Big Data

The well-known three Vs of Big Data - Volume, Variety, and Velocity – are increasingly placing pressure on organizations that need to manage this data as well as extract value from this data deluge for Predictive Analytics and Decision-Making. Big Data technologies, services, and tools such as Hadoop, MapReduce, Hive and NoSQL/NewSQL databases and Data Integration techniques, In-Memory approaches, and Cloud technologies have emerged to help meet the challenges posed by the flood of Web, Social Media, Internet of Things (IoT) and machine-to-machine (M2M) data flowing into organizations.

EMC Greenplum has qualified Attunity RepliWeb for Enterprise File Replication (EFR) and Attunity Managed File Transfer (MFT) with EMC Greenplum Hadoop (HD). Attunity RepliWeb for EFR and Attunity MFT are high-performance, easy-to-use solutions for automating, managing and accelerating the process of making data available for big data analytics with Hadoop. According to Attunity, the products, launched earlier this year, are the first and only solutions currently qualified by EMC for Greenplum HD. "Greenplum has come into the marketplace by storm and has had a strong vision of being data-independent or data-agnostic. They want to make sure that their analytic platform can handle both structured and unstructured data and this aligns very well with Attunity's mission statement of any data, any time, anywhere," Matt Benati, vice president of Global Marketing at Attunity, tells DBTA.

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."

For many years, enterprise data center managers have struggled to implement disaster recovery strategies that meet their RTO/RPOs and business continuity objectives while staying within their budget. While the challenges of moving, managing, and storing massive data volumes for effective disaster protection have not changed - exponential data growth and the advent of big data technologies, have made the challenge of disaster recovery protection more difficult than ever before.

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.

For years, data warehouses and extract, transform and load (ETL) have been the primary methods of accessing and archiving multiple data sources across enterprises. Now, an emerging approach - data virtualization - promises to advance the concept of the federated data warehouse to deliver more timely and easier-to-access enterprise data. These are some of the observations made at Composite Software's third Annual Data Virtualization Day, held in New York City. This year's gathering was the largest ever, with nearly 250 customers and practitioners in attendance, Composite reports.

For a long time, data integration has been the holy grail for data organizations, promising a single, accurate picture of relevant data from across the enterprise, regardless of original source or format. Now, with the rise of new approaches — including master data management (MDM) and data virtualization, there is hope that this goal is within reach. But the challenges keep on coming, and lately, there has been a surge in unstructured data that may fall outside MDM realms.

The first computer program I ever wrote (in 1979, if you must know) was in the statistical package SPSS (Statistical Package for the Social Sciences), and the second computer platform I used was SAS (Statistical Analysis System). Both of these systems are still around today—SPSS was acquired by IBM as part of its BI portfolio, and SAS is now the world's largest privately held software company. The longevity of these platforms—they have essentially outlived almost all contemporary software packages—speaks to the perennial importance of data analysis to computing.

The term "big data" refers to the massive amounts of data being generated on a daily basis by businesses and consumers alike - data which cannot be processed using conventional data analysis tools owing to its sheer size and, in many case, its unstructured nature. Convinced that such data hold the key to improved productivity and profitability, enterprise planners are searching for tools capable of processing big data, and information technology providers are scrambling to develop solutions to accommodate new big data market opportunities.

Organizations are struggling with big data, which they define as any large-size data store that becomes unmanageable by standard technologies or methods, according to a new survey of 264 data managers and professionals who are subscribers to Database Trends and Applications. The survey was conducted by Unisphere Research, a division of Information Today, Inc., in partnership with MarkLogic in January 2012. Among the key findings uncovered by the survey is the fact that unstructured data is on the rise, and ready to engulf current data management systems. Added to that concern, say respondents, is their belief that management does not understand the challenge that is looming, and is failing to recognize the significance of unstructured data assets to the business.

Big Data. It's a term used to characterize those applications that have such enormous data sets, they have exceeded the capabilities and capacities of traditional database management systems. These huge data sets-measured in terabytes, petabytes, exabytes, and zettabytes-must instead span large clusters of servers and storage arrays. Search engine companies were the first to face this situation, and the result is an open source solution called Hadoop.

"Big data" and analytics have become the rage within the executive suite. The promise is immense - harness all the available information within the enterprise, regardless of data model or source, and mine it for insights that can't be seen any other way. In short, senior managers become more effective at business planning, spotting emerging trends and opportunities and anticipating crises because they have the means to see both the metaphorical trees and the forest at the same time. However, big data technologies don't come without a cost.

Google's first "secret sauce" for web search was the innovative PageRank link analysis algorithm which successfully identifies the most relevant pages matching a search term. Google's superior search results were a huge factor in their early success. However, Google could never have achieved their current market dominance without an ability to reliably and quickly return those results. From the beginning, Google needed to handle volumes of data that exceeded the capabilities of existing commercial technologies. Instead, Google leveraged clusters of inexpensive commodity hardware, and created their own software frameworks to sift and index the data. Over time, these techniques evolved into the MapReduce algorithm. MapReduce allows data stored on a distributed file system - such as the Google File System (GFS) - to be processed in parallel by hundreds of thousands of inexpensive computers. Using MapReduce, Google is able to process more than a petabyte (one million GB) of new web data every hour.
