About this ER diagram for a pet adoption system

The ER diagram for the pet adoption system shows how animals are made available through the shelter. It also connects each animal to an individual organization. It also depicts the current status of all the animals. The system consists of three primary entities: user, pet, and shelter.

Adopter details like user_id, name, email, and phone are stored in the user entity. This information is crucial after the adoption. Users can create and update appointments using the appointment entity with shelters. Each appointment includes app_id, date, time, and status.

Pet is the core concept in the system. It keeps all the information about the animals ready for adoption. Every pet has a pet_id and properties such as name, age, gender, and location. Pets are organized by type. This includes species, breed, size, and life expectancy.

The shelter has a shelter_id, name, and contact details. It also tracks the link between pets and their temporary homes. The adoption workflow is formalized through the adoption application entity. This entity tracks application status, approval dates, and reasons for decisions.

The system consists of a payment entity that deals with adoption fee payments. Post-adoption feedback is saved in a review entity. It has these fields: rev_id, ratings, comments, and reviewer.

This ER diagram for the pet adoption system outlines the entire adoption process. It covers everything from the initial inquiry to post-adoption care. It helps shelters track and manage their animals. Also, it shows potential adopters which animals are available and the status of their applications. The user–pets–shelter relationships create a strong platform for adoptable animals and those looking to adopt.
