DEV337 Modeling Distributed Enterprise Applications Using UML in Visual Studio.NET David Keogh Program Manager Visual Studio Enterprise Tools

Agenda Why Model? Working with UML Generating Code Reverse Engineering Code Generating Reports

Session Prerequisites Experience developing Desktop or Web Applications on.NET Experience with Visual C# ™, Visual C++ ®, Visual Basic ®, or Visual Basic.NET Level 200

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?

Modeling Why 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

Visio Enterprise for Architects UML Model ++ Database Model ++ Gantt Chart Org Chart UML Model Database Model.etc Visio Professional Visio for Enterprise Architects Visio Engine Visio Standard Basic Diagram Basic Flowchart Basic Network.etc

Modeling Enterprise Architect Capabilities UML Software Modeling Full Support for the UML 1.2 Modeling Specification Reverse Engineer UML from existing Code Generate customizable code skeletons for Visual Basic, C++ and C# Automatic semantic error checking Customizable UML reports

Working with UML UML Defined UML is a language for: Visualizing Specifying Constructing Documenting the artifacts of a software-intensive system UML is an open standard Building blocks are elements, relationships and diagrams

Modeling using UML Diagram Types Structural Class Behavioral Use Case, State Chart, Activity, Sequence, Collaboration Implementation Component, Deployment

Working with UML Use Case Diagrams Use cases are commonly used to: Model the context of a system Model the requirements of a system Internet Customer Customer Account Management Purchase Books Product Catalog Search

Working with UML Sequence Diagrams Sequence diagrams are commonly used to: Model flows of control by time ordering : Web::book : BusinessFacade::ProductSystem : DataAccess::Books GetBooksByISBN() GetBooksByAuthor() GetBooksByNaturalLanguage() GetBooksBySubject() GetBooksByTitle() GetBookById()

Working with UML Additional Diagrams 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 Code The 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 Code Operations 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 Code Error 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 Reports Basics UML | Reports menu Allows you to generate a wide variety of reports Static Structure State Chart Component Deployment Activity Report presentation is customizable

Generating Reports Report Contents You can limit the scope of the report Base the report on: Active diagram Entire UML Model Specify object categories to include Each report has its own categories Each category has its own level of detail Choose custom separators for each new models, packages, components, etc. UML Reports can be customized

Generating Reports Additional Reporting Options  Save UML diagrams as a web page  HTML frame format  Tabs for navigating multiple diagrams  Embed diagrams in existing frames  Easy to publish information on an Intranet  Print or preview UML diagrams
