  1. Designing Software Development using UML Diagrams Tyler Hackbarth, Zack Rankin, Andrew Bowman, Jesse Pruitt

  2. Overview • What is a UML diagram? • What kind of UML diagrams • How are some of them implemented? • What is Cacoo? • Demonstration

  3. UML Diagrams • The Unified Modeling Language (UML) is a general-purpose modeling language in the field of software engineering. It provides a set of graphic notation techniques to create visual models of object oriented software-intensive systems. • It was developed by Grady Booch, Ivar Robinson and James Rumbaugh at Rational Software in the 1990s. • UML diagrams covers a very broad spectrum of the software design

  4. Types of UML diagrams • Class Diagram • Component Diagram • Deployment diagram • Object Diagram • Package Diagram • Profile Diagram • Timing Diagram • Composite Diagram • Use case Diagram • Activity Diagram • State Machine Diagram • Sequence Diagram • Communication Diagram • Interaction Diagram

  5. Class Diagrams • The class diagram is the main building block of object orientedmodeling. • It is used both for general conceptual modeling of the systematics of the application, and for detailed modeling translating the models into programming code. • Class diagrams can also be used for data modeling. • The classes in a class diagram represent both the main objects, interactions in the application and the classes to be programmed.

  6. Use Case Diagrams • Comprised of list of steps, • Typically defining interactions between a role (known in Unified Modeling Language (UML) as an “actor”) and a system, to achieve a goal. • The actor can be a human or an external system.

  7. State Machine Diagram • A type of diagram used in computer science and related fields to describe the behavior of systems. • State diagrams require that the system described is composed of a finite number of states. • Sometimes, this is easier described rather than trying to implement

  8. Why Use Diagrams • Presents an easy way to understand how the software implementation is going to be • Especially useful if collaborating with a large amount of software developers or team of developers

  9. Purpose of a UML diagram • UML diagrams are used to communicate between groups of software developers • In particular the diagrams show how the system handles static and dynamic objects over a period of time. • Used at every stage of a systems life cycle starting with specifications all the way to maintenance.

  10. List of Tools • Cacoo (free) • VisualParadigm (free) • MagicDraw (free) • Enterprise architect (free) • UMLet (free) • Visio (Microsoft) • TogetherSoft(professional) • RationalRose (IBM)

  11. Cacoo • Cacoo has a very user friendly interface • No download needed/ Web based • Provides a lot of print options • Can save to a PDF or Jpeg to your computer

  12. Demonstration

  16. CacooMainscreen

  17. For this example we will create a Use Case Diagram. Click Create New Diagram.

  18. After creating a new diagram it should bring up the screen below. Than click on the UML folder

  19. The folder will have a few options to choose from. Select Use case Diagram

  20. Base Template

  21. Modifying Text – Double Click the Text

  22. Adding new Cases

  23. Connecting them

  24. Draw line between the actor and the new Use case

  25. Complete Sample

  26. Summary • UML diagrams present an easy way to show how to go about a software or hardware problem • Very effective use for collaborating with a lot of different resources and people on a project • Cacoo is a fast, free and easy tool to create UML diagrams • A lot of free software to create UML diagrams however most companies have their own UML software
