In the context of computer science and information systems, a conceptual schema is a conceptual model that defines the structure, behavior, and constraints of a database system or similar data management system. It describes the entities, attributes, and relationships within the system, providing a high-level view of how the data is organized and accessed.
A conceptual schema acts as an intermediary between the user's understanding of a domain and the actual implementation of that domain in a specific technology or system. It abstracts away the technical details and focuses on representing the essential elements and concepts of the domain.
By using a conceptual schema, designers and developers can ensure that the system accurately represents the desired functionalities and requirements. It serves as a guide throughout the system development lifecycle, assisting in the design, implementation, and maintenance of the system.
In summary, a conceptual schema is a structured representation that captures the fundamental concepts, relationships, and rules of a domain or system. It provides a high-level view of the system's structure and behavior, facilitating efficient communication, analysis, and design.
