Choose a good data analysis tool, you must understand the analysis of what data, big data to analyze the data types are mainly four categories:1 , transaction data (TRANSACTION)The Big data platform is able to capture a larger and larger amount of structured transaction data, so that more extensive transaction data types can be analyzed, not just pos or ecommerce shopping data, but also behavioral transacti

current scope. This is why big data is defined in 4 ways: Volume (volume), Variety (variety), Velocity (efficiency), and veracity (value), or 4V of big data. The following outlines each feature and the challenges it faces: 1. Volume Volume is talking about the amount of data a business has to capture, store, and access, producing 90% of all the world's data in just the last two years. Today's institutions are completely overwhelmed by the volume of data, easily producing terabytes or even petab

For successful data analysis, it is very important to grasp the nature of data as a whole, and to use statistics to examine the characteristics of data, mainly to check the degree of concentration, degree of dispersion and distribution shape of the data, which can be used to identify some important properties of the whole data set, and has a great reference for the subsequent data analysis. one, basic stat
