2.2.1 The dimensions of data
dimension ： The organization of a set of data
One-dimensional data ： One dimensional data consists of ordered or unordered data with equal relationships , Organized in a linear way
form ： Corresponding list 、 The concepts of arrays and sets
Lists and arrays ： The ordered structure of a set of data
difference ： list : Data types can be different
Array ： The same type
Two dimensional array ： A two-dimensional array consists of multiple one-dimensional data , It's a combination of one-dimensional data
Multidimensional data ： It is formed by expanding one-dimensional data and two-dimensional data in new dimensions
High dimensional data ： Only the most basic binary relationship is used to show the complex structure of data
