# Auto Service Information System Specification



This project outlines the specifications for an information system designed to manage an auto service company. The company consists of multiple workstations that offer a range of services and sell various products.



## System Requirements



### Services

- A centralized list of all services offered by the company is maintained.

- Each service is defined by:

  - A unique code

  - Name

  - Price



### Products

- A centralized list of all products for sale is maintained.

- Each product is defined by:

  - A unique code

  - Name

  - Price

  - Quantity in stock



### Workstations

- Each workstation in the auto service company has:

  - A unique identification number

  - Address

- Workstations can offer either the complete set or a subset of services and products available at the company level.

- Users can view all services and products offered by each workstation.



### Clients

Clients of the auto service can be either individuals or companies:

- **Individual Clients**:

  - Name

  - Surname

  - Place of residence

- **Corporate Clients**:

  - Company name

  - Headquarters location

- Each client may own multiple vehicles, with records kept for each vehicle, including:

  - Chassis number

  - Registration plate

  - Brand

  - Model

  - Type of vehicle



### Employees

- Each workstation can have multiple employees, and records are kept for each employee including:

  - Unique employee identification number

  - Name

  - Surname

  - Address

  - Username (for system access)

  - Password (for system access)

  - Job title

- An employee is associated with a single workstation, but a workstation may have multiple employees.

- Each employee can be assigned to multiple work orders, with details of tasks assigned to them recorded.



### Vehicle Intake and Assignment

- Upon vehicle intake, an assignment record is created that includes:

  - The employee who created the assignment (employee ID)

  - The vehicle assigned (chassis number)

  - The workstation handling the assignment (workstation ID)

  - Date of intake

  - Expected completion date

  - Additional description

- After creating an assignment, an initial invoice with an amount of 0.00 and a date is generated.



### Work Orders

- For each assignment, multiple work orders can be created. Each work order includes:

  - Unique work order ID

  - Expected completion date

  - Status

  - Employee who created the work order (employee ID)

- An assignment can have multiple related work orders, but each work order is linked to exactly one assignment.

- Each work order can include various services and products.



### Invoice and Stock Management

- Adding a new service or product to a work order automatically increases the invoice total for the corresponding assignment.

- Removing a service or product from a work order adjusts the invoice amount accordingly and updates the stock quantity of the product.

  - When adding `x` quantity of a product to a work order, the stock level of that product decreases accordingly.

- The system displays the list of services and products in each work order, along with the revenue from sold products and services.



## Implementation Notes

- This project should adhere to:

  - Object-oriented programming principles

  - Clean code practices

  - Variable and function naming conventions consistent with the chosen programming language
