SOA is all about reuse and leveraging existing investments, according to Ian Thain,  senior technical evangelist / software engineer in the Worldwide Marketing Organization of Sybase, Inc. In Thain's view, "model-driven SOA" allows for an intersection between requirements established as services and their implementation based on existing infrastructure and new components.

Thain will be giving a session about Model-Driven SOA at SOAWorld Conference & Expo 2007 West, being held 12-13 November 2007 at the Grand Hyatt Hotel in San Francisco.

In traditional application architectures, he will explain, the design phase in the Software Development Life Cycle (SDLC) plays a critical role in enabling well-architected solutions.

"Yet there hasn't been much discussion about the design or the modelling phase of SOA-based applications," note Thain. "Translating the business requirements into services and service models allows for leveraging services throughout the lifecycle. This also allows for mapping the services to an implementation architecture of right nature which could be based on component model like EJB or a simple database infrastructure."

Model-Driven SOA enables the business visibility into IT by making the changes visible in both directions, requirements and implementation. A demo will be using Sybase WorkSpace.
