Trends and Applications

It is an understatement to say we're witnessing an example of Moore's Law — which states the number of transistors on a chip will double approximately every two years — as we seek to manage the explosion of big data. Given the impact this new wealth of information has on hundreds of millions of business transactions, there's an urgent need to look beyond traditional insight-generation tools and techniques. It's critical we develop new tools and skills to extract the insights that organizations seek through predictive analytics.

When virtualization was first born, IT departments went gangbusters using this revolutionary change to get better performance out of their servers. In all the excitement of implementation, something not so very small was overlooked — backup and recovery. The lack of proper planning forced jobs and recovery to fail, and backup admins started feeling backed into a corner. Thankfully, times have changed, and IT departments, now very aware of these issues, have gotten savvy at avoiding the potential pains of virtualization infrastructure. But a new challenge has emerged.

It's in the nature of hype bubbles to obscure important new paradigms behind a cloud of excitement and exaggerated claims. For example, the phrase "big data" has been so widely and poorly applied that the term has become almost meaningless. Nevertheless, beneath the hype of big data there is a real revolution in progress, and more than anything else it revolves around Apache Hadoop. Let's look at why Hadoop is creating such a stir in database management circles, and identify the obstacles that must be overcome before Hadoop can become part of mainstream enterprise architecture.

Google is the pioneer of big data. Technologies such as Google File System (GFS), BigTable and MapReduce formed the basis for open source Hadoop, which, more than any other technology, has brought big data within reach of the modern enterprise.


Columns - Database Elaborations

The beauty of a truly wonderful database design is its ability to serve many masters. And good database designers are able to empathize with those who will use their designs. In business intelligence settings, three perspectives deserve consideration when composing designs.

As businesses push to reduce the data latency between analytical systems and operational systems, data warehouses begin to take on more of the character of a transactional system. For a data warehouse to deliver near real-time information, the choices generally are to update the warehouse more frequently or access data directly from operational systems. Either way, the push to reduce latency changes the nature of database performance to support the data warehouse. The main reason we created data warehouses in the first place was to separate resource-intensive analytical processing from shorter duration, but very frequent transaction processing. As the two worlds now come back together, the churn pressure on the database system can be significant.

Fall is my favorite time of the year for a lot of reasons. I love the cooling temperatures and the falling leaves. I enjoy the fall sports and school activities of my kids. And, perhaps best of all, I get to enjoy the yearly high-point for SQL Server professionals, the annual Community Summit put on by the Professional Association for SQL Server (www.sqlpass.org).For a technologist, the reasons to attend the annual conference of your profession should be self-evident. At the PASS 2012 Summit, there are nearly 200 technical sessions from beginner to advanced level over the duration of the week of November 5.
