Database
Etymology
A compound of "data" and "base," coined in the 1960s as computers moved from processing one file at a time to managing shared pools of structured information. The "base" evokes a foundation on which applications are built. The key advance it names is organization: not just storing data, but arranging it so relationships can be queried and kept consistent.
noun · /DAY-tuh-bayss/
An organized store of information structured so it can be searched, updated, and cross-referenced quickly.
What it names
The backbone behind almost every app and institution — the reason a search returns in milliseconds and your records stay consistent.
Example
A single misplaced entry in the database billed thousands of customers twice.
Related idea
A database is structured for querying and relationships, unlike a plain file, which just holds contents — the difference between a searchable, cross-linked library catalog and a heap of loose documents.
