Run the set up wizard to install web services
and various other components
Simply check the items to be installed

Console (MMC) a window based tool that
enables the management of all the web
services & applications from a single window

ASP Technology


Active Server Page (ASP) is an open
environment where one can combine HTML,
scripts and reusable components to create
dynamic and powerful web-based business
solutions
ASP runs as service of web server and is
optimised for multiple threads & multiple
users
ASP File



File created with Active server Pages have the
extension .ASP
ASP file is simply a file that contains HTML,
scripts & calls to components
When a change is made in the ASP file on the
server, you need only save the changes to the
file – the next time web page is loaded, the
script will automatically be compiled
ASP Built-in Objects

Request


Response


To get information from the user
To send information to the user
Server

To control the IIS
ASP Built-in Objects

Session


To store information about the user’s current webserver session
Application

To share application-level information & control
settings for the life-time of the application
Examples of ASP Applications


A web-based Personnel Information System
(Leave Monitoring System, HBA Monitoring
System and other modules which form part of
employee’s career cycle)
Integrated on-line store, inventory and orderprocessing system
Dynamic HTML



HTML provides limited interactivity to web
pages
DHTML extends HTML with an object model
allowing scripting of the objects to change
the styles and attributes of page elements
Allows developers to bring more creativity
and control to web pages, thereby adding
dynamic behaviour
Examples of DHTML Use

Business Applications


DHTML can help build dynamic forms (e.g. master
detail order entry forms) and can respond to user
input, recalculate on the fly and obtain additional
information in the background
Interactive Documents

Documents delivered over the internet are
essentially confined to page-by-page metaphor,
whereas DHTML creates interactive documents
that responds instantly to user actions
Examples of DHTML Use

Dynamic Expansion


With DHTML Search Result pages can be
programmed using scripts to provide a detailed
listing as the mouse passes over it thereby,
eliminating redundant fetches from the server
Table Manipulation

Tabular data such as Price lists can be sorted,
filtered & viewed using local database engine
IIS Application


An IIS (Internet Information Server)
application is a Visual Basic application that
lives on a Web server and responds to
requests from the browser
An IIS application uses HTML to present its
user interface and uses compiled Visual Basic
code to process requests and respond to
events in the browser
IIS Application


To the user, an IIS application appears to be
made up of a series of HTML pages
To the developer, an IIS application is made
up of a special type of object called a
webclass, that in turn contains a series of
resources called webitems
IIS Application



The webclass acts as the central functional
unit of the application, processing data from
the browser and sending information to the
users
A series of procedures are defined that
determine how the webclass responds to
these requests
The webitems are the HTML pages and other
data the webclass can send to the browser in
response to a request
IIS Application vs ASP Application


IIS
applications
resemblance to
applications
bear
Active
a
superficial
Server Pages
Both types of applications present dynamic
Web sites and perform their processing on
the server rather than the client
IIS Application vs ASP Application


However, each has its unique advantages. Active
Server Pages are for script developers interested in
authoring Web pages, and offer the unique capability
of intermingling script with HTML
IIS applications are for Visual Basic developers
building Web-based applications, rather than Web
pages. IIS applications allow for complicated
business processing and easy access from almost any
browser or platform
IIS Application vs DHTML Application

Like IIS applications, DHTML applications also allow
you to respond to events in an HTML page. However,
there are several key differences between the two
types of applications:

Object model — DHTML applications use a different object
model than IIS applications to access and work with the
elements on an HTML page. While IIS applications use the
Active Server Pages object model, DHTML applications use
the DHTML object model
IIS Application vs DHTML Application


Location of processing — IIS applications are designed to
perform most of their processing on the Web server, but
DHTML applications perform most of their processing on the
browser machine. You do not create any Web server
components when you create a DHTML application
Dependency — DHTML applications are intended for use on
intranets, and are dependent on Internet Explorer 4.0 or
later, while IIS applications can be used on the Internet or
an intranet. End users of an IIS application do not need a
specific
operating
system
or
browser
Browser-IIS Interaction


Browser sends an HTTP request to the IIS for
a page on the web server
The web server gets the requested page and
processes the server side scripts, (which are
enclosed within delimiters “<%” and “%>).
The scripts can assign values to variables or
request information from server (interaction
with other tiers)
Browser-IIS Interaction

The processed page containing only
HTML and client-side scripts, if any, is
sent to the browser
Case Study – Web based Reports of
RuralSoft


RuralSoft Reports are a combination of IIS
Application and ASP based web pages
The web-site to host the Reports is prepared
using ASP technology (InterDev6.0) and the
actual reports have been developed using IIS
Application, thus combining the power of the
two technologies


The Reports further interact with data
services
components

in
Microsoft Transaction Server (MTS) to
fetch the data from the database
