Next-Generation IDEs: The ILDE (or ALM)
 Software development
requires coordinated
efforts
Mobilising Developers
- Traditional tools set up
boundaries that match titles
- Pass it along coordination
 Growing use of global
development teams
- Round-the-clock change
 Think of tools as
“portals” that coordinate
efforts
Tools must be matched with processes to ensure
effective collaboration and meet business requirements

What is Model Driven Architecture?
 A New Way to Specify and Build Systems
- 2001年由OMG制定的新开发架构
- 以UML塑模为基础
- 支持完整开发周期 : analysis, design, implementation,
deployment, maintenance, evolution & integration with later
systems
- 内建协同运作性及跨平台性
- 降低开发初期成本及提高 ROI
- 可套用至你所使用的任何环境 :
- Programming language
- Operating system

Network

Middleware
Model Driven Architecture
UML(Unified Modeling Language)
MOF(Meta Object Factory) : OMG
标准，与UML相关，针对 metadata
management及modeling language
definition
CWM(Common Warehouse
Metamodel) : OMG规格对 data
repository integration
提升 UML 是重要关键
 UML 延续90年代初期的多项OOAD方法(OOSE-Object
Oriented Software Engineering, OMT-Object
Modeling Technique)
 OMG于96年采用，并于97年完成规格制定
 另制定如MOF以及XML Metadata specs (XMI)加以补
充
 标准化后，亦造就了市场
- 超过 100 本书籍
- 十数种商业开发工具
- 普遍开设的教育训练
 Supported by an open process
- UML 2.0 process under way now
Building an MDA Application
PlatformIndependent
Model
A Detailed Model,
stating Pre- and PostConditions in OCL,
and Semantics in
Action Language
Start with a PlatformIndependent Model
(PIM) representing
business functionality
and behavior,
undistorted by
technology details.

generate PlatformSpecific Model (PSM)
from the PIM. Code is
partially automatic,
partially hand-written.
