Model processing tools in UML

Abstract

The Unified Modeling Language (UML) provides several diagram types, viewing a system from different perspectives. In this research, we exploit the logical relationships between different UML models. We propose operations to compare, merge, slice and synthesize UML diagrams based on these relationships. In a formal demonstration, we show how statechart diagrams can be synthesized semi-automatically from a set of sequence diagrams using an interactive algorithm called MAS. We also demonstrate how a class diagram, annotated with pseudocode presentations of key operations, can be synthesized from sequence diagrams, and how class diagrams and sequence diagrams can be sliced against each other.
