  1. A Generic And Extensible Framework For Model Driven Reverse Engineering ModiscO

  2. 1. Why => Reverse Engineering? Up-to-date data Manage functionalities Maintain Replace architecture

  3. 1. Out-of-date systems are still running: • Complexity and heterogeneous • Size • Migration cost • 2. Quickly reengineering existing system. 1. WHY => Reverse Engineering?

  4. A tradition of using UML Modisco Principles and Techniques *.java Structure diagrams ? Behavior diagrams

  5. Some UML reverse engineering tools Modisco Principles and Techniques *.class *.java Fujaba Topcased

  6. MoDisco: Models is the first class entities of all processes => reverse engineering Modisco Principles and Techniques homogeneous heterogeneous M Model Driven Reverse Engineering (MDRE) S M’ M’’ Model understanding Model discovery

  7. Model Discovery Model Discovery jsp java struts xml Spring Hibernate database Natural -> Type of system Several models necessary Metamodel

  8. Model Understanding Source code document Structured data Many models transformation -> be used Several intermediate representation -> necessary

  9. Discovery, query and manipulation Modisco – THE Whole Picture

  10. Modisco – Architecture

  11. MoDisco User-Cases Modisco – Architecture

  12. MoDisco Technologies Modisco – Architecture

  13. Reverse Engineering - Control Dependence graph

  14. Reverse Engineering - Control Dependence graph public List<PizzaOrder> getDailyReport() throws ServiceException { try { dbDAO.startTransaction(); List<PizzaOrder> orders = getTodaysOrders(); // materialize details during tx for (PizzaOrder o: orders) { o.getPizzaSize().getSizeName(); for (Topping t: o.getToppings()) t.getToppingName(); } dbDAO.commitTransaction(); return orders; } catch (Exception e) { dbDAO.rollbackAfterException(); throw new ServiceException("Error while getting daily report ", e); } }
