Triangle Java Users Group Presents:

How to Eat an SOA: Using Dynamic Composition to Build Composite Applications

presented by Matthew Adams

6:30 PM - 9:00 PM

4001 E. Chapel Hill-Nelson Highway
Research Triangle Park, North Carolina

Abstract:
As SOAs become more and more prevalant, much of the focus among developers and vendors has been on how to build services, but not so much on how to consume them. In a realistic composite application, there is much more than a web service or two that must be accessed; there are often multiple services implemented in differing technologies, as well as multiple databases, relational or otherwise. Dynamic composition makes building composite applications easier by leveraging metadata about databases' and services' behavior in order to calculate workflow at runtime, instead of today's more common practice of doing so at design time. The benefits of leveraging dynamic composition include the ability to pursue a truly business level data and/or object model, much simpler transactional control, and the ability to encapsulate but still directly communicate with the underlying resources without introducing a message queue and the associated development and message marshaling overhead.
