Big Data Rdbms

There are two main ways to store data: Database and filesystem, and the object-oriented storage are developed behind, but the overall thing is to store both structured and unstructured data. DB is initially serviced for structured data storage and sharing. FileSystem storage and sharing is large files, unstructured data, such as pictures, documents, audio and video. With the increase in data volume, stand-alone storage can not meet the needs of structured and unstructured data, then in the era of cloud computing, there is a distributed ...

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 ...

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 ...

When Guoda, the data is big also should find a destination. Some people say that big data is the apple of cloud computing, the place of the princess. Although the emperor's daughter does not worry about marrying, but the big data is not as good as the virtual Lori best-selling, everyone in hot discussion big data, once want to talk about marriage, many people seem to have a marriage phobia. Do not doubt the big data is not enough charm, because the big data although it makes people's imagination, but the big data of the wedding night full of suspicious. Just the past 2012 is really big data of the year, the matchmaker seems to have broken the threshold of each data center, everyone on the big data ...

Traditional data storage and management are based on structured data, so relational database systems (RDBMS) can meet the needs of various applications.

(Author Srini penchikala translator Dingxuefeng) for non-relational data types such as documents, object graphs, and key-value pairs, the NoSQL database provides them with an alternative way to store data. Can distributed caching be used as a NoSQL database? Ehcache's Greg Luck author describes the similarity between distributed caching and NoSQL databases. Infoq interviewed him and discussed the pros and cons of the scheme. InfoQ: Can you do a distributed caching solution with the NoSQL database ...

Storing them is a good choice when you need to work with a lot of data. An incredible discovery or future prediction will not come from unused data. Big data is a complex monster. Writing complex MapReduce programs in the Java programming language takes a lot of time, good resources and expertise, which is what most businesses don't have. 　　This is why building a database with tools such as Hive on Hadoop can be a powerful solution. Peter J Jamack is a ...

Whether the cloud-computing tide has receded for the time being, and the latest survey by Gartner, a research institute, shows that the cloud computing sector will keep growing, and growth will slow, after all, cloud computing has been a lot of trouble. Now, a new concept that is not clearly defined as cloud computing is increasingly popular-"big data". And big data has begun to change the IT landscape, according to Gartner data, only 2012 years of large data to drive the world's 28 billion of dollars in IT spending, 2013-led IT spending scale is expected to enter ...
