Today's IT World, database NoSQL and newsql processing data way, has gone beyond the use of traditional relational databases. Traditional relational databases don't disappear forever--but their brilliance has passed. Many of the NoSQL databases that have just come out have become popular, such as Mongndb and Cassandra. This is a good remedy for the limitations of the traditional database system. Of course, relative to the rapid development of NoSQL, the database system based on SQL is rather lifeless. This should be the database needs constant Progress update ...

It has been almost 2 years since the big data was exposed and the customers outside the Internet were talking about big data. It's time to sort out some of the feelings and share some of the puzzles that I've seen in the domestic big data application. Clouds and large data should be the hottest two topics in the IT fry in recent years. In my opinion, the difference between the two is that the cloud is to make a new bottle, to fill the old wine, the big data is to find the right bottle, brew new wine. The cloud is, in the final analysis, a fundamental architectural revolution. The original use of the physical server, in the cloud into a variety of virtual servers in the form of delivery, thus computing, storage, network resources ...

The first cloud storage standard--Cloud data Management Interface (CDMI)--was unveiled at the SNW Spring Festival Convention on April 12, 2010 at the official website of the American Network Storage Industry Association (SNIA). The birth of the first ever cloud storage standard, it was born, without a doubt, that the storage vendors and business users are excited by the expectation that cloud storage will solve the current storage dilemma. Before, SNIa to avoid the confusion of end users, the industry is too dispersed and some related losses of market growth power, as early as 2009 years in half ...

We have all heard the following predictions: By 2020, the amount of data stored electronically in the world will reach 35ZB, which is 40 times times the world's reserves in 2009. At the end of 2010, according to IDC, global data volumes have reached 1.2 million PB, or 1.2ZB. If you burn the data on a DVD, you can stack the DVDs from the Earth to the moon and back (about 240,000 miles one way). For those who are apt to worry about the sky, such a large number may be unknown, indicating the coming of the end of the world. To ...

For large companies, the rise in large data is partly because computing power is available at lower cost, and systems are now capable of multitasking. Second, the cost of memory is also plummeting, and businesses can handle more data in memory than ever before. And it's getting easier to aggregate computers into server clusters. 　　Carl Olofson, IDC's database management analyst, believes the combination of these three factors has spawned big data. "Not only do we do these things well, but we can do them at a lower cost," he said. "There used to be ...

A news incident last week attracted media attention, with nearly 450,000 passwords from 450,000 yahoo services called ' Yahoo Voice ' hacked. The comment on the incident said that hackers mainly through SQL injection (SQL injection) technology is the hacker from the database to obtain information and then release the information of the main technology adopted. Even if the original article is modified, you can find the error if you do a check. Technology is the same, as every more in-depth discussion can find new problems. ...

The big data age has come and has quietly influenced our lives. According to a recent study by IDC, 1 million new links are shared every 20 minutes on Facebook and 10 million user reviews are released. 　　Facebook and all other Internet sites, Internet applications, have gradually become the entire data collection, analysis, processing and value-added architecture. In China, social networks are also in full swing. Sina Vice President Wang Gaofei has said that Sina Weibo has registered more than 300 million users, users on average daily release more than 100 million micro bonnet ...

Today, IBM, one of the three major manufacturers of traditional database fields, announces that it will add NoSQL functionality to future DB2 flagship databases. And just yesterday, database leader Oracle announced the release of its latest NoSQL database, although the two products are intrinsically different (Oracle NoSQL Datbase will be released as a stand-alone product, based on Berkeley DB IBM's NoSQL database will migrate to DB2 and Informix, with no specific technical details to release. )...

The development of spark for a platform with considerable technical threshold and complexity, spark from the birth to the formal version of the maturity, the experience of such a short period of time, let people feel surprised. Spark was born in Amplab, Berkeley, in 2009, at the beginning of a research project at the University of Berkeley. 　　It was officially open source in 2010, and in 2013 became the Aparch Fund project, and in 2014 became the Aparch Fund's top project, the process less than five years time. Since spark from the University of Berkeley, make it ...

"The key is not in what methods, but in being able to really solve problems using any available tool or method," said Forrester analyst James Kobielus in a blog about Big data. "In recent years, with the urgent sense of solving big data problems, many organizations have started to explore the data architects." 　　In short, traditional databases and business intelligence tools that they typically use to analyze enterprise data are no longer competent for large data-processing tasks. To understand this challenge, we must go back to 10 years ago: There were very few t ...
