Index

Definition

An index is a data structure that enhances the speed of data retrieval operations on a database or spreadsheet by providing a quick reference to the actual data. In the context of spreadsheet-based analytics, indices can refer to row and column labels that allow users to efficiently locate and analyze information within large datasets, making data management and analysis more streamlined.
