using draw.io Task 3: Design an ER Diagram for a Library Management System (3 Marks)
Scenario: You are tasked with designing a database for a Library Management System. The
system includes books, authors, and library members. Each member can borrow multiple books,
and each book can be borrowed by multiple members. Additionally, each book is associated with
an author. Steps: 1. Identify Entities and Attributes: List the entities involved (Member, Book,
Author) and their respective attributes. 2. Define Relationships: Determine the relationships
between entities. Clarify the type of each relationship (one-to-many, many-to-many, one-to-one).
3. Create an ER Diagram: Using the Mermaid syntax or any other diagramming tool, create an
ER Diagram that visually represents the entities, attributes, and relationships. 4. Label
Relationships: Clearly label each relationship on the diagram, indicating the roles of each entity.
5. Indicate Keys: Highlight the primary keys of each entity. Specify the use of foreign keys
where necessary to establish relationships..
