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, ...

Big data has become a big business, and it will not only shine in the last decade, but it will also become a regular business for companies like enterprise Resource planning, supply chain and customer management, and other parts of the enterprise computing field.

Gartner, the IT market research firm, is holding its Symposium/itxpo conference in Orlando, Florida, and, as in previous years, it has also released some predictions at this year's conference. G ...

In my recent speech, someone once asked me, what mistakes will ultimately lead to the failure of entrepreneurship? When I stood there for a few seconds, I realized that it was a difficult question to answer. Because it's asking: How can a startup succeed. If you can avoid all the mistakes that will lead to failure, you are sure to succeed. 　　So this question is so big that it makes it difficult for me to answer clearly in such a short time. But then I realized that it might make sense to look at it from another perspective. Because if you have a list, in the clear ...

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the distributed features of the NoSQL database ...
