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.
In an industrial or manufacturing context, "data" refers to the raw information or facts that are collected, analyzed, and used to make decisions, improve processes, and optimize operations. Data can be in the form of numbers, text, images, or other forms of digital or analog information.
