AR-10 Change Shared Kernel to Partnership

This simple relationship refactoring changes a Shared Kernel relationship on a Context Map to a Partnership relationship.

Summary

Our relationship refactorings allow the user/modeller to change the type of a relationship on a Context Map easily without manual work. The symmetric relationships according to our semantic model, Shared Kernel and Partnership, are interchangeable without impacts to the structure of the decomposition. This refactoring changes a Shared Kernel relationship to a Partnership relationship.

Example

The following two CML snippets show an example input and output illustrating how this AR works.

Input

The input Context Map:

ContextMap InsuranceContextMap {
  type = SYSTEM_LANDSCAPE
  state = TO_BE
  contains PolicyManagementContext
  contains DebtCollection

  /* With a right-click on the Shared Kernel relationship ([SK]<->[SK]) you can execute the 'Change to Partnership' 
   * refactoring. It will replace the Shared Kernel relationship below with a corresponding Partnership relationship
   * between the two Bounded Contexts.
   */
  PolicyManagementContext [SK]<->[SK] DebtCollection

}

BoundedContext PolicyManagementContext

BoundedContext DebtCollection

Output

Applying the AR Change Shared Kernel to Partnership replaces the existing Shared Kernel relationship with a Partnership relationship:

ContextMap InsuranceContextMap {
  type = SYSTEM_LANDSCAPE
  state = TO_BE
  contains PolicyManagementContext
  contains DebtCollection

  /* The new Partnership relationship after applying the 'Change Shared Kernel to Partnership' refactoring to the 
   * Shared Kernel within the 'example-input.cml' file:
   */
  PolicyManagementContext [P] <-> [P] DebtCollection

}

BoundedContext PolicyManagementContext

BoundedContext DebtCollection
