Well, maybe you shouldn’t’

But then, maybe you should

Maybe you have to

Modeling is the standard approach in engineering to Manage Complexity

Mitigate Risk

Software development is the same asevery other kind of engineering in this respect

Code and other artifacts can be derived from models

Model Driven DevelopmentDelivering innovation and collaboration


7

Business Model

Visualization of business processes

System Architecture Model Visualization of the system

requirements, structure, and behavior

Use Case Model

Visualization of functional requirements

Analysis Model

“What” the system must do to realize the functional requirements with the system

Design Model

“How” the system will realize the functional requirements

Data Model

Visualization of persistent storage

Implementation Model

Visualization of the code

What types of models are important?Different Stakeholders, Different Models

User Experience Model

Visualization of user interaction with the system


8

Model-driven development is aided by acommon language across all stakeholders

Unified Modeling Language (UML) is the standard language for visualizing, specifying, constructing, and documenting the artifacts of a software-intensive system

UML allows software architects, designers and developers to specify, visualize, construct, and document all aspects of a software system

Extensible to support evolving modeling needs Allow expression of concepts and aspects common to industry or

standard

Limit modeling environment to only what is necessary

UML: The Language of Model Driven DevelopmentStandard and extensible

Challenge: Manage Complexity


11

Challenge Overcome the problem of communicating solution to a

team

Resolution Provide technologies to enable

effective communication of a design

UML 2 Notation

Domain specific modeling language extensions

Integrate the architecture artifacts into the development environment

Provide Global Access to artifacts internally and for suppliers

Challenge: Communicate Architecture


12

Challenge How can teams learn about the architecture of existing

implementations or frameworks?

Resolution

Provide an automated means for discovering architecture

Look for Anti-Patterns

Visualize complexity

Challenge: Discover complexity


13

Challenge

How to enforce architecture decisions for a project team?

Resolution

Generate source-code based on architecture decisions

Create and enforce rules which support the architecture

Process Guidance

Code rules

Visually compare model changes

Link requirements to design and to derived artifacts like code

Challenge: Enforce Architecture Standards

classes and structs

C/C++ editor with syntax highlighting,

code completion, and advanced search

Key Feature: C/C++ Development Environment


19

Editing and Navigation

C/C++ Syntax Highlighting, Outline View

C++ Class Browser (Hierarchy View)

C/C++ Search

C/C++ Content Assist

Project Import

Automated assistance in setting up CDT for search and content assist.

UML C/C++ Code Editor

Debug

Standard Make for projects with existing build infrastructure

Managed Build

Automatic makefile generation

GNU tools supported out of box

Managed build is extensible, build tools can be plugged-in and build tools options selectable

Meets Internationalization and Accessibility requirements

Extensibility

Provides extension points for managed build, debuggers, …

Key Feature: C/C++ Development Environment


20

Simplify the capture of UML models during Analysis and Design

Make modeling more accessible to a broader audience

New custom views improve the editing experience

New “Diagram Navigator” view provides a diagram

filtered view of the models and workspace

Diagram links as first-class citizens

“In diagram editing” to accelerate

modeling.

New properties view

Inheritance view

Key Feature: Modeling assistance


21

Applying Patterns is very simple Evolution of pattern experience

based on lessons learned

Pattern-authoring provides greater flexibility using Open API

All Gang of Four design patterns provided

Additional patterns provided via RAS repository on IBM developerWorks

the pattern

Pattern rendered as a collaboration to

support incremental application

Support “drag-and-drop” of pattern parameters into the collaboration

Key Feature: Patterns

Transformations are optimal for “batch” style computationally intensive operations Model-to-model

Model-to-code

Code-to-model
