Dynamic Slicing of UML Interaction Overview Diagram

In this paper a novel approach has been proposed for dynamic slicing of UML Interaction Overview Diagram. The proposed technique efficiently deals with the changing or dynamic behavior of the system which is illustrated by UML Interaction Overview Diagram. First, the Interaction Overview Diagram is converted to Interaction Overview Dependency Graph (IODG) by considering all the included sequence diagrams. Next a dynamic slicing algorithm is proposed which traverses the graph for a given slicing rule and creates the slice. The basic working principle of the algorithm is based on marking and unmarking the edges of Interaction Overview Dependency Graph when dependencies between messages emerge and end during execution. Interaction Overview Diagram is beneficial over other UML diagrams as it focuses on the overall interactions carried out in a system. Also, it helps to represent complex scenario in a single diagram. Moreover, use of sequence diagrams as nodes simplifies the process and focuses on sequence of execution for different messages.
