Course IntroductionR is a language and operating environment for statistical analysis, mapping, a free, free, open source software for the GNU system, an excellent tool for statistical computing and statistical mapping.The R language grammar is easy to understand and can easily learn and master the grammar of language. And after learning, we can develop our own functions to extend the existing language. This is why it is much faster to update than the general statistical software, such as SPSS,

SqlSever Big Data paging and SqlSever data Paging
In SQL Server, the paging of big data has always been a hard part to be processed, and the use of id auto-incrementing column paging also has shortcomings. From a relatively comprehensive page view, the row_number () function

In addition, Varchar,text,date,time,enum and other types of data also require single-quote decoration, while int,float,double
Essential Python Lib
This section describes various types of libraries commonly used by Python for big data analysis.
Numpy Python-specific standard module library for numerical computation, including:
1. A powerful n-dimensional Array object Array;
2. Mature (broadcast) function libraries;
3. toolkit for integrating C/C ++ and Fortran code;
4. Practical linear algebra, Fourier transformation, and ran

In order to avoid unnecessary trouble. Some of the data is not very clear, the key to see the point of thinking.Through statistical analysis of big data, I found that a linear formula can be used to perfectly fit a user conversion link. Based on this formula, we make predictions about the data that haven't occurred rec

For a long time, large data communities have generally recognized the inadequacy of batch data processing. Many applications have an urgent need for real-time query and streaming processing. In recent years, driven by this idea, a series of solutions have been spawned, with Twitter Storm,yahoo S4,cloudera Impala,apache Spark and Apache Tez to join the big
