March 29, 2013 – We study fifteen months of human mobility data for one and a half million individuals and find that human mobility traces are highly unique. In fact, in a dataset where the location of an individual is specified hourly, and with a spatial resolution equal to that given by the carrier's antennas, four spatio-temporal points are enough to uniquely identify 95% of the individuals.
March 13, 2013 – In February 2013 EMC Corporation released a new distribution of Apache Hadoop – Pivotal HD. Pivotal HD includes built-in integration with EMC’s Greenplum analytical database with Apache Hadoop. This ENTERPRISE MANAGEMENT ASSOCIATES® (EMA™) Impact Brief covers the announcement and identifies the Pivotal HD Hadoop distribution as a major step toward integrating multi-structured data with existing structured data infrastructures, such as business intelligence and analytical platforms.
March 13, 2013 – EMC Greenplum announced a new Hadoop distribution, Pivotal HQ, and a relational database using Greenplum Database technology that runs directly on Hadoop called HAWQ. By providing SQL support directly in Hadoop, EMC Greenplum has productized Hadoop and developed an easier path for traditional SQL-based companies to start using Big Data.
March 1, 2013 – HAWQ is a parallel SQL query engine that combines the key technological advantages of the industry-leading Greenplum Database with the scalability and convenience of Hadoop.
February 25, 2013 – For most enterprises, Big Data has moved from being just a buzzword or a science project to the recognition that Big Data can generate tactical and strategic competitive advantage as well as being a value creator for the business. There are plenty of choices in terms of the underlying hardware technology; a variety of Hadoop distributions or NoSQL databases; and numerous technologies that help enterprise enable internal datasets to be integrated with external datasets.
January 22, 2013 – In the normal course of any year, The Bloor Group is briefed by a fairly large spectrum of technology vendors, spanning most areas of information technology, from the iron to the applications. Typically, we encounter many new approaches to established technologies and services. Occasionally we encounter technologies that, although they might not be entirely original, are sufficiently different to surprise us.
January 22, 2013 – No Longer Just a Scale-Out Database. The Greenplum Database is one that rose to prominence fairly recently in a new wave of scale-out SQL databases, most of which were built as column stores. In fact Greenplum is not a pure column store, describing itself as polymorphic – which means that it offers the choice of column or row-oriented storage. Tables can also be configured to optimize read/write operation.
December 10, 2012 – With the rise of Big Data awareness and analytics technology, the digital universe in 2012 has taken on the feel of a tangible geography — a vast, barely charted place full of promise and danger. The digital universe lives increasingly in a computing cloud, above terra firma of vast hardware datacenters linked to billions of distributed devices, all governed and defined by increasingly intelligent software.
December 7, 2012 – Smart Cities are all about collaboration, sharing and transparency. They need true openness of data. It is not just governments opening up their data for everyone in public platforms. It is individual citizens and privately-owned companies offering their data to the government or government departments sharing their data with one another. That is the true meaning of ‘Open Data’, which goes beyond the traditional definitions. Because Smart Cities eat the ‘status quo’ for breakfast. They change at the speed of light, together with their environment. They are the cities of the future.
November 15, 2012 – Consumers are no longer what they used to be. Before they buy, they look around. A lot. And when they buy, they talk about it. To everybody. They want to be treated as unique. They want you to listen to them. They want you to talk to them. They want you to thank them. In short, they are influencers and mini-tyrants who will leave you in the blink of an eye if you don’t do as they please. And that’s the easy part. The problem is that they change so fast that you actually need to know what they want, before they do. Your organization needs to outrun them. It needs to be agile and fast.
