Give 1 example for conceptnal model
Answer (1)
A conceptual model helps us understand a system by representing its key concepts and their relationships, often in a simplified way.Here's an example:Conceptual Model of a Library SystemImagine you're designing a new digital library system. Before you start coding or even drawing detailed diagrams, you might create a conceptual model to understand the core elements and how they interact.Key Concepts: * Book: Has properties like Title, Author, ISBN, Publication Date, Genre. * User: Has properties like Name, User ID, Contact Information, Membership Status. * Borrowing: An action or relationship representing a User taking out a Book. * Return: An action or relationship representing a User bringing back a Book. * Librarian: A type of User with additional privileges (e.g., managing books, managing users).Relationships: * A User can Borrow multiple Books. * A Book can be Borrowed by multiple Users (though not at the same time). * A Librarian can Add new Books to the system. * A Librarian can Manage Users.How it works as a conceptual model:This is a conceptual model because it focuses on: * High-level ideas: It doesn't specify database tables, programming languages, or user interface elements. * Core entities and their interactions: It identifies the fundamental "things" in the system (books, users) and how they relate (borrowing, returning). * Understanding and communication: It provides a common language for stakeholders (developers, librarians, users) to discuss the system's purpose and functionality.It helps to answer questions like: "What are the main things we need to keep track of?" and "How do people interact with these things?" without getting bogged down in implementation details.
