3. ABSTRACT
Nowadays web services technology is widely used to integrate heterogeneous systems
and develop new applications. Here an application of integration of Digtial Cafe
management systems by web services technology is presented to ease the functioning of
café and canteens management in Universities. Digital Cafe Management integrates lots
of systems such as Ordering System Kitchen Order Ticket (KOT),Billing System,
Customer Relationship Management system(CRM) together. This integration solution can
add or expand hotel or in our case college cafeteria software system in any size of
cafeteria chains environment. This system increases quality and speed of service. This
system also increases attraction of place for large range of customers. Implementing this
system gives a cost-efficient opportunity to give your customers a personalized service
experience where they are in control choosing what they want,when they want it – from
dining to ordering to payment and feedback. Extensive Surveying and Analysis for the
system being proposed and the results procured and complied. Using the data complied
detailed diagrams have been design to capture the flow and the activities of the
envisioned system to be implemented.This can be further implemented using android
application for Tablet PC’s. The front end will be developed using JAVA Android and the
backend will work on MySQL database.

4. 1. Introduction
Online ordering system is originally designed for use in college cafeterias, but just as
applicable in any food delivery industry. The main advantage of this system is that it
greatly simplifies the ordering process for both the customer and the restaurant. By
making entire process of taking orders is automatically the load on restaurants end is
lightened. Once an order is placed on the webpage that will be designed, it is placed into
the database and then retrieved, in pretty much real-time, by a desktop application on the
restaurants end. Within this application, all items in the order are displayed, along with
their corresponding options and delivery details, in a concise and easy to read manner.
This allows the restaurant employees to quickly go through the orders as they are placed
and produce the necessary items with minimal delay and confusion. The greatest
advantage of this system is its Flexibility. The architecture attempts at a full coverage of
the three main areas of restaurant: the Serving area, the Kitchen, and the Manager
counter. The main components of this system are:
1. The android application with the customers allow them todirectly view the menu card
and order immediately.
2. The server application on the restaurant-owner’s desktop/tablet to customize menu and
keep track of customer records.
3. The central database for restaurant-owner to store updated menu information, order
details and broadcast various offers and promotions.
4. Wireless connectivity between the three main areas of restaurant.This proposed system
has following modules

5. Literature Review
In [1] an automated food ordering system is proposed which will keep track of user orders
smartly. Basically, they implemented a food ordering system for different type of restaurants in
which user will make order or make customfood by one click only. By means of android
application for Tablet PCs this system was implemented. The front end was developed using
JAVA, Android and at the backend MySQL database was used. In [2] Customer using a
Smartphone is considered as a basic assumption for the system. When the customer approach to
the restaurant, the saved order can be confirmed by touching the Smartphone. The list of selected
preordered items shall be shown on the kitchen screen, and when confirmed, order slip shall be
printed for further order processing. The solution provides easy and convenient way to select
pre-order transaction form customers. In [3] there was an attempt to design and implementation
of digital dining in restaurants using android technology. This system was a basic dynamic
database utility system which fetches all information from a centralized database. This
application improved the accuracy and efficiency of restaurants as well as human errors. Earlier
drawbacks of automated food ordering systems were overcome by this system and it requires a
onetime investment for gadgets. In [4] an application of integration of hotel management systems
by web services technology is presented. Ordering System Kitchen Order Ticket (KOT), Billing
System, Customer Relationship Management system (CRM) are held together by the Digital
Hotel Management. Add or expand of hotel software system in any size of hotel chains
environment was possible with this solution. In [5] research work aims to design and develop a
wireless food ordering system in the restaurant. Technical operations of Wireless Ordering
System (WOS) including systems architecture, function, limitations and recommendations were
presented in this system. By providing higher quality customer service and reducing human
errors to improve the management aspect for restaurants, pervasive application will be a valuable
tool due to the high demands of handheld devices such as PDAs. In [6] along with customer
feedback for a restaurant a design and execution of wireless food ordering system was carried
out. It enables restaurant owners to setup the system in wireless environment and update menu
presentations easily. Smart phone has been integrated in the customizable wireless food ordering
system with real-time customer feedback implementation to facilitate real-time communication
between restaurant owners and customers. In Paper [7], the purpose of this study was to
investigate the factors that influence the attitude of internet users towards online food ordering in

6. Turkey among university students. A Technology Acceptance Model (TAM) developed by Davis
in 1986 was used to study adoption of Web environment for food ordering. Trust, Innovativeness
and External Influences are added to the model as main factors along with TAM. In Paper [8],
the research work aims to automate the food ordering process in restaurant and also improve the
dining experience of customers. Design implementation of food ordering system for restaurants
were discuss in this paper. This system implements wireless data access to servers. The android
application on user’s mobile will have all the menu details. Kitchen and cashier receives the
order details from the customer mobile wirelessly. These order details are updated in the central
database. The restaurant owner can manage the menu modifications easily. In Paper [9], this
research works on efforts taken by owners of restaurants to adopt information and
communication technologies such as PDA, wireless LAN, costly multi-touch screens, etc. to
enhance dining experience. This paper highlights some of the limitations of the conventional
paper based and PDA-based food ordering system and proposed the low-cost touch screen-based
Restaurant Management System using an android Smartphone or tablet as a solution.

7. 2. Analysis
- Current System Analysis
In FC the Customers (the students and the faculties) first refer to one of the few menu
cards present to place the order. This entity has to now wait in a queue which moves
towards the cashier where the order is placed The cashier (The second actor) now
receives the order from the customer and enters it into their system where they can
calculate the total amount and prints the bill.The cashier then requests for either cash or
card for the payment and the customer proceeds to make the payment.The bill is then
submitted by the customer at the counter.The counter then conveys the order to the
kitchen where the meal is then prepared.The counter receives the order from the
kitchen .The customer can then go and collect the order from the counter.
- Existing System Analysis
The proposed system is developed to manage ordering activities in fast food restaurant. It
helps to record customer submitted orders. After extensive research and going through
many research papers and articles we found out the steps involved in design a suitable
system from existing case studies and summarized that the system should cover the
following functions in order to support the restaurant’s business process for achieving the
objectives:
1.To allow the customer to make order, view order and make changes before submitting
their order and allow them make payment through prepayment card or credit card or debit
card.
2.To provide interface that allows promotion and menu.
3.Tools that generate reports that can be used for decision making
4. A tool that allows the management to modify the food information such asprice, add a
new menu and many others as well as tools for managing user,system menu and
promotion records

8. Survey
The survey was conducted through google forms which were filled in by the students of
VIT, Vellore who have experienced the food courts multiple times.The survey was
conducted to analyze the response to the current system in an attempt to better it .Over 70
students across the campus shared and rated their experience at FC and DC food
courts.The survey spread some light onto the problems and complaints agaisnt the current
system some of them are listed below. Time taken to place order is too much during peek
hours,Long queues,No bill provided to keep,Too little staff to take orders,No UPI or other
alternate online banking methods accepted.
The following are some of the survey questioned asked.
1. Rating of FC/DC on a scale of 1-5
2. Waiting time in clue for ordering and billing in DC

9. 3. Students preferring an app/web page to place order and make payments in FC/DC
From the survey we also found out the most anticipated features and the features
that needs to be implemented. They are listed down below in the order from most
required to the least.
- Feature for hostel delivery
- Check the seat availability
- To place take away orders
-To book and reserve Seats
-To order food in advance and to receive notification realted to its progresses
-Estimated time before order is ready for pick up
