database
English
“A database is a structured collection of data — and the concept that data should be organized by its relationships rather than by the programs that use it is a 1960s idea that now underlies every digital service on earth.”
The compound word database — data + base — appeared in computing contexts in the early 1960s, first in US military computing discussions and then in academic papers. Data came from Latin datum (given thing, plural data, things given); base from Latin basis (foundation). A database was the foundation of given information — not just a collection of data but an organized, structured foundation from which programs could extract what they needed.
Charles Bachman built the first proper database management system, IDS (Integrated Data Store), at General Electric in 1963. His system organized data in a network structure that allowed multiple programs to access the same data without redundancy. Before IDS, each program stored its own data — the same customer address might be stored separately in accounts payable, shipping, and customer service. Bachman's insight: store the data once, let programs access it by query.
Edgar Codd, working at IBM in 1970, published 'A Relational Model of Data for Large Shared Data Banks' — the paper that became the foundation of all modern databases. Codd proposed organizing data in tables (relations) where rows and columns had strict definitions, and queries could combine tables through set operations. His relational model resisted the arbitrary structures of Bachman's network approach and provided mathematical foundations for data manipulation.
The relational database system (RDBMS) — Oracle, founded 1977; IBM DB2; later MySQL, PostgreSQL — became the infrastructure of the internet. Every website, every app, every transaction, every login is backed by a database. Larry Ellison built Oracle into a $300 billion company on Codd's 1970 mathematical paper. The foundation of given information became the foundation of the digital economy.

Codd's 1970 paper was written in mathematical set theory. Most IBM managers ignored it as too theoretical. Larry Ellison read it and founded Oracle. The relational database became the infrastructure of capitalism: every financial transaction, every customer record, every product inventory runs on the tables-and-queries model Codd described with mathematical precision.
The database is what allows the same data to be asked different questions. It is not a filing cabinet — it is a system of relationships. The same customer can appear as a debtor in accounts receivable, a buyer in sales, and an address in shipping, all from one stored record. Data once; accessed many times, in any direction.
