Next-Generation IDEs: The ILDE (or ALM)

Software development requires coordinated efforts- 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

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, deploym

ent, 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 Network- Operating system 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

Start with a Platform-Independent Model (PIM) representing business functionality and behavior, undistorted by technology details.

Platform-Independent

Model

A Detailed Model, stating Pre- and Post-Conditions in OCL, and Semantics in Action Language

Generating Platform-Specific Model


Model

Map a PIM to Specific Middleware

Technologies via OMG Standard Mappings

MDA tool applies a standard mapping to generate Platform-Specific Model (PSM) from the PIM. Code is partially automatic, partially hand-written.CORBA

Model

Mapping to Multiple Deployment Technologies


Model

CORBA Model

MDA tool applies an standard mapping to generate Platform-Specific Model (PSM) from the PIM. Code is partially automatic, partially hand-written.Java/EJB

Generating Implementations


Model

CORBA Model

MDA Tool generates all or most of the implementation code for deployment technology selected by the developer.

Map PSM to application interfaces, code, GUI

descriptors, SQL queries, etc.

Integrating Legacy & COTS

Automating Bridges

InteropBridge

MDA Tools combine

application and platform

knowledge to generate bridges

Bridge generation is simplified by common application models, simplifying creation of integrated applications both within and across enterprises.

MDA – Lifecycle Management

MDA Process所需元素

High level Model Standard, well-defined language for Model PIM to PSM transformation definition Formal language for transformation
