dataset
data collection / data set / information repository
Noun
pl: datasets
This term describes a curated collection of information designed for systematic analysis. It carries a strong connotation of structure and purpose, implying that the data is not random but has been gathered or organized to answer a specific question or train a specific algorithm. In technical contexts, it often refers to the division of data into training, validation, and test sets. While it functions as a standard countable noun, it is frequently used in the singular to describe a single, massive repository of information regardless of the number of individual records it contains.
