DATABASE DESIGN

Mapping Of Class Diagrams into Tables

Design Approach

All Software design methods share the same goal - to transform a

set of data processing requirements into a computer program. The

major objectives of the software design process are to document in

sufficient detail the software design based on the software requirementsand traceability to specifications. The output is complete, consistent,

correct, testable and understandable information that can be used as

input for code generation. The Functional Specifications and the system

specifications are used as inputs for this process. The process ends

when all the objectives of the software requirement document are met.System Design

System Design is an important phase in which quality is fostered

in software development design is the process that actually transforms

the requirements in to a finished software product (or) system.

Design is the process of translating the requirement prepared

during system study into design. The system design phase employs a

variety of tools such as class diagram and so on.

System design is primarily a synthesis function. In designing a

new system one must have a clear picture of what is required and what

must be done in order to achieve the requirement. Web pages are

designed in such a way that it should be easily understandable for a

layman.

Output Design

The output is the most important direct source of information tothe user. Intelligent output Design will improve the systems

relationship with the user and also helps in decision making, once the

output requirement are determined, the system designer can decide,

what to include in the system and how to structure it, so that the

required output can be produced. Hence the output requirements are to

be determined before going to actual system design.

Output design is based on the following factors.

Layout for the presentation of outputs.

A simple and neat format is preferred rather than complex

form of output.

Input Design

Input Design is a part of overall system design which requires

very care attention. If an error occurs in the input data then the result of

that error may lead to unwanted problems. Errors committed by users

can be controlled by a proper input design. Normally the data will be

keyed into the system through the standard input device like keyboard.

In such case, a validation program should be there to check the validity

of the data.

Database Design

Database design is the most critical part of the design phase. An

elegantly designed, well-defined database can play as a strong

foundation for the whole system. Database design transforms the

information domain model created during the analysis into the data

structures that will be required to implement the software system.

Conceptual Level

Conceptual level describes the major data objects and

relationship between them. This level uses symbols from a modeling

method called Entity Relationship Analysis.

Entity Relationship Analysis uses three major abstractions to

describe data. They are as follows,

Entities: Distinct objects of the system an entity is a conceptual

representation of an object.

Attributes : Properties of the entities.

Relationship: Meaningful interaction between entities.

Relationship between entities makes up the database structure.

Three types of relationship exist among entities. They are,

One-to-One : Association between two entities.

One-to-Many: Association between one entity with two or more

entities.

Many-to-One: Association between two or more entities in both

directions.

9/27

Writing dynamic, high-performance Web application has never been

easier.Asp.Net combines unprecedented developer productivity with

performance, reliability and deployment.

Developer Productivity: -

Asp.Net helps you deliver real world web applications in record time.

Easy Programming Mode: -

Asp.Net makes building real world web

applications dramatically easier. Asp.Net server controls enable an

HTML-like style of declarative programming that let you build great

pages with far less code than with classic Asp. Displaying data,

validating user input, and uploading files are all amazingly easy.

Best of all Asp.Net pages work in all browsers- including Netscape,

Opera, AOL and Internet Explorer

Flexible Language Options: -

Asp.Net lets you leverage your current

programming language skills. Unlike classic Asp, which supports

only interpreted VBScript and Jscript.Asp.Net now supports more

than 25 .Net languages (including built-in support for Vb.Net, C#

and Jscript.Net = no tool required), giving you unprecedented

flexibility in your choice of language.

Great Tool Support: -

You can harness the full power of Asp.Net using

any text editor even Notepad! But Visual Studio .Net adds the

productivity of Visual Basic-style development to the web. Now you

can visually design Asp.Net wed forms using familiar drag-drop-

double click techniques, and enjoy full-fledged code support

including statement completion and color-coding. Vb.Net also

provides integrated support for debugging and deploying Asp.Net

web applications. The Enterprise versions of Visual Studio .Net

deliver life-cycle features to help organizations plan, analyze, design,

build, test and coordinate teams that develop Asp.Net web

applications (conceptual, logical and physical mode) testing tools

(functional, performance and scalability) and enterprise frameworks

and temples, all available within the integrated visual studio .Net

environment.

Rich Class Framework: -

Application features that used to be hard to

implement or required a 3rd party component can now be added in

just a few lines of code using the .Net framework offers over 4500

classes that encapsulate rich functionality like XML, data access, file

upload, regular expressions, image generation, performance

monitoring and logging, transactions, message queuing SMTP mail,

and much more!

3. REQUIREMENTS AND ANALYSIS

[3.1] Problem Definition

As we find many disadvantages in manual system, there are two

options with us. In the current manual system we have to work

manually. In manual system we have to make every type ofregister manually with validation, but in this system we gain

report as per our requirements in a moment.

All their transaction related works are doing locally

Disadvantage of Manual System:-

Require more accuracy

Require more resource

High probability of error

Highly cumbersome

Time Consuming

Maintenance is also problem

[3.2] Requirements Specification

Online Banking System falls in the second category. Everything

that describes as disadvantages of the current manual system

becomes advantages here. Literally you can do everything that is

needed, electronically by just pressing the specified buttons and

filling required information.

Manual record keeping system is cumbersome to get particular

records.

OnLine eXchange 11


12/27

There is no central place from where people from different

departments can get proper information.

Lack of central location leads to inconvenience and inadequate

information.

Besides these, there is some possibility of errors in manual

system. So one cant get reliable information.

From this manual system one cannot get up-to-date information

related to projects within various departments. This would

provide miss-leading information to the organization.

As there was no central source of information about Members and

Teams and them file and projects in various departments of

company, getting information was very inconvenient.

There needs to be an online portal for the data, which can be used

by all departments, accessed from anywhere through any pc &

data needs to reside on a common server under the control of

server administrator to ensure data integrity and security.

Because of various limitations, new system is needed to be

centralized.

The purpose of the project is to automate the payroll process and

keep all the details related to an employee in a central storage.

So using ASP.NET as front end and Microsoft SQL Server 2000

as back end develops the new system. The requirement easily

fulfilled with ASP.NET as it provides way for building dynamic,database driven websites.

Hence, the existing system is replaced by the new system, which

is based on ASP.NET and SQL Server 2000.

The main purpose behind this is to increase the productivity of

the admin staff and relieve them from the monotonous activity.

For increase their customer Hi-tech recommended this system.

This is system is beneficially for their customer. Friendly

environment will be created.

To solve the time related problem.

Customer record will be properly handling after use this system.

Planning and Scheduling

Planning and scheduling is a complicated part of the software

development .planning for our purpose, can be through of as

determining all the small task that must be carried out in order to

accomplish the goal. Planning also takes into account, rules, known as

constraints which control when certain task can or cannot happen.

Scheduling can be through of as determining whether adequate

resources are available to carry out the plan. You should show Gantt

chart and program Evaluation review Technique (Pert).

Project scheduling chart

Scheduling the project task is an important project planning

activity .It involves deciding which tasks would be taken up when.

Based on the planned duration of required tests and collection of

resources to complete those tasks projected completion date iscalculated. We have prepared timeline Chart shown as below fig.
