The greatest fascination with large data is the new business value that comes from technical analysis and excavation. SQL on Hadoop is a critical direction. CSDN Cloud specifically invited Liang to write this article, to the 7 of the latest technology to do in-depth elaboration. The article is longer, but I believe there must be a harvest. December 5, 2013-6th, "application-driven architecture and technology" as the theme of the seventh session of China Large Data technology conference (DA data Marvell Conference 2013,BDTC 2013) before the meeting, ...

According to a report published last month by IDC (International Data Company), sales of large data technology and services are expected to grow from $3.2 billion trillion in 2010 to $16.9 billion in 2015, with an annual growth rate of 7 times times the average it market. The McKinsey Global Institute points out that data is becoming a factor in products such as physical capital and human capital. Companies that can take advantage of big data will defy the data. Data capital will be as important as brand capital. Business is already adapting to big data, and the data revolution is disrupting already-established industries and business models. No matter ...

Through the introduction of the core Distributed File System HDFS, MapReduce processing process of the Hadoop distributed computing platform, as well as the Data Warehouse tool hive and the distributed database HBase, it covers all the technical cores of the Hadoop distributed platform. Through this stage research summary, from the internal mechanism angle detailed analysis, HDFS, MapReduce, Hbase, Hive is how to run, as well as based on the Hadoop Data Warehouse construction and the distributed database interior concrete realization. If there are deficiencies, follow-up and ...

Large data as a hot word for the web, has been frequently mentioned recently. In fact, global industry giants have been aware of the arrival of the "Big Data Age" by acquiring large data-related vendors for technology integration. 　　Experts say China has the opportunity to lead the development of the cloud computing industry in the "Big Data Age". At the 2012 China Data Center Conference held recently, Ubaogui, Deputy chief engineer of China Institute of Electronic Information Industry development, said that data center as the main support platform for enterprise IT construction, how to effectively and rationally control the total cost of ownership under the premise of the large data to obtain a price ...

Development of cloud computing can not "follow suit" "Cloud flying over" - On the development of cloud computing several issues to be solved So far, China has set off a wave of cloud computing development. From the media's hype, the capital's campaign, to a large number of academic activities co-sponsored business promotion, has been desperate to heat up the concept of cloud computing. Coupled with Google, IBM, Microsoft and other IT giants with unprecedented speed and scale of cloud computing promotion and speculation, it is cloud computing on the peak. Cloud planning, cloud schemata, cloud projects, cloud base seems to have become a government at all levels ...

1, the existence of a huge leap in the background infrastructure, data storage technology, network technology, the rapid development of the era of large data to prepare the material base. The Internet of Things is essentially more portals and nodes of data acquisition, and cloud computing fosters the business model of service and centralized construction to reduce unit computing and storage costs. The mobile internet is even more interesting: the first feature is the identity, at the right time, the right place, the right information to the right person, you need to know who your partner is, what he likes, he is now what state, no such accurate identity information, everything ...
