Quick Usage Survey

How many of you…

1. Rigorously use models in development?

2. Use model diagrams to understand?

3. Illustrate key parts of software architecture using models?

4. Never use models?

ModelingWhy Model?

Better understand potential risks prior to building the system

Specify structure or behavior of a system, and communicate it to others

Template for constructing a system, and guiding others in using the system

Document decisions

Collaboration diagrams are commonly used to:Model flows of control by organization

State chart diagrams are commonly used to:Model reactive objects

Activity diagrams are commonly used to:Model a workflow or an operation

Component diagrams are commonly used to:Model source code, executable releases, physical databases, adaptable systems

Deployment diagrams are commonly used to:Model embedded systems, client/server systems, fully distributed systems

Generating CodeThe Basics

Enterprise Architect allows you to:Generate code for specific classes

Generate code as part of a new project Windows® Forms, ASP .NET, Class Library, Web Service, etc.

Generates code in a specific language:C#

C++

Visual Basic .NET

Generate code based on code templates

Generating CodeOperations

Operations can be generated as:Property

Procedure

Event

Constructor or Destructor

Specify location for individual class files that are generated

Preview pane to view the code that will be generated

Code Templates for Classes, Attributes, Operations, etc.

Generating CodeError Checking

UML Diagram are also checked for two types of errors:

Semantic

Code

Semantic errors include missing and incomplete information related to the diagram

Code errors include errors that could prevent generated code from compiling successfully

Generating ReportsBasics

UML | Reports menu

Allows you to generate a wide variety of reports

Static Structure

State Chart

Component

Deployment

Activity

Report presentation is customizable

Generating ReportsReport Contents

You can limit the scope of the reportBase the report on:

Active diagramEntire UML Model

Specify object categories to includeEach report has its own categoriesEach category has its own level of detail

Choose custom separators for each new models, packages, components, etc.UML Reports can be customized
