Maintainable Mike Bowers - From ISAM to JSON—Navigating 40+ Years of Database Evolution
Mike Bowers, Chief Architect at FairCom, has spent decades navigating the evolution of database technology. In this conversation, he and Robby explore the challenges of maintaining a 40+ year-old codebase, balancing legacy constraints with forward-thinking design, and the realities of technical debt.
Mike shares how FairCom transitioned from ISAM-based databases to modern JSON-driven APIs, the trade-offs between strict schemas and flexible document stores, and how software architecture plays a critical role in long-term maintainability. He also explains why human-readable JSON simplifies debugging, how documentation-driven development improves API usability, and why many software teams struggle with refactoring at the right time.
