Understanding MDA

>apropos alberto.lagna

• Computer Science graduate, Telco master• Independent consultant, working as software architect /

team leader• Consulting on design and development of enterprise

systems mainly based on JavaEE.• 15 years of working experience (2 big MDA projects):

– IT asset repository in a big bank– MDA tool for software vendor

• JUGTorino member• Promoting the use of free software and supporting the open

source movement


The Problem

• Business is more demanding– Market ‘mutates’ constantly– New kinds of products needed – fast!– Many new products require new (and innovative) IT solutions

• But:– IT platforms also mutate constantly– Legacy systems are tied to legacy platforms– IT has no universal integrating paradigm– So, IT culture is constantly tied up in maintenance and therefore

slow to respond to change• Result:

– Business-IT relationship under strain– Individual projects have high costs and high risk of failure– Projects not well-coordinated; no reuse


Contributing Factors

• Business does not describe its needsand opportunities in a consistent way

• Business and IT speak very different‘solutioning’ languages

• IT does not follow consistentprocesses for creating, acquiring,integrating and customizing software

• IT solutions are standalone; littlereuse

• Existing layers of legacy software,hardware and ‘muddleware’compound all of the above.


Is There a Better Way?

• Much more rapid time-to-market

• Significantly improvedsolutions quality

• Significantly lower solutionslifecycle costs

• End-to-end traceability –requirements to deployment

• Improved overall business-ITalignment

Software Implementer

•Separation of concerns•Multiple viewpoints•Multi-level reuse•Precise information flows•Full traceability


Why MDA?

• Based on proven best practices and openstandards

• Supported by 900+ OMG members• Widely implemented in commercial and

open source tools• Applicable to a wide range of business

and computing problems• Highly adaptable to different

organizations, project types, toolsets,technologies, etc.

• Supports all forms of development anddeployment, including outsourcing and off-shoring


Who is Using MDA?

• Government• Financial Services• Aerospace, Defense• E-commerce• Telecomm• Manufacturing• Biomed• ……. (see www.omg.org/mda)

MDA tools and frameworks

• which one do I have to choose?• which has the best fit to my requirements?• what are my requirements?


Realistic Concerns

• Can it really work at ourcompany?

• How much time/money could itsave?

• Is it really worth the time, cost,effort and risk to implement?

• What will the ‘to-be’ state of ourorganization really look like?

• How do we manage/govern ourorganization’s transition to MDA

• How do we get started?

MDA tool requirements

• for YOUR target platform– supports custom metamodels

• addresses full lifecycle– metamodels, tranformation, generation

• Advanced capabilities– reverse eng, versioning, validation, simulation

• integration with tools• standard conformance


MDA products fulfilling reqs

• Commercial– Compuware OptimalJ– IO Arcstyler

• Open Source– AndroMDA– OpenArchitectureWare


Compuware OptimalJ

• Metamodels– Domain Model, highest level of abstraction– Application Model, the application architecture– Code Model, the syntactically precise code

• Technology patterns– transformation Domain Model -> the Application

Model.• Implementation patterns

– transformation Application Model ->Code Model.


Compuware OptimalJfeatures


Interactive ObjectsArcStyler

• Pluggable and fully extensible MDACartridges:– Java5 – Web Services (J2EE 1.4 and EJB 2.1)

• BEA WebLogic 8.1 • IBM WebSphere 5.1 • JBoss 4

– .NET – web applications

• Struts


AndroMDA

• Contains a toolkit for building your own cartridges orcustomize existing ones

• Building blocks of AndroMDA are pluggable and canbe exchanged to meet your needs

• Validates the input models using OCL constraintswhich are related to the metamodel classes.

• Ready-to-use cartridges for common enterprisearchitectures (EJB 2/3, Spring, Hibernate, Struts,JSF, Axis, jBPM, .NET)


Open ArchitectureWare

• Powerful engine allowing the definition ofgenerator/transformation workflows.– Check, OCL-like language, supporting declarative definition

of constraints– Xtend, functional model transformation language– Xpand2, powerful template language– Recipe Framework define validation rules for artefacts

created outside of the generator– Xtext Framework define a textual modelling language using

a simple BNF-like notation.

• Lack of pre-built MetaModels


What really makes thedifference

…among the different products– availability of MetaModels to support

transformations– speed in updating support for upcoming

technologies, standards, approaches– extensibility of MetaModels
