Over the past three years, the Hadoop ecosystem has expanded to a large extent, with many major IT vendors introducing Hadoop connectors to enhance the top tier of Hadoop or the Hadoop release that the vendor uses. 　　Given the exponential growth in the deployment rate of Hadoop and the growing depth and breadth of its ecosystems, we wonder whether the rise of Hadoop will lead to the end of traditional data warehousing solutions. We can also put this issue in a larger context to discuss: to what extent, large data will change ...

After MySQL was acquired by Oracle, the industry has never stopped talking about the Open-source database, and the voice of PostgreSQL will be replaced as the most popular Open-source database. However, from the Db-engines rankings, the gap between PostgreSQL and MySQL is far more than "a few floors" so high (PostgreSQL not score a fraction of MySQL). Looking at the entire list of 193 databases, we will find that the NoSQL database has accounted for most of the traditional relationship ...

The use of Hadoop has been going on for some time, from the beginning of confusion, to various attempts, to the current combination of .... Slowly involved in data processing things, has been inseparable from Hadoop. The success of Hadoop in large data fields has led to its own accelerated development. 　　Now the Hadoop family product, has already reached 20 many. It is necessary to do a collation of their knowledge, the product and technology are strung together. 　　Not only can deepen the impression, but also to the future technology direction, technical selection to do the groundwork. A word product introduction: ...

After the arrogant data has entered the people's view, it gradually becomes the focus that people pay attention to generally. Large data is the PB era of science, in essence, the challenge of large data is the PB era of science challenges, but also the cognitive science including data mining challenges. 　　So what about data mining in the big data age? In modern times, people often say that large data mainly includes three sources: the first is the large data of nature, the natural environment on Earth, very big. The second is the big data of life. The third and most important is the social data that people care about. These data are common ...

March 25, 2014 Tuesday, csdn online Training "application of hbase in Millet" will meet you! HBase is a distributed, column-oriented open source database that comes from a Google paper written by Chang et al, "Bigtable: a distributed storage system with structured data". Like Bigtable, Google file system System), like the distributed data storage provided by HBase, the ...

While Microsoft has not yet made clear how to incorporate Windows Azure pricing into corporate customers who have signed a long-term contract with the company, Microsoft executives say Microsoft intends to make it easier for these customers to take advantage of Microsoft's new cloud computing services as soon as this week. At Microsoft's Global partners conference last week, Microsoft said Azure would be officially commercially available in November and would set a price policy for cloud-based applications and development platforms. Microsoft also said that Azure would be part of Microsoft's product package through volume licensing contracts ...

In the current enterprise IT architecture, system administrators and DBAs will consider using the NoSQL database to solve problems that the RDBMS cannot solve, especially the internet industry. Traditional relational databases store data mainly as tables (table), and cannot meet the challenge of unstructured data. In the process of data standardization, the performance of relational database is encountering bottleneck. NoSQL, as its name suggests, is Not-only SQL, which can be a good complement to relational databases. In the report before the TechTarget database, ...

Research on the construction of medical and health data center based on HBase and the synchronization of heterogeneous database Fang Shiwei to determine the data model, this paper puts forward the idea of HBase C-o-r modeling based on the E-R modeling of relational database, Then comprehensive analysis of Health department promulgated medical and Health metadata standards and the actual situation of some health institutions to achieve health information HBase Data Center construction. In order to realize the synchronization of data transparently to data center in heterogeneous relational database of medical institutions, the following schemes are proposed. First of all, in the data format proposed heterogeneous database production ...

In the 2009, Aliyun began to develop independently. Over the past six years, Aliyun's contribution to the development of China's cloud computing industry is obvious. "Amazon Cloud computing is no doubt important to the development of the entire new industry globally," Liu, the csdn& editor of the programmer, said. For China, the success or failure of Aliyun has a similar weight. Lei, who just advertised 1 billion dollars to build Jin Shanyun, said: "From the beginning of the Amazon to the Aliyun, a layer of preheating, I think now cloud computing is getting better." "To appreciate the ecological changes in China's cloud computing, ...

Distributed Deployment architecture: implementation of the application of loose coupling, will Web application server and caching, database services and other modules decoupling, and physically isolated deployment, so that the level of functional modules can be extended, but also to avoid the cloud server IO scramble to bring about the performance degradation problem. Eliminate the single point of deployment: More than one login server, the back-end game area deployed more than one, all provide the same service; both are configured load balanced sharing flow, to avoid single point of failure. Game Update Service: can be based on Aliyun OSS+CDN provide static file distribution of low latency, if the game has a lot of ...

It is easy to compare the cost of cloud computing vendors, but it is not easy to compare the performance of the application. A performance comparison of the different types of database applications running in the same cloud or across different cloud computing environments will be a particularly challenging task. The Yahoo Cloud computing Service Benchmark (YCSB) is a test framework designed to help users understand the performance of different cloud computing databases and store data performance under actual load. The source code for this test framework is available from the GitHub download. Yahoo cloud services benchmark tools include ...

2010 should be remembered because SQL will die this year. This year, the relational database is on the verge of falling, and this year developers found they no longer needed long, laborious columns or tables to store data. 2010 will be the starting year for document databases. Although this momentum has lasted for many years, it is now the era of more and broader document-based databases. From cloud-based Amazon to Google, a large number of open source tools, and the ensuing CouchDB and MongoDB. So what is MongoD ...

The difference between the MONGO DB and SQL Serv-er 2000 in the storage and concurrent access performance of the NoSQL database products oriented to document is analyzed by experiment. The results show that the Mongo db in the mass space number ...

The development of any new technology will undergo a process from the public to the final universal application. Large data technology as a new data processing technology, after nearly a decade of development, has just begun to be applied in various industries. But from the media and public view, the big data technology always has the mysterious color, appears to have the magical power which digs the wealth and forecasts the future. Widely circulated large data applications include the target supermarket based on the girl's shopping history to determine whether pregnancy, credit card companies based on the user in different time and space shopping behavior to predict the customer's next purchase behavior, and so on. Large Data Technology ...

Forbes: hadoop--Big Data tools you have to understand now Apache Hadoop has become the driving force behind the development of the big data industry. Techniques such as hive and pig are often mentioned, but they all have functions and why they need strange names (such as Oozie,zookeeper, Flume). Hadoop has brought in cheap processing of large data (large data volumes are usually 10-100GB or more, with a variety of data types, including structured, unstructured, etc.) capabilities. But this is the same as before ...
