Origin & Creator
Developed in 1959 by a consortium including CODASYL and led by Grace Hopper to provide a standardized business programming language.
Industrial Note
Extensively used in banking, insurance, government payroll systems, and mainframe applications where decades-old COBOL systems still operate mission-critical workloads.
