Data virtualization is a data integration approach used by innovative organizations to achieve business agility.
Do you want to achieve similar gains, but are unsure where to apply data virtualization?
There is no need to guess. Follow the leaders down one or more of the five paths to data virtualization success.
Five Popular Data Virtualization Usage Patterns
Data virtualization is a versatile data integration solution that can be deployed to solve a wide range of data integration challenges. Based on nearly ten years of successful implementations, several common usage patterns have emerged to help guide your enterprise's data virtualization adoption strategy.
These data virtualization usage patterns include:
- BI data federation
- Data warehouse extension
- Enterprise data virtualization layer
- Big data integration
- Cloud data integration
Let's briefly examine each one.
BI Data Federation
Historically, BI data federation has been the most popular data virtualization starting point. Data virtualization is an excellent way to expand BI reporting to sources beyond the existing cubes or data marts. Popular BI vendors such as IBM Cognos and SAP Business Objects have promoted this approach and even embedded data virtualization offerings in their BI solutions to simplify this method of adoption. The benefits of this approach include both more complete and actionable information and faster time-to-solution.
Data Warehouse Extension
Extending the data warehouse has gained popularity in recent years as another starting point for adopting data virtualization. In the struggle to maintain data warehouses and keep pace with accelerating business and technology changes, IT organizations have adopted data virtualization as effective way to augment warehouse data. Examples include augmenting internal warehouse data with external data, combining last night's warehouse data with today's data and complementing summarized warehouse data with detailed drill-down data. Data warehouse prototyping, federating multiple warehouses after a merger and support for data warehouse migration are additional sub-patterns within the data warehouse extension approach. Beyond information and agility value, enterprises also increase their return on prior data warehouse investments.
Enterprise Data Virtualization Layer
Once comfortable with the initial, project-oriented data virtualization deployments, the next step is often deploying a more enterprise-wide data virtualization layer. A data virtualization layer combines SOA principles, such as decoupling, reuse, and agility, with key information governance principles, such as abstraction, shared semantic models and data standards, to enable IT to build and deploy a layered, enterprise-wide data architecture in a simpler, faster, more consistent and scalable manner.
Big Data Integration
Big data integration has recently emerged as a popular data virtualization pattern driven by enterprises' rapid adoption of analytics. Most of these analytics run on new "Big Data" data stores such as Hadoop and analytic data warehouse appliances such as IBM Netezza. Once these new stores are in place, organizations soon realize they can gain additional insight if they integrate these new big data silos with their existing enterprise data. This is where data virtualization comes in, providing a rapid integration approach that doesn't require additional replication of already "big" data sources.
Cloud Data Integration
Cloud data integration has also recently emerged as a popular data virtualization pattern as enterprises take advantage of new Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS) offerings. However, each new cloud source and consumer must be integrated with the existing IT environment - a problem that data virtualization is ideally architected to solve.

This contrasts with conventional software development that begins with defining logic based on the current way a business operates. In her session at 18th Cloud Expo, Judith S. Hurwitz, President and CEO of Hurwitz & ...

As enterprises work to take advantage of Big Data technologies, they frequently become distracted by product-level decisions. In most new Big Data builds this approach is completely counter-productive: it presupposes tools that may not be a fit for development teams, forces IT to take on the burden of evaluating and maintaining unfamiliar technology, and represents a major up-front expense. In his session at @BigDataExpo at @ThingsExpo, Andrew Warfield, CTO and Co-Founder of Coho Data, will dis...

Eighty percent of a data scientist’s time is spent gathering and cleaning up data, and 80% of all data is unstructured and almost never analyzed. Cognitive computing, in combination with Big Data, is changing the equation by creating data reservoirs and using natural language processing to enable analysis of unstructured data sources. This is impacting every aspect of the analytics profession from how data is mined (and by whom) to how it is delivered. This is not some futuristic vision: it's ha...

Most people haven’t heard the word, “gamification,” even though they probably, and perhaps unwittingly, participate in it every day. Gamification is “the process of adding games or game-like elements to something (as a task) so as to encourage participation.” Further, gamification is about bringing game mechanics – rules, constructs, processes, and methods – into the real world in an effort to engage people. In his session at @ThingsExpo, Robert Endo, owner and engagement manager of Intrepid D...
