Repair Shop Management System Database Design

The project repair shop management system is an online platform intended to cater the transactions between the shop owner, technician and customers/clients. The design of this project can be used by computer repair shop, cellphone repair shop, car/auto repair shop and many more.

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

Repair Shop Management System Database Design - List of Tables

tbluser – this table will store the information of personnel who can access the records of the system.

user_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).
username – username of the personnel used to login together with the password.
password – password of the personnel used to login together with the username.
avatar – this will hold the profile image of the user.
fullname – the complete name of the personnel or user.
contact – contact number of the personnel (mobile/cellphone number).
email – email address of the personnel/user.
user_category_id – the user group or category of the user.
status – the value of this column is 0 or 1, 0 means deactivated or inactive, 1 is activated or active.

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