Data visualization technology can help people to understand the large amount of data information and discover the laws hidden in the data, so as to improve the efficiency of the data using the visual thinking ability of the human brain. In the face of big Data's profundity,

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,

In addition, Varchar,text,date,time,enum and other types of data also require single-quote decoration, while int,float,double

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

Netflix recently open source a tool called Suro, which the company can use to do real-time orientation of the data source host to the target host. Not only does it play an important role in Netflix's data pipeline, but it's also impressive for large-scale applications.Netflix's various applications generate tens of billions of of events per day, Suro can be collected before

A few are retained because MySQL needs them and (currently) uses the YACC parser. Reserved words can be used as identifiers when they are caused.MySQL allows some of the keywords to be used as unrecognized identifiers, because many people have been using them before. Some examples are listed below: ACTION BIT DATE Enum NO TEXT Time TIMES
