Jon Siegel
OMG's (Object Management Group) Model Driven Architecture
Wednesday October 30, 2002
Building 3 Auditorium - 3:30 PM
(Refreshments at 3:00 PM)

Dr. Jon Siegel, will talk about OMG's (Object Management Group) Model Driven Architecture. Because each middleware platform works best in a particular network niche (such as behind the firewall, or over the Internet), today’s enterprise must deal with a multitude of platforms and connectivity paradigms.

OMG’s (Object Management Group) new Model Driven Architecture (MDA) unifies and simplifies this environment by defining software fundamentally at the model level, expressed in the standard Unified Modeling Language (UML). An application’s base model specifies every detail of its business functionality and behavior in a technology-neutral way. Working from the base model, MDA tools use OMG-standard mappings to generate interfaces and most or all of the implementation code for one or more target middleware platforms. Tools also generate cross-platform invocations, allowing easy interworking with other applications wherever they reside. MDA supports applications over their full lifecycle starting with design and moving on to coding, testing, and deployment, through maintenance, and eventually to evolution to a new platform when an application’s exisiting platform becomes obsolete. Another benefit: because industry standards defined in the MDA are platform-independent, they can be used by every enterprise even in industries that have not converged on a single middleware platform. The MDA became the base architecture for OMG standards in September 2001.

Dr. Jon Siegel, OMG’s Vice President of Technology Transfer, heads OMG’s technology transfer program with the goal of teaching the technical aspects and benefits of the Model Driven Architecture (MDA) based on OMG’s modeling specifications UML, the MOF, XMI, and CWM. Dr. Siegel’s scope includes OMG’s industry-standard middleware, the Common Object Request Broker Architecture (CORBA) and the Object Management Architecture (OMA) comprised of the CORBA services, the CORBAfacilities, and the domain specifications in vertical markets ranging from healthcare, life sciences, and telecommunications to manufacturing and financial systems. In this capacity, he presents tutorials, seminars, and company briefings around the world. Dr. Siegel has written magazine articles and books including the popular, CORBA 3 Fundamentals and Programming and Quick CORBA 3. With OMG since 1993, Siegel previously chaired the Domain Technology Committee responsible for OMG specifications in the vertical domains.
