A Brief History of Data

Abstract

The earliest collections of computerized data began with wired boards, paper tape, and punched cards. Then magnetic tapes came quickly followed by disk storage. After disk storage came data base management systems, followed by online high-performance transaction systems. Then came 4GL technology, the personal computer, and spreadsheets. The first processors were uniprocessors. Then came tightly coupled multiplexed processors. Parallel processors came next, leading to Big Data. With data base management systems came data warehouses, where there was “a single version of the truth.” After data warehouse came data vault.
