4. INTRODUCTION TO PATTERNS
Patterns was
conceived to
develop software
simple and
predictable.

10. Why select Undo/Redo?
Undo/Redo has relationship with Feedback and Cancel

11. FEW DEFINITION
What is the definition of Undo and Redo?
Service Oriented Architecture for Undo Functionality 11

12. UNDO CHARACTERISTICS
In most case updates are atomic
Undo/Redo consist in reinjection of input
This strategy is not valid to word processor

16. OUR FRAMEWORK
Service Oriented Architecture for Undo Functionality 16

17. FRAMEWORK Advantage
Knowledge of Undo/Redo is
confined to Framework.
Data inputs can be
processed automatically.
It avoids the complexity of
in-memory objects.

18. Frameworks = Iceberg

19. Rethink the Framework

21. Software as a Service (SaaS)
21

22. SaaS Advantage
Scalable.

27. CONCLUSIONS I
Easy to Add.

28. CONCLUSIONS II
Support different applications.
