Task 2: Design an ER Diagram for a Music Streaming Service (3 Marks) Scenario: You have
been assigned to design a database for a Music Streaming Service. Users can create playlists
containing multiple songs, and each song can belong to multiple playlists. Additionally, each
song has an associated artist. Steps: 1. Identify Entities and Attributes: List the entities involved
(User, Song, Playlist, Artist) 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.
