SUMMARY

The wider areas of job searching facilitate the quick and easy access to opportunities. The
increasing job opportunities and changing scenario of the business environment today has
made more people to search for better career and employers to search for better potential. This
situation has pro
mpted many to move to job
s
ites

to look for the ways that has been widely
accepted and fully useful in job searchin
g. In this sense the job site

assumes greater
importance and we could develop such an efficient system which is used by lot many job
hunters and employers.

OpenWindow.com

i
s a web site

for organizations and recruitment companies to manage the
recruitment process in a collaborative environment. The job applicants
can

4 TECHNOLOGIES AND L
ITERATURE REVIEW OF
PAST
WORK/SYSTEM

DOT NET TECHNOLOGY:

The
.NET Framework

(pronounced
dot net
) is a
software framework

that runs
primarily on
Microsoft Windows
. It includes a large
library

and supports several
programming languages

which allows language interoperability (each language can use code
written in other languages). Programs written for the .NET Framework execute in a
software

environment (as contrasted to

hardware

environment), known as the
Common Language
Runtime

(CLR), an
application virtual machine

that provides important services such as
security,
memory management
, and
exception handling
. The class library and the CLR
together constitute the .NET Framework.

The .NET Framework's
Base Class Library

provides
user interface
,
data access
,
database

connectivity
,
cryptography
,
web application

development, numeric
algorithms
, and
network
communications
. Programmers produce software by combining their own
source code

the .NET Framework

and other libraries. The .NET Framework is intended
to be used by most
new applications created for the Windows platform. Microsoft also produces a popular
integrated development
environment

largely for .NET software called
Visual Studio
.

DESIGN FEATURES



Interoperability:


Because computer systems commonly require interaction between new and older
applications, the .NET Framework provides means to access functionality that is
implemented in programs that execute outside the .NET environment. Access to
COM

components is provided in the System.Runtime.InteropServices and
System.EnterpriseServices namespaces of the framework; access to other
functionality is provided using the
P/Invoke

feature.




Common Language Runtime Engine
:


The
Common Language Runtime

(CLR) is the execution engine of the .NET
Framework. All .NET programs execute under the supervision of the CLR,
guaranteeing certain properties and behaviors in the areas of memory management,
security, and exception handling.




Lan
guage Independence
:


The .NET Framework introduces a
Common Type System
, or CTS. The CTS
s
pecification

defines all possible
datatypes

and
programming

constructs supported by
the CLR and how they may or
may not interact with each other conforming to the
Common Language Infrastructure

(CLI) specification. Because of this feature, the
.NET Framewo
rk supports the exchange of types and object instances between
libraries and applications written using any conforming
.NET language
.

Base Class Library


The
Base Class Library

(BCL), part of the Framework Class Library (FCL), is a
library of functionality available to all languages using the .NET Framework. The
BCL provides
classes

which encapsulate a number of common functions, including
file

read
ing and writing,
graphic rendering
,
database

interaction,
XML

document
manipulation and so on.



Simplified Deployment


The .NET Framework includes design features and tools that help manage the
installation

of computer software to ensure that it does not interfere with previously
installed software, and that it conforms to security requirements.



Security


The design is meant to address some of the vulnerabilities, such as
buffer overflows
,
that have been exploited by malicious software. Additionally, .NET provides a
common sec
urity model for all applications.



Portability


While Microsoft has never implemented the full framework on any system except
Microsoft Windows, the framework is engineered to be platform agnostic, and
cross
-
platform implementations are available for other
operating systems.
Microsoft submitted the specifications for the
Common Language Infrastructure




HTML
:

Hypertext Markup Language (HTML) is

a language for describing how pages of text,
graphics, and other Information are organized, formatted, and linked together. It is not really a

programming language in the sense of COBOL or Visual Basic, but it does provide powerful
capabilities for text f
ormatting and output display. The original purpose of HTML was
primarily as a tool for making text documents readily available on the Internet. Basic graphic
support was added, and the things started to take off. Now we have sound, live video, retail
catal
ogs, and much, much more available to us.
HTML pages are the standard interface to the
Internet. This basic language provides the necessary nuts and bolts for building Web page.

HTML stands for Hyper Text Markup Language and was developed specifically for
use on
the system of links, which can be non sequential in order. HTML is not a programming
language. It is a marking up language used for linking one piece of information to
another.Using a markup language means that tags can be added to the words in the
document

and web enable them. A tag is a set of descriptive formatting codes used in HTML document
that instructs a web browser how to display text and graphics on a web page.

HTML 2.0 is the first standard of HTML specification, released in 1996. HTML 3.6

was the
next specification to be developed. It was a joint effort of many software companies like
Microsoft, IBM, Sun Microsystems, Novell and others.
HTML 4.0 is the latest version of
HTML, which includes CSS and dynamic HTML features.

SQL
:

Microsoft
SQL Server

is a
relational database server
, developed by
Mic
rosoft
: It is a software
product whose primary function is to store and retrieve data as requested by other software
applications, be it those on the same computer or those running on another computer across a
network (including the Internet). There are at

least a dozen different editions of Microsoft
SQL Server aimed at different audiences and for different workloads (ranging from small
applications that store and retrieve data on the same computer, to millions of users and
computers that access huge amoun
ts of data from the Internet at the same time).


JAVASCRIPT
:

The project uses JavaScript as the client side scripting language for HTML pages in the
project.JavaScript is an easy to use object

applications that link together resources on both clients and servers. JavaScript is designed for
use by HTML page authors and enterprise application developers to dynamically script the
behavior of objects running on either the client or the servers. Java
Script ‘s design and
concept represent the next generation of software for the Internet


LITERATURE SURVEY
:

E
-
commerce is fast gaining ground as an accepted and used business paradigm. More and
more business houses are implementing web sites providing func
tionality for performing
commercial transactions over the web. It is reasonable to say that the process of shopping on
the web is becoming commonplace. An online store is a virtual store on the Internet where
customers can browse the catalog and select pro
ducts of interest. The selected items may be
collected in a shopping cart. At checkout time, the items in the shopping cart will be presented
as an order. At that time, more information will be needed to complete the transaction.
Usually, the customer will

be asked to fill or select a billing address, a shipping address, a
shipping option, and payment information such as credit card number. An e
-

mail notification
is sent to the customer as soon as the order is placed.


CASE STUDY

CASE STATEMENT:

In this case, we will be designing a simple online shopping
portal .The site will provide
soothing shopping experience for customers. The
system will allow more than one
categories
and different brands under the segment. Th
e case will trace the follo
wing
sequence.

SCENARIO:

A customer visits the online shopping portal. A customer may buy item or just visit the
page
and logout. The customer can select a segment, then a

category, and brand to get the
different
products in the desired brand.

The
customer can select the product for purchasing. The p
rocess can be repeated for more
items. Once the customer finishes selecting the product/s
the cart can be viewed , If the
customer wants to edit the final cart it can be done here.

For final payment the
customer has to login the portal, if the customer is visiting for the 1st

time he must register with the site, else the customer must use the login page to proceed.


Final cart is submitted for payment and card details and address(where shipment has to b
e
made) are be confirmed by the customer .Customer is confirmed with a shipment Id and
delivery of goods within 15 days.
