Pet shop Management System Database Design

Pet shop Management System Database Design

The capstone project entitled “Pet shop Management System” is a platform that allows the different pet shop owners or managers to post and publish their pet and other products on their pet shop. The platform is an ecommerce website specifically intended for pets, pet shop services, pet shop accessories and other products.

This article will provide you with the list of tables and field/columns for every table in the design of database structure/schema of pet shop management system. The team will later provide a video tutorial on how to create the database in PHPMyAdmin.

This database design has 12 tables with their respective fields and columns as well as their relationships among each other.

Pet shop Management System Database Design - List of Table — Pet shop Management System Database Design – List of Table

tbl_pet – this table will store the information of the different pets posted on the platform by their specific owner/pet shop. The table has the following columns:

pet_id – primary key of the table. It is set usually to auto_increment (the database will automatically give this column a value starting from 1).
pet_description – the detailed description of the pet such as the color, birthday, weight, height, etc.
pet_category_id – this is a foreign key that points out to the pet category table.
vendor_id – this is another foreign key that links to the vendor or shop owner who posted the item/pet information.
pet_images – images of the pet.
pet_status – this refers to the availability of the pet.
user_id – the user who encode/manage/update/approve the posted information.

Create SQL Statement – the statement below is used to create the tbl_pet, copy the sql statement and paste it in the sql manager/tab of your phpmyadmin.
