- Please draw the ER diagram. Explain how you know which one is entity, attribute, and all constraints. Explain each step of the diagram.arrow_forwardProvide guidelines for naming and defining relationships in ER-Model.arrow_forwardDraw 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.arrow_forward
- Create a logical data model documented with an ERD using the crow’s foot format. Be sure that each entity has the entity name at the top of the box, the primary key attribute or attributes in the middle of the box, and the non-key attributes in the bottom of the box. Lines should separate each part of the entity box. Follow these instructions about each ERD: ● The ERD must not have any many-to-many (m:n) relationships. ● All attributes must be placed within an entity. ● Each entity must have a primary key defined. A primary key can consist of one or more attributes. ● Each relationship must have a foreign key. Denote the foreign key(s) with the notation (FK) on the ERD. Remember that in a one-to-many relationship, the foreign key is placed in the entity that is on the many side of the relationship. ● Each relationship must include both a maximum and minimum cardinality for both sides of the relationship. ● Each relationship should have a verb or verb phrase to describe it. Question:…arrow_forwardFor each entity, there needs to be an indication of whether it is one-to-one, one-to-many or many-to-many relationship. Here are the answers I have but I could use more guidance with it. I struggle with this type of question.
