UML Model

A UML model is a collection of UML elements, diagrams,and data such as relationships and requirementsinformation, that describe a real-world system.A software architect uses UML to build models that describe the quantifiable characteristics of a system such as the:

System's structure Behaviour Constraints Dependencies

INF 2120

Model elements

The building blocks of a UML model are called model elements.Model elements are the data representation of a real world object, actor, or system.


INF 2120

Diagram elements

A UML diagram contains diagram elements (sometimes called shapes)They visually describe the classifiers in a diagramThese classifiers are the diagrammatic representation of a model elementDiagram elements are not considered part of the semantic model


INF 2120

Diagrams

A UML diagram describes the quantifiable aspects of a system that can be visually describedSuch as: Relationships, behavior, structure, and functionalityFor example, a use case diagram describes the interactions between the users of the system, called the actors, and the system

Rational Modeller / Architect


INF 2120

IBM Rational® Software Architect

Provides a flexible development environment for creating and editing UML models. You can use the Model Explorer view to edit the source code and model structure of the semantic model. You can use the diagram editor to edit the visualized model. When you edit models, you should understand the differencesbetween model elements and diagram elements. For example, when you right-click an element in the diagram editor, there are two delete options. If you click Delete from Diagram, the element is deleted from the diagram only, because the diagram element is only a visualization of a model element. Conversely, if you click Delete from Model, the element is deleted from both the model and the diagram.

Create a new project

From File menuchoose :

1.New

2.Project

3.Modeling

4.UML Project


INF 2120

Model Editor


INF 2120

Creating a new class diagram

1. Right-click your model

2. Add Diagram

3. Class Diagram


INF 2120

Adding a class to your model (1)

Classes can be added

from the Model

explorer field:

1. Right click your new class model

2. Add UML

3. Class


INF 2120

Adding a class to your model (2)

From the Palette

on the right side of

your screen:

1. Left-click the class icon

2. Left-click or click and drag in the editor

3. Enter the name of the class


INF 2120

Adding a class to your model (3)Or simply holdthe mouse still in the editor:1. A menu will

appear2. Choose what

element you want to create

3. Enter element name


INF 2120

Adding attributes and operations to your classAttributes and operations can be added in different ways:1. By holding the

pointer over the class element for some seconds

2. Right-clicking the class in the Model Explorer view

3. Right-clicking the class element in the diagram


INF 2120

The Property view

Every element in a diagram has propertiesA class can be public, protected or privateAssociations have multiplicity, roles, types…A diagram has name and a type: DomainACSys <> classWe have the property tab / viewLet’s look at the association property view


INF 2120

Association property view

1. Click once at the association between two classes

2. Choose the property tab

3. Here we can change the roles, label and the multiplicity of an association


INF 2120

Composite Structure

Right-click class in Model ExplorerAdd diagramComposite structure diagramThe classes from the class diagram is now included (if any composition)Hold mouse on diagram element to create port or connector, (as shown)


INF 2120

Sequence Diagram

Create a new UML diagram the same way you created the class and the composite diagram. This is the palette that will appear. You can now drag and drop classes from the Model Explorer or create new classes


INF 2120

Sequence Diagrams Palette

Some alternatives have a drop-down arrow. Click this for different messages or combined frag-ments


INF 2120

Alternative Combined Fragments

Click on Option combined fragment arrowChoose altWhich operand decided by “[ ]”


INF 2120

Adding an operand

Right-click alt boxChoose Interaction OperandAdd before or after inserts a new alt

The world is NOT perfect

Rational Software Development Platform is a new toolØystein Haugen was a beta test-user and reported lots of errors and weaknessesSome of the errors are not yet fixedThis includes attaching messages to the frame in Sequence DiagramsDecomposition of lifelines (placing the Ref: ). One solution to this is just placing the ref in front of the object name in /**Ref: sd MakePayment**/ or attaching a noteContinuations not implemented.Execution occurrences appears automatically even when asynchronous messages are used. Annoying but just delete it from the model.


INF 2120

Example on how to fix shortcomings

Lifeline decompositionCreate an unspecified lifeline with no namePlace it on the side and connect the message “out of frame” to itContinuation


INF 2120

Smart things to remember

Window, Reset perspective: The workbench returns to its default view.Fast view. Drag the view to the right bottom of the screen. Then you can look at it with a simple click. When you click somewhere outside the view, it closes.Restore a fast view by dragging it back into the workbench.Double-clicking a tab maximises the view, again back to normal Help menu wasn’t made just for fun!Tutorials and samples: A good place to start!
