- ▸Processing batch payroll and accounting tasks
- ▸Maintaining enterprise resource planning (ERP) systems
- ▸Handling large-scale transaction processing
- ▸Integrating with mainframe databases like DB2 or IMS
- ▸Reporting and regulatory compliance in finance
Notable Features
- ▸Readable English-like syntax
- ▸Structured programming constructs (PERFORM, IF, EVALUATE)
- ▸File handling and batch processing capabilities
- ▸Database integration via embedded SQL
- ▸Object-oriented features in modern COBOL (OO-COBOL)
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.
