What is a model?

A model is an abstraction of a system. RUP method: A complete description of a system from

a particular perspective. Examples of models:

UML model Code Data model

Models at different levels

Platform-Independent Model (PIM)

Code-based Development

ITER

ATE

Application design (high abstraction)

Implementation

Application use cases

Application analysis

ComputationalIndependent Model (CIM)

Platform-Specific Model

(PSM)

Business analysisBusiness process models

Business use cases

Model-Driven Architecture

(MDA)RUP method

Platform-specific model markup

UML and implementation projects

Project types for UML and text-based (code) models: UML projects:

For pre-implementation models Blank or based on a model template

Implementation projects: Java, EJB (Enterprise JavaBeans)

technology, and so on Implementation projects can contain

UML Models Use models to:

Specify structure, behavior, or both Visualize an existing system to improve understanding Automate system development (Model-Driven Development)

UML model files (.emx) contain: Model elements Diagrams Profile information User preferences Workspace information

Navigator viewshows physical model files.

Project Explorer shows models, diagrams, and model elements.

Developing multiple models

You can model a system using multiple models

How many models to use depends on: The modeled system and

model complexity Team development and

configuration management considerations

Organizational standards and practices

Your own preference

Creating a model from an existing model

Base new models on existing models Use an existing model as

a template Provides an

organization-specific starting point for modeling Associate custom profiles Create your own

standard model structure Reuse existing solutions

Example Building Block element

Populate a model with reusable building blocks

Create a UML project and select a template. Then populate the model with: UML packages UML elements based on model

building blocks provided Simplified and blank template

versions are available

Use Case Model

A use-case model is a model of the systems intended functions, and of its environment.

CT015-3.5-2 Design Methods UML Model

Analysis Model

An analysis model describes the realization of use cases to analysis classes.

Provides an abstraction of the design model

Service Design Model

A Service Design Model is used in the development of service-oriented architectures

CT015-3.5-2 Design Methods UML Model

Web publishing models

The publishing process re-creates model elements, including diagrams, relationships, and attributes.

What are the forms that a model can take?

What model templates are available?

What are model building blocks and why would you use them?
