COBOL Software Development Practices and Methodologies

Maintaining and evolving business-critical systems requires more than just knowing how to write syntax. This course provides a comprehensive understanding of how COBOL applications are developed, tested, and managed in enterprise environments, bridging the gap between legacy code and modern engineering standards. You will gain the skills necessary to navigate complex software lifecycles and ensure the long-term stability of mainframe applications. Through this text-based program, you will learn to: * Understand the principles of self-documenting code and technical documentation standards. * Practice strategies for reading, analyzing, and safely updating existing legacy codebases. * Apply quality assurance (QA) methodologies and modern testing patterns to COBOL development. * Learn how technical support and incident management function within large-scale enterprise systems. * Explore project management frameworks and modern CI/CD integration for mainframe environments. * Master the fundamentals of version control and collaborative development in a professional setting. The course begins with foundational concepts of software architecture and key terminology before moving into practical maintenance strategies, quality standards, and the lifecycle of enterprise applications. It is designed specifically for beginners and aspiring developers who want to understand the professional landscape of mainframe software engineering with no prior experience required.
