Domain Modeling Basics: Building Smart Calculators for Humans and AI

Translating real-world logic into clean code can be challenging, especially when dealing with calculations involving dates, ranges, and physical measurements. To build software that is easy to maintain—and easy for AI assistants to help you write—you need a solid foundation in domain modeling. In this written course, you will learn how to design clear, structured data models that define how your application handles complex logic. By practicing with real-world scenarios like date-and-temperature calculators, you will gain the skills to write self-documenting code that both human teams and AI coding tools can understand instantly. What you'll learn: Understand the core principles of domain modeling and structured data design; Create robust data structures using modern type hints and clean schemas; Model complex calculation logic involving dates, ranges, and temperature data; Debug and refine domain models to prevent logical errors and edge cases; Format your code and documentation to optimize collaboration with AI coding assistants. You will start by exploring foundational modeling concepts and defining simple domain boundaries. From there, you will progress to building a practical calculation model, testing your logic through written code walkthroughs, and learning how to structure your code for modern development workflows. This course is designed for beginner developers, software designers, and tech enthusiasts looking to improve their system design skills. No advanced programming experience is required.
