Z notation

Z notation is a formal language used in computer science to precisely specify and describe the structure and behavior of software systems. It uses mathematical symbols and logic to create clear, unambiguous models of how data is organized and how processes operate. This helps in designing, analyzing, and verifying systems rigorously, reducing errors and misunderstandings. Essentially, Z notation provides a structured way to document system requirements and ensure accuracy through mathematical clarity, which is especially valuable for complex or safety-critical applications.
