Why Model-Driven Development?


The Architect will do the first high level drawings to validate the concept, then make a detailed plan for the Builders

The Builders will take this blueprint and optimize it based on technical constraints

Would You Build a House Without a Blueprint?

为什么要使用模型驱动开发工具 ? (1/2)


为什么要使用模型驱动开发工具 ? (2/2)

用户的问题 :1. 怎样提高软件质量 , 缩短开发周期 , 并且方便维护 ?

2. 怎样提高投资回报率 ?

3. 怎样使软件更能够适应业务需求的变化 ?

解决办法 : 软件应用系统的开发离不开应用设计，应用设计离不

开建模工具，好的建模工具可以帮助你提高应用软件的质量，降低风险

PowerDesigner/WorkSpace 就是一种这样的应用开发设计工具。


What’s Model-Driven Development?

Model-Driven Development Define models, generate code from models instead of writing code

by hand

Modeling has evolved in the past years Still means traditional Analysis and Design, a-la CASE Tools Emergence of « Model-driven development » and «Model-Driven

Architecture »: do more modeling, write less code

Especially true for UML – two use cases: Analysis and Design – capture and specify business needs Visual coding – class and sequence diagrams used by code

developer for better productivity

In a nutshell, more technical modeling, but not more Analysis and Design.


What’s Model-Driven Architecture?

Model-Driven Architecture (MDA) MDA is defined by Object Management Group (OMG)

Platform Independent Model (PIM)

Platform Specific Model (PSM)

Model-to-Model Transformation (PIM->PIM, PIM->PSM, …)

Code generation using templates or design patterns

Simplify Development

Several Ways to Simplify Development Simplify language (improve Java, .NET, new languages)

EJB 3, O/R mapping with POJO, metadata annotation, Generics, … Aspect-Oriented programming, Ruby on Rails, …

Design patterns Inversion of Control (IoC), Spring framework, …

Visual Development Use Visual Editors instead of code editors

Model-Driven Development Define models, use models to generate code

Service-Oriented Architecture Expose functionalities as services, assemble services


Enterprise Modeling: Convergence of BP, UML and Data Modeling

Business Process Modeling ( 企业流程建模 ) 企业用户 , CIOs

UML Modeling ( 面向对象建模 ) IT 用户 , 分析员 , 设计师 , 开发人员

Data Modeling ( 数据建模 ) IT 用户 , 分析员 , 设计师 , DBAs

In the past, companies used different tools.It is difficult de manage common metadata and impact analysis.The three modeling techniques are converging.


Strategic Planning, SPA-21-5951 - M. Blechar

Predicts 2004: BPA, UML and Data Modeling Converge

« Techniques such as business process analysis are converging

to provide technical architects, business modelers, developers

and database designers consistency, productivity and quality via

reuse and code automation. »

« …Vendors such as Sybase (PowerDesigner) and … offer

single products that span all three markets. Most UML modeling

tool vendors already have some BPA and database design

support in their tools, and vice versa. … »
