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.
