Data keeps growing, systems and servers keep sprawling, and users keep clamoring for more real-time access. The result of all this frenzy of activity is pressure for faster, more effective data integration that can deliver more expansive views of information, while still maintaining quality and integrity. Enterprise data and IT managers are responding in a variety of ways, looking to initiatives such as enterprise mashups, automation, virtualization, and cloud to pursue new paths to data integration. In the process, they are moving beyond the traditional means of integration they have relied on for years to pull data together.

Today's data warehouse environments are not keeping up with the explosive growth of data volume (or "big data") and the demand for real-time analytics. Fewer than one out of 10 respondents to a new survey say their data warehouse sites can deliver analysis in what they would consider a real-time timeframe. Nearly 75% of respondents believe that in-memory technology is important to enabling their organization to remain competitive in the future. Yet, almost as many also indicate they lack the in-memory skills to deliver even current business requirements. These are among the findings of a new survey of 323 data managers and professionals who are part of the Independent Oracle Users Group (IOUG). The survey was underwritten by SAP Corporation and conducted by Unisphere Research, a division of Information Today, Inc.

Databases are hampered by a reliance on disk-based storage, a technology that has been in place for more than two decades. Even with the addition of memory caches and solid state drives, the model of relying on repeated access to the permanent information storage devices is still a bottleneck in capitalizing on today's "big data," according to a new survey of 323 data managers and professionals who are part of the IOUG. Nearly 75% of respondents believe that in-memory technology is important to enabling their organization to remain competitive in the future. Yet, almost as many also indicate they lack the in-memory skills to deliver even current business requirements. The research results are detailed in a new report, titled "Accelerating Enterprise Insights: 2013 IOUG In-Memory Strategies Survey."

Despite the rise of big data, data warehousing is far from dead. While traditional, static data warehouses may have indeed seen their day, an agile data warehouse — one that can map to the needs of the business and change as the business changes — is quickly on the rise. Many of the conversations today around big data revolve around volume and while that is certainly valid, the issue is also about understanding data in context to make valuable business decisions. Do you really understand why a consumer takes action to buy? How do their purchases relate? When will they do it again? Big data is limited when it comes to answering these questions. An agile approach — one that gives even big data a life beyond its initial purpose — is the value data warehousing can bring to bear and is critical to long-term business success.

Big data is here, offering both vast opportunities — as well as vexing challenges — for every organization it touches. For a number of years, it has been understood that to be of value, information needs to be readily available, as close to real time as possible, to users in any location. Now, with the onset of "big data," the task gets more daunting. "These are all increasing the demands on both transactional and analytics data systems," says Bernie Spang, director of database software and systems for IBM.

Are today's data systems — many of which were built and designed for legacy systems of the past decade — up to the task of moving information to end users at the moment they need it? And is this information timely enough? In many cases, there's a lot of work that still needs to be done before real-time information, drawn from multiple sources, becomes a reality. A new survey of 338 data managers and professionals who are subscribers to Database Trends and Applications reveals that real-time data access is still a distant pipe dream for at least half of the companies represented in the survey. The survey, conducted by Unisphere Research, a division of Information Today, Inc., in partnership with Attunity in March of 2012, finds that close to half of the survey respondents, 48%, report that relevant data within their organizations still take 24 hours or longer to reach decision makers. This suggests that much data is still batch-loaded overnight.

The opportunities and challenges presented by big data are examined in a new survey of 298 data managers and professionals who are part of the Independent Oracle Users Group. The survey was underwritten by Oracle Corporation and conducted by Unisphere Research, a division of Information Today, Inc. According to this new survey, more than one out of 10 data managers now have in excess of a petabyte of data within their organizations, and a majority of respondents report their levels of unstructured data are growing. Fewer than one out of five respondents feel their IT infrastructure will be ready to handle this incoming surge of data. Protecting data overall is important, but unstructured data gets low priority at this time.
