Given the speed at which organizations are conducting business today, the promise of increased agility is making "Data Virtualization" a hot topic. However, as with all things, the devil's in the details. We need to go a bit beyond simply looking under the hood. Yes, data virtualization is an agile data integration approach that provides fast and direct access to new critical data that the business can trust and consume. That's all well said and done. However, it's a loaded statement. Each word, in fact, needs to be put under a microscope to make sure that simple data federation is not being passed off as data virtualization. Why? It's simple - the ROI just disappears. To do this correctly, we need to take a short trip down memory lane. Wayne Eckerson's blog on the TDWI website still remains one of the best sources of information on this subject. It pays due respec... (more)

Data - SOA's Last Mile

According to Wikipedia, “The last mile (or last kilometer) is the final leg of delivering connectivity from a communications provider to a customer. Usually referred to by the telecommunications and cable television industries, it is typically seen as an expensive challenge because ‘fanning out’ wires and cables is a considerable physical undertaking.” The significant complexity, cost, and risk associated with this situation delayed many broadband rollouts until new technology became available that could realize the “last mile.” This powerful and real-world analogy from the worl...

Data Virtualization – The Quest for Agility

Yes, data virtualization is definitely about agility. We covered this from different angles in my previous article. Agility in this context is about accelerating the time-to-delivery of new critical data and reports that the business needs and trusts. It is also about an architecture that is flexible to changes in underlying data sources, without impacting the consuming applications. It's about doing data virtualization the right way so you can deliver new critical data and reports in days vs. months. However, what about productivity? A discussion around agility cannot and must ... (more)

Extending Web Services to the Real World

This is the first in a series of articles that will explore the realm of Web services, the challenges that lie ahead, and advancements that enable extending Web services to the real world. Applications for real-world scenarios have significant dependencies on development time and ROI and must be robust, platform neutral, and performance sensitive. Most important, these scenarios need to be highly flexible to changes in requirements and applicability. Web services are an effective way to balance all these aspects of real-world applications and provide a rich and extensible infras... (more)

Web Services and Portal Technology

Portals are central points of access for applications and content for both internal and external use in an enterprise through interactive and rich presentation interfaces. Personalized access to information, applications, processes, and people is provided to portals by getting information from local or remote data sources such as databases, transaction systems, content providers, or remote Web sites. This information is then rendered and aggregated into meaningful pages to provide information to users in a compact and easily consumable form. In addition to pure information, many... (more)
