed Enable a reverse transformation in the

transformation configuration Allows you to synchronize changes between UML

models and C++ and Java code If necessary, compare and merge session starts when

transformation is run

UML Visual Development

C++ and Java code can be visualized with class and sequence diagrams Changes to the code update the diagram Changes to the diagram update the code Harvest classes into UML models
