Developing Models for Software Design

  • Article

Modeling diagrams help you understand, clarify, and communicate ideas about your code and the user requirements that your software system must support. For example, to describe and communicate user requirements, you can use Unified Modeling Language (UML) use case, activity, class, and sequence diagrams. To describe and communicate the functionality of your system, you can use UML component, class, activity, and sequence diagrams.

Note

To get additional capabilities for this release, download and install the Visual Studio 2010 Microsoft Visual Studio 2010 Visualization and Modeling Feature Pack.

You can create the following UML diagrams in this release:

Customizing Your Model with Profiles and Stereotypes

Customize model elements using stereotypes, to extend the standard UML model elements for specific purposes.

How to: Link from Model Elements to Work Items

Create links between model elements and work items to help you track tasks, test cases, bugs, requirements, issues, or other kinds of work that are associated with specific parts of your model.

How to: Export Images of Diagrams

Save your model and diagrams so that you can share them with other users, including those who do not use Visual Studio Ultimate.

Topic

Task

Visualizing Existing Code

Create dependency graphs, sequence diagrams, and layer diagrams to review and explore unfamiliar code.

Modeling User Requirements

Use models to clarify and communicate the users' needs.

Modeling the Architecture of a Software System

Use models to describe the overall structure and behavior of your system and to make sure that it meets the users' needs.

Validating Your System During Development

Make sure that your software stays consistent with your users' needs and the overall architecture of your system.

Using Models within the Development Process

Use Models in Agile Development

Use models to help you understand and change your system during its development.
