Z specification

The Z specification is a formal method used in computing and software engineering to describe and model systems mathematically. It uses mathematical notation to specify the structure and behavior of software and systems precisely. By capturing requirements and design in a clear, unambiguous way, Z helps ensure that a system meets its intended purpose and can be correctly developed and verified. It represents data types and operations through sets and relations, making it easier to reason about complex software systems and identify potential issues early in the development process.
