SYSTEM DESIGN

INTRODUCTION

System design is the second phase of system’s life cycle. It is the phase in

which detailed design of selected system in the study phase is accomplished and user

oriented specification is connected in to the technical design specification. Principle

activities performed during the design phase include:

Input design

Output design

Database design

Conceptual system design

Data Flow Diagram

Entity-Relationship diagram

Architectural design

Module design

INPUT DESIGN

Input design is the process of converting the user oriented inputs into the

computer-based format. Input design is a part of the overall system design, which requires

careful attention. The major objective of the input design is to make the data entry easier,

logical and error free. With this objective the screens for the system are developed.

In case of Ad server there is number of input screens like login form,

registration form for new advertisers and publishers, form for entering ad details, payment

form for both advertisers and publishers, form for renewing ad duration, form for

requesting ad by publishers ,etc.

OUTPUT DESIGN

A quality output is the one which meets the requirements of the end user

and presents the information clearly. In any system results of processing are given to the

users through the outputs.

Output design should improve the relationship of the system with user and

help in decision making. The objective of the output design is to define the format of all

printed documents and of the screens that will be produced by the system.

In the proposed project it is possible to get various types of reports. The

different types of reports in Ad server are repots showing ad performance, publishers

earnings, etc.

DATABASE DESIGN

The data in the system has to be stored and retrieved from database.

Designing the database is the part of system design. The database of Ad server is a

collection of interrelated data stored in different tables. The MS-SQL server database has

been chosen for developing the relevant database.

TABLE DESIGN

A table is a collection of logically related records. The main objectives of

table design is to provide effective auxiliary storage without any application and to

contribute to the overall efficiency of the computer program components of the whole

system.

CONCEPTUAL SYSTEM DESIGN

After study and the analysis of the existing system the functional operational

requirements were identified. Based on these requirements the conceptual model of the

system is designed. The objective of the system design is to improve the existing system or

design a new system with improved facilities.

Data Flow Diagram (DFD)

A DFD is a structured analysis and design tool that can be used for

flowcharting. A DFD is a network that describes flow of data and process the change or

transforms data through out a system. This is constructed using a set of symbols.


ad_id varchar 15 Primary key

pub_id varchar 15 Primary key

no_of_clicks integer

earnings numeric 6,2

cash_issued numeric 6,2

To represent a data source or a destination

To represent data stream

To represent data storage

A process that transform the data stream

ARCHITECTURAL DESIGN

The primary objective of architectural design is to develop a modular

program structure and represent the relationship between modules. Data flow oriented design

is an architectural design method that allows a convenient transition from the analysis model

to a design description of program structure.

MODULE DESIGN

An important step in the software developing is module separation. Well

defined modules can improve the efficiency and the performance of the software. Ad server

has three important modules. They are:

Client (advertiser) management

User (publisher) management

Ad management

Ad server
