MDRE

Model Driven Reverse Engineering

Introduction

Reverse Engineering is the process of examining an already implemented software system to represent it in a different form/formalism and at a higher abstraction level

State-of-the-Art

MDRE vs. Reverse Engineering (early 2000’s)
  • Analysis platforms, language workbenches

  • OMG’s Architecture Driven Modernization

Specific MDRE solutions
  • Programming languages (Java, C++)

  • Goals: migration, integration, analysis

General-purpose MDRE solutions
  • Some general modeling (commercial) tools

  • Few generic MDRE solutions…​

Challenges

  • Are we able to deploy our approach on practical scenarios / systems of various technical natures?

  • Are we able to adapt and reuse our approach / components as part of other (MDRE) solutions?

  • Are we able to use our approach in the context of large-scale scenarios / systems?

Conceptual Approach (1/3)

  1. MDRE framework architecture

    • Reuse and integration examples

    • Technology-specific components

    • Technology-independent bricks
