表格处理概述
Tabular data is data structured like a two-dimensional table, with each column of data representing a variable and being of the same type, such as numbers or dates, and each row representing a measurement of all the column variables. Tabular data is ubiquitous, such as in relational and multidimensional databases, spreadsheets and tabular data formats. Tabular data is easy to transform, visualize and model for insights. The Wolfram Language provides state-of-art functionality for tabular processing, from access to data sources, data cleaning to transforming, visualizing and modeling to gain insights to communicating the results for actions.
