Time Studio. Galinier comments: “We
set up a benchmark for tools supporting
UML and this benchmark focused on two
sets of users; software engineers and systems
engineers. For software engineering,
the requirements included Jacobson
methodology support and automatic code
generation. For systems engineering, the
requirements included being able to
describe system architecture with
UML, the need for a good user interface,
documentation generation and simulation/
animation.”
Benefits:
The benefits of using UML for system
specification are two-fold. First, for systems
that are software centric, the use of UML
allows easy transition from the systems
engineers to the software developers. And
secondly, the behavioral model of UML is
based on Harel Statecharts – a well
defined executable language, which
means that a specification of a system in
UML can be executed and evaluated for
consistency, accuracy and fidelity before
it is partitioned into (amongst others)
mechanical, electronic and software
“blocks”.
Galinier resumes: “Systems engineering
is much more than just partitioning hardware
and software – systems also include
mechanical and optical components, and
it is crucial to be describing all of your
system if you are to see how it interacts.
For example, an infra-red camera is in
fact mechanics, optics, software and electronics
– and to describe the architecture
of the system, we use UML.”
On TTM’s recommendations, the
THALES’ shareholders have chosen to
adopt I-Logix’ Rhapsody for both software
and systems development. Rhapsody
automatically generates production-ready
code at any point in development. It does
this by employing a real-time execution
framework “beneath” the GUI, which
means Rhapsody can automatically generate
not only the source code, but also
make files and even invoke the compiler
and linker. As for Rhapsody’s use for systems
development, Galinier praises the
tool’s GUI and simulation capabilities.
But Rhapsody’s aptness for software
and systems generation was, according to
Galinier, only part of the reason I-Logix
was selected: “The tool’s selection is not
only based on technical satisfaction but
also on the tool provider – their world-wide
subsidiaries, and the level of technical
co-operation they can provide.We often
need to customize tools and for that we
need the help of I-Logix – for example to
set up interfaces with other tools such as
Telelogic’s requirements management
tool DOORS. In addition I-Logix is in the
process of introducing bridges based on
XMI™, the XML-based Model Interchange

It is all too easy to see how you
could soon have a situation where
whole teams are working in
different ways – unless you
standardize on tools and
methodologies across the entire
development organization.
In many organizations, objectoriented
techniques and the UML
are being used by systems engineers
to specify the architectural
structure of the overall system.
OMG MDA
Seminars Travel
to 7 Major Cities
Across the US
n accompaniment with OMG’s
Fall 2001 Model Driven Architecture
Seminar Series, OMG
launched a Spring Series during the first
week of April 2002. Traveling to Seattle,
San Diego, Dallas, Chicago, Atlanta, Philadelphia
and Washington, DC, the spring
Seminar Series reached new audiences
across the US. The goal was to inform and
educate the IT community about Model
Driven Architecture, OMG’s standard that
promises to extend software lifecycle to
twenty years and beyond.
The following presentations were
made at each free seminar;
• Model Driven Architecture:
An Introduction by Richard Soley,
Chairman and CEO of the OMG
• OMG MDA: An Idea Whose Time
Has Come by Paul Harmon, Senior
Consultant Distributed Architecture,
and eBusiness Service for Cutter
Consortium
• MDA Reality and Implementation
by David Frankel, Chief Consulting
Architect at IONA Technologies.
If you missed this most recent Seminar
Series but would like more information
about MDA, please visit our website for
an extensive overview and explanation of
the standard, as well as for case studies
and cutting-edge products/services that
currently implement Model Driven Architecture.
