Service-Orientation vs. Object-Orientation: Understanding the Impedance Mismatch
by Larry Guger
Object-oriented programming languages and techniques provide a powerful means for designing and building applications. These techniques do not always translate well into a service-oriented paradigm. Service-orientation demands a different set of design guidelines and requirements than object-oriented design approaches because we are essentially outfitting programs with new characteristics in support of new goals. Understanding how an object-oriented design can negatively impact a service-oriented design is key to building services that support an agile enterprise. This article examines where the two designs impact each other as well as methods for addressing their incompatibilities (which we refer to as the "impedence mismatch") while still leveraging opportunities to use them together...

Data Management:
The Missing Link in Your SOA Strategy
by David Butler
and Jeff Pollock
SOA is only as good as the data it leverages. Bad data has ruined too many enterprise software projects. Data Management encompasses data integration together with master data management (MDM) which addresses the governance of data-centric environments. MDM aims to improve business data quality while providing a single, unified view of that data. How can an SOA leverage such a single view? The bridge that ties these seemingly disparate paradigms together is data integration, which combines the data-centric elements of both SOA for data services and MDM foundational techniques for data quality, data profiling, and data relationship management. When used together in this way, organizations can reap a sizeable and sustainable competitive advantage as a result of flexible information architectures and flexible authoritative data.

An SOA Vendor Evaluation Methodology
by Alex Roussekov
This article describes a methodology for evaluating SOA vendors that, when applied to analytical sources such as Gartner and Forrester, can help shortlist appropriate vendors in an objective manner. This objectivity is ensured by a ranking and scoring system based on a set of evaluation criteria within the corresponding evaluation models. The evalutation process is based on the analysis of results from studies carried out over the past year identifying the "Best-of-Breed" vendors available in the SOA market, according to both Gartner and Forrester. Toward the end of this article I consolidate all of the results using a simple formula that produces a final short list is revealed based on the correlation between preceding short lists obtained from each model. The results of this article can help you assess how vendors fared in reltion to this criteria and to also help you develop your own assessment methodology...
