This is true in academia, where the "real professor" decides the details, leaving only the "things in the direction". In other words, the organization faces vertical collaboration: Top managers manage some (cheaper) employees in a parallel structure. In research institutions, senior scientists put forward ideas, and the task of junior scientists is to achieve these ideas. Over time, advanced science ...

Therefore, the basic structure of the data warehouse mainly contains the data inflow and outflow process, can be divided into three layers-source data ...

MapReduce is a distributed programming model developed by Google for mass data processing in large-scale groups. It implements two functions: map applies a function to all members of the collection, and then returns a result set based on this processing. and reduce is the classification and generalization of result sets that are processed in parallel by multiple threads, processes, or stand-alone systems from two or more maps. The Map () and Reduce () two functions may run in parallel, even if not in the same system ...
