2. SCAM 2007 Paris 1/10/2007 Goals&Means Demo Toolset 2/8 Case study Case Study: ‘Rekenmachine’ An information system of a large insurance company: A middle layer COBOL application MicroFocus 4.1 COBOL runtime Maestro II development environment (2827 COBOL modules, ~1700 KLOCs) supports both online requests and batch execution AIX 4.3 operating system Oracle8i database: 800 tables,30 GB

3. SCAM 2007 Paris 1/10/2007 Goals&Means Demo Toolset 3/8 Case study Goals Maintenance: assess quality of the ‘Rekenmachine’ source code in order to identify weak spots Migration: identify the possibilities for code or/and architecture reuse during possible migration to a new platform

4. SCAM 2007 Paris 1/10/2007 Goals&Means Demo Toolset 4/8 Case study Means Quality metrics: system’s maintainability Code duplication detection: restructuring & reuse of code Software structure: restructuring & reuse of architecture

5. SCAM 2007 Paris 1/10/2007 Goals&Means Demo Toolset 5/8 Case study Means Automatically extract software structure and quality metrics and visualize them Parsing and automated fact extraction Visualisation using a set of third-party tools

6. SCAM 2007 Paris 1/10/2007 Goals&Means Demo Toolset 6/8 Case study Toolset A toolset that would: parse source code automatically (~2800 modules, ~1.7 MLOCs) calculate quality metrics and produce inputs for visualisation tools allow the user to reproduce the entire cycle (e.g. after new release) be reusable for other code analysis projects, other languages
