Introduction
This proposal supports business agility by leveraging COBOL’s structured yet adaptable nature, implemented through model-driven architecture, to quickly transform business requirements into executable code as a digital business process.
COBOL is not a legacy system; it’s an evolving legend capable of driving the requirements of the modern digital world while maintaining its elegance. COBOL continues to evolve and remains highly relevant, especially in critical systems like finance and government. Its robustness and adaptability have allowed it to meet modern digital requirements while preserving its original strengths.
Common Business-Oriented Language (COBOL)
Well deserving its name, Common Business-Oriented Language (COBOL) is a high-level programming language with keywords and statements that are very close to human language, making it unique for its focus on being easily understood by non-technical users.
COBOL’s four divisions provide a structured way to organize code that aligns well with business processes. Each division serves a specific purpose, making it easier to map business contexts into a digital format.
The 2023 ISO Standard for the COBOL programming language highlights its enduring relevance and adaptability, reinforcing its legendary status in supporting both legacy systems and modern digital needs.
COBOL’s Modern-Day Relevance and Applications
Despite being over six decades old, COBOL’s longevity is a testament to its efficiency and reliability. The language is deeply embedded in mission-critical systems that underpin global industries. Over 80% of in-person transactions at ATMs, bank branches, and point-of-sale systems rely on COBOL-based infrastructure. The world’s financial institutions, governments, and even airlines continue to utilize COBOL to process vast amounts of data and ensure seamless operations.
Extending COBOL’s Reach with IBM Rational Modeling Tools
IBM’s Rational modeling tools are already renowned for automating code generation from visual models, allowing businesses to significantly reduce time-to-market for new applications. Extending these tools to generate COBOL could introduce unprecedented efficiencies, especially in sectors like retail, healthcare, and logistics where large-scale, data-heavy applications dominate. This kind of innovation would enable even non-technical business stakeholders to participate in the system’s design, ensuring the final product aligns precisely with business goals and operations.
Applying model-driven COBOL architecture in the retail sector could revolutionize both business and economic landscapes. It would streamline operations, enhance data processing, and improve decision-making efficiency, driving substantial transformation in retail’s digital ecosystem.
COBOL’s Future in the Digital Economy
As digital transformation accelerates across industries, the need for reliable, scalable, and adaptable software infrastructure is more critical than ever. COBOL’s proven track record positions it as an ideal candidate to meet these demands. Its continued development, with advancements like the 2023 ISO Standard, demonstrates COBOL’s ability to integrate with modern technologies, including cloud computing, artificial intelligence, and big data analytics.
COBOL-based Digital Businesses
COBOL has great potential to be used for initiating and running digital businesses if IBM extends its Rational modeling tools to generate COBOL. This could streamline development for digital businesses by bridging model-driven architecture and COBOL’s strengths in handling large-scale business applications.
Generating COBOL means framing a digital business. For example, the COBOL Data Division will maintain business information, from reading data from IoT devices to supporting business decisions with context-specific reports.
Model-driven architecture, in simple terms, is the process of transforming the business language of requirements into a visual model, which is then converted into application code.
What entrepreneurs need to focus on is identifying business requirements and defining their intended business model. The modeling tool generates a visual model, which serves two purposes: on one hand, it facilitates communication about the business model among all interested parties, and on the other hand, it generates COBOL as a business shell ready for launch. All that’s needed afterward is an IBM COBOL Runtime Environment on z/OS, LinuxONE, or AIX to run the generated COBOL, effectively operating the business in a digital space.
The running COBOL system can indeed include interfaces for external communication, allowing regulators to receive real-time reports and ensure compliance based on accurate data. These interfaces would also enable continuous monitoring for stakeholders, ensuring alignment between the original business model and live operations, maintaining transparency and consistency throughout the business lifecycle.
Model-driven COBOL and Business Agility
This proposal supports business agility by leveraging COBOL’s structured yet adaptable nature, implemented through model-driven architecture, to quickly transform business requirements into executable code as a digital business process. By automating the code generation process from visual models, businesses can rapidly adapt to changing market demands, streamline operations, and iterate on business models with minimal delays, ensuring responsiveness and flexibility—key aspects of an agile approach.
The Role of COBOL in Industry-Specific Transformations
Industries like banking, insurance, and public sector governance rely heavily on COBOL for backend processes that are invisible to most end-users but are integral to ensuring business continuity. In retail, a sector undergoing rapid digital transformation, COBOL could serve as the foundation for modern customer management systems, inventory tracking, and supply chain operations. In this context, COBOL’s ability to process large datasets efficiently would enable real-time decision-making, improved customer experiences, and operational efficiency.
The modern digital business landscape requires not only innovation but also trust in the systems that form its foundation. COBOL, with its combination of reliability, adaptability, and clarity, continues to meet these requirements, making it an essential tool in driving digital business transformation.
