Conceptual Model
A conceptual model is an abstract representation of a system, process, or domain that captures its essential concepts, relationships, and rules in a simplified, high-level form. It serves as a bridge between real-world requirements and technical implementation, often using diagrams, text, or formal notations to communicate understanding among stakeholders. In software development, it helps define what a system should do before detailing how it will be built.
Developers should learn and use conceptual models during the early stages of software design, such as requirements analysis and system architecture planning, to ensure clarity, reduce misunderstandings, and align technical solutions with business needs. They are crucial for complex projects involving multiple teams or domains, as they facilitate communication between developers, product managers, and clients by providing a shared mental model of the problem space.
