Python's Best object-relational mapping tool is sqlobject--an open source project that almost completes all the operations required by the programming database. This article introduces SQLObject and its functions. After reading this article ...

Hadoop MapReduce is a programming model for data processing that is simple but powerful enough to be designed for parallel processing of big data.

In the 8 years of Hadoop development, we've seen a "wave of usage"-generations of users using Hadoop at the same time and in a similar environment. Every user who uses Hadoop in data processing faces a similar challenge, either forced to work together or simply isolated in order to get everything working. 　　Then we'll talk about these customers and see how different they are. No. 0 Generation-fire This is the beginning: On the basis of Google's 2000-year research paper, some believers have laid down the ability to store and compute cheaply ...

HBase is a distributed, column-oriented, open source database based on Google's article "Bigtable: A Distributed Storage System for Structured Data" by Fay Chang. Just as Bigtable takes advantage of the distributed data storage provided by Google's File System, HBase provides Bigtable-like capabilities over Hadoop. HBase Implements Bigtable Papers on Columns ...

At present, what is cloud computing, what kind of platform belongs to the cloud computing platform, and so on cloud computing related issues, different hardware and software manufacturers have their own different understanding, have their own different definitions. The cloud computing platform they offer is also vastly different. When it comes to cloud computing, people always think of these things: high scalability (scalability), cost savings (saving), on-demand (use on Demand), and so on. Let's give it a few of the myriad things that cloud computing brings ...

"Cloud computing" estimates that in our interactive television industry, not many people will notice in the recent internet IT industry quietly emerging from a new term "cloud computing."     And the "cloud computing" business applications, but began to flood our modern society, and slowly affect our lives, and even change our user experience and habits (can actually see, feel is ready to sell in 09 cheap Internet notebook).
