COBOL in Everyday Life: Why Are We Still Fascinated by This Old Language? (Expanded Version)

  1. Introduction (50 words)


    The old saying "the elderly are wiser than we believe" holds true in the IT sector, and COBOL, a programming language developed in the 1950s, is a testament to this. With its daily presence, it continues to challenge our assumptions about what counts as obsolete.

  2. History of COBOL (100 words)
    COBOL – Common Business-Oriented Language – was born in response to the commercial sector’s demands. Its earliest applications were found in banks and insurance companies, where it continues to thrive today. Developed by a team led by Grace Hopper, COBOL aimed for readability and maintainability.

  3. Why COBOL Still Lives (125 words)
    COBOL is not just old but also resilient. Its applications can handle large data volumes, and their stability makes them almost impervious to change. The IT industry has long tried to replace COBOL but has discovered several reasons for its persistence.

    These include:

    • Ease of Use: COBOL’s syntax is straightforward, making it easier for new developers to learn.
    • Robustness: Its applications can run without interruption, which is crucial in sectors like finance and healthcare where downtime can be costly.
    • Compatibility: Many systems still rely on legacy COBOL code, which would require a significant investment to replace.

  4. COBOL vs Modern Programming Languages (100 words)
    How does COBOL stack up against modern programming languages?

    Let’s compare their syntax, performance, and application areas:

    • Syntax: COBOL has a simple, structured syntax that makes it easier to read and write. In contrast, modern languages offer more complex functionalities and flexible syntaxes.
    • Performance: COBOL excels in processing large data sets quickly. Modern languages often focus on memory management and multitasking capabilities.
    • Application Areas: COBOL is predominantly used in industries like finance, insurance, healthcare, and public administration, where stability and compatibility are essential. Modern languages cater to various sectors, from web development to artificial intelligence.

  5. Example: The Bank Replacing the Old (100 words)
    A real-life case study shows us that COBOL remains a vital component in today’s economically successful banks. For instance, Deutsche Bank reportedly relies on over 300 legacy systems written in COBOL for its core banking operations. This dependence demonstrates the language’s continued relevance and importance.

  6. Perspectives and Outlook (75 words)
    COBOL is neither old nor obsolete. It forms a crucial part of the IT landscape, and its future development indicates that it will continue to live on. What excites us most about COBOL is its potential to make tomorrow better than today – by enhancing existing applications or integrating with modern technologies like cloud services and artificial intelligence.
