Super Take-out System

Problem Description

Traditional take-out industry mostly depends on the artificial way to conduct a series of management. For example, when receiving orders, it requires people to record dishes, delivery address and guests’ telephone number, and to calculate the take-out cost, which not only wastes time and reduces the efficiency, but also increases the cost, reduces the profits of the industry, and then makes the traditional take-out consumption suffer bottleneck limitation. Besides that, traditional take-out industry’ marketing means such as publicity and external service are confined to the original medium, for example, to distribute leaflets still needs human to complete. The traditional shop take-out management also adopts papery materials to save information. This method is inconvenient to query or update and easy to tear, and it is also difficult to save with low confidentiality.

In take-out industry, the e-commerce is still in the initial stage of development. But with the continuous increase of Internet users, and accelerating pace of people’ work and life, the network consumption demand will be huge, while the online meal ordering is just developed in this context. Online meal ordering can largely reduce the waste of time, and at the same time help merchants earn more profits, so the network online meal order is bound to become a part of young Internet users’especially white-collars’life.

System Capabilities

The new system should capable of:
Collecting the basic information, phone number, address, ordered take-out products of consumers
Collecting the basic information, phone number, address, unit price of delivery products, and the delivery fee of the merchants.
Allowing merchants inquire consumers’ order information
Connecting System through various devices (I.E. desktop and smart phones)

Business benefits

save operating cost for merchants
improve the ordering efficiency
obtain more detailed and accurate consumer information
provide more efficient publicity channels
offer more excellent customer experience

3.1 Functional Requirements

Web Order System Module

This allows the customer to interact with the system by placing an order. For the restaurant customers to complete this task, they need to provide the following functions:

1. Create an account

2. Manage their accounts

3. Log in to the system

4. Go to the restaurant menu

5. Select an item from the menu.

6. Add a project to the current order.

7. View their current order.

8. Delete item / delete all items from the current order.

9. Provide payment details.

10. Place an order.

11. Receive confirmation in order form.

12. View the order

Menu management system module

The module provides a powerful user with only the functionality of the administrator. No other users of the system (such as restaurant employees or customers) are not available.

Using the graphical interface, it will allow the administrator to manage the menu that is displayed to users of the Web subscription system:

1. Add / update / delete food categories from the menu.

2. Add / update / delete food from the menu.

3. Update the price of the given food.

4. Update the additional information (description, photo, etc.) of the given food

Order Retrieval System Module

This is the simplest module in all three modules. Its design is only used by restaurant staff and offers the following features:

1. Retrieve a new order from the database.

2. Display the order in an easy-to-read, graphical way.

Restaurant staff offers the following features:

•Log in system

•View pending orders

•Mark the order status as delivered or delivered

•Cancel order

3.2 Non-functional Requirements

The subcategories of non-functional requirements given are security and performance requirements.

Security

The identified non-functional security requirements include:

• All data transmitted over the network will be encrypted using openSSl.

• All employees can only log in to one device at a time

• The password strength for all users will be performed during account creation.

Performance requirements

The server can support at least 200 connections at the same time.

The server can support any number of activities, in any case will not lose the meal / order and any payment will not be lost

3.3 software and hardware requirements

Supported hardware platforms

For initial development of Take-out management system only a single computer is required. The recommended minimum system should have 3GHz processor, 4GB RAM, and disk space as required. For a typical, full deployment of take-out management system, the minimum hardware environment should have:

Web application server - 3 GHz processor, 4GB RAM, 30GB disk
Database server -3 GHz processor, 4GB RAM, 100 GB RAID 4 + disk
File-server - 2 GHz processor, 512 MB RAM, RAID 5 storage with appropriate disk space
Application cluster - Application-dependent sizing

Prerequisite Software Requirements

The following software applications must be available on the planned hardware environment before installing the take-out management system. The applications are:

Browser (one required, client-side)
Web application server (one required, server-side)
Relational Database (one required, server-side)
File vault server (one required, server-side)

Server-side Software Requirements

Web Application Server (1 required) - Apache Tomcat
Relational Database Server (1 required) - MariaDB database server

Client side software requirements

The client side the following software to be to access the system:

A web browser – Firefox version 41 and above, Microsoft internet explorer version 11 and above or Chrome.

Java Web Start (Standard Edition) version 1.4.2 - 1.5.0

UML DESIGN Use Cases In order to facilitate a clear and clear view of how end users interact with the system, actors (end users), use case diagrams, and detailed use cases are described for use cases. Find the use cases that are used to log in, log out, add menu items, update menu items, delete menu items, add employees, delete employees, place orders, process payments, accept orders, and deliver items.
Actors
There are three actors in system including the admin, restaurant employee/waiter and customer. The Admin is a super actor and can access virtually everything in the system
