Data visualization is the most challenging and challenging part of data analytics, but its importance does not allow us to question it. In fact, visualization is definitely one of the most important parts of analytical data analytics. Of course, storage, database query processing and algorithms are all very important. And without them visualization is impossible. But in a data-driven world, they are just at the base level. Here are six startups who are trying to radically change the visualization of their data. Some of them are highly complex visual processes, some are not. Although none of them is perfect ...

MapReduce is a high-performance batch processing distributed computing framework for parallel analysis and processing of massive data. Compared with traditional data warehousing and analysis techniques, MapReduce is suitable for dealing with various types of data, including structured, semi-structured, and unstructured data. The data is at terabytes and PB levels, and at this level, traditional methods are often unable to process data. MapReduce divides the analysis task into two categories: a large number of parallel Map tasks and a Reduce rollup task. Map task runs in multiple suits ...
