Why Model-Driven
Development?
Sybase Confidential Propriety.
Sybase Confidential Proprietary.
为什么要使用模型驱动开发工具? (1/2)
Would You Build a House Without a Blueprint?
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

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

11
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.

Enterprise Modeling: Convergence of
BP, UML and Data Modeling
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. … »
