Students have asked these similar questions
Draw an Entity Relationship Diagram of Store Management System(Retail Store Database). Properly mention the entities, identify the relationships and find the cardinality of each relation very carefully. At this point of time your ERD should be final and not any major changes should occur.
Properly mention following:
a. Entity
b. Relationship
c. Attributes
d. Cardinality
iF HAND WRITTEN THE DIAGRAM SHOULD BE NEAT
DO NOT POST COPIED DIAGRAM
Please, can you DRAW the NEW ER diagram to comply with the new requirements requested, and also indicate what type of cardinality each of the relationships between the entities has.
Draw this ER Diagram, but note that: Ths diagram should adhere to compressed Chen notation :
The ER diagram consists of four entities: Pet, Challenge, User, and Vote.
The Pet entity has attributes such as id (primary key), name, species, age, and description to store information about each pet profile.
The Challenge entity has attributes such as id (primary key), pet1_id and pet2_id (foreign keys referencing the Pet entity), start_date, end_date, and likes to store information about each challenge between two pets.
The User entity has attributes such as id (primary key), name, and email to store information about users who participate in voting and challenge creation.
The Vote entity has attributes such as id (primary key), challenge_id (foreign key referencing the Challenge entity), user_id (foreign key referencing the User entity), and vote to store information about user's vote for a particular challenge.

Be sure to show cardinality in both directions using Crows Foot notation. Do NOT include the fields/attributes or keys for each entity The business rules to create the Crow’s Foot ERD are: A department employs many employees, but each employee is employed by only one department. Some employees, known as “rovers,” are not assigned to any department. A division operates many departments, but each department is operated by only one division. An employee may be assigned many projects, and a project may have many employees assigned to it. A project must have at least one employee assigned to it.
