Design Pattern

3.1 Architectural Design

3.1.1 Problem Specification

This application is to automate the restaurant activities. It provides the facilities

for reserving the seats at restaurant, ordering of food and payment through online..

Customers want better services in less cost and in easy way as well as the organizations

also advertise and selling their products online and through social networks. So the

websites are very simple and powerful way to achieve this goal for both parties. The

Online Restaurant provides the advertisements on the websites, that attract the customers

to know about the items and provides easy and secure mechanism to get items (foods),

services or marketing online. This website provides facilities to the publisher to advertise

their product/services and make deals with customers.

To develop this idea, the architecture design of this system should be very strong.

To store all the customer data, business listing detail and all the functionality, it is

necessary to design a database that can handle all the data and its operation. This can be

understood by the ER-diagram, DFD and Structure chart.

3.1.2 E-R diagram

ER diagram shows entity relation diagram for all entities present into the database

to perform different operations. The database of Online Restaurant application is

composed of many entities.

3.1.3 Data Flow Diagram

A data flow diagram is a representation of the "flow" of data through an information system,

modeling its process aspects. Often they are a preliminary step used so as to create an overview of

the system which can later be elaborated. DFD's can also be used for the visualization of data

processing.

Level 0 DFD

Level 0 DFD is a context diagram of whole restaurant activities process. In this

customer and administrator are external entity. The process is to collect customer

data and process by the admin.

3.2.1 Design Decisions

In the development of this project , the Procedure-Oriented Approach has been used to

assess the performances of various applications. As the procedural approached is followed

for the step by step execution of projects involving a series of steps to be performed to assess

the performances of a software product. Hence the procedural approach is a better model

their problem domains than similar systems produced by traditional techniques.
