7. 数据
• Data are values of qualitative or quantitative variables, belonging to a set of items.
Data in computing (or data processing) are represented in a structure, often tabular
(represented by rows and columns), a tree (a set of nodes with parent-children
relationship) or a graph structure (a set of interconnected nodes). Data are typically
the results of measurements and can be visualised using graphs or images. Data as
an abstract concept can be viewed as the lowest level of abstraction from which
information and then knowledge are derived. -------维基百科
