web application is n-tier application interaction between client and n number of users....

Answer / rajendra

CLIENT / SERVER

An issue of client/server is that the application must be
installed on each users computer. Depending on the
complexity of the program, the environment it is written in,
and the care the developer took to package the program, this
can be as easy as creating a shortcut to an executable on a
shared network drive or it can be as hard as spending hours
installing and configuring runtime software and components
on each client computer.


Introduction to 2-Tier Architecture

2-tier architecture is used to describe client/server
systems where the client requests resources and the server
responds directly to the request, using its own resources.
This means that the server does not call on another
application in order to provide part of the service.















Introduction to 3-Tier Architecture

In 3-tier architecture, there is an intermediary level,
meaning the architecture is generally split up between:

1. A client, i.e. the computer, which requests the
resources, equipped with a user interface (usually a web
browser) for presentation purposes
2. The application server (also called middleware), whose
task it is to provide the requested resources, but by
calling on another server
3. The data server, which provides the application server
with the data it requires







Comparing both types of architecture

2-tier architecture is therefore a client-server
architecture where the server is versatile, i.e. it is
capable of directly responding to all of the client's
resource requests.

In 3-tier architecture however, the server-level
applications are remote from one another, i.e. each server
is specialised with a certain task (for example: web
server/database server). 3-tier architecture provides:

* A greater degree of flexibility
* Increased security, as security can be defined for
each service, and at each level
* Increased performance, as tasks are shared between servers

Multi-Tiered Architecture

In 3-tier architecture, each server (tier 2 and 3) performs
a specialised task (a service). A server can therefore use
services from other servers in order to provide its own
service. As a result, 3-tier architecture is potentially an
n-tiered architecture

My company has recently started using Ajax for building UI and QTP is nor recognizing the drop down list for selection.It recognises it as a general Web Element or Web Table. I have added individual selections from the drop down as web Table. It works as long as the page is not refreshed. I need some help and inputs as to how to make QTP recognise a drop down list for selection. Any help will be appreciated.

I got some information from the QTP help.But i am not sure whether through this process will QTP work or not bellow is the Help what I have Remote setup Settings Remote WSH, which is a new technology included in WSH 5.6, provides the ability to run a script on a remote machine or machines. With Remote WSH, the script is physically copied from the local machine to the remote machine before executing. In order to enable Remote WSH functionality, you must first set up the remote machine with the proper security settings. The steps below perform the tasks that enable Remote WSH. Note Both the remote and local machines must be running Windows NT 4 SP3 or greater in order to use Remote WSH. To enable a machine to run remote scripts 1. Install WSH V5.6 on the machine. If you are using Windows 2001 or have installed Internet Explorer 6 or greater, WSH 5.6 has already been installed. Note WSH 5.6 is available for download from the web at http://msdn.microsoft.com/scripting 2. Add yourself to the remote machine's Local Administrators group. 3. To enable Remote WSH, use Poledit.exe on the server. Note An administrator who wants to enable Remote WSH must either acquire the Windows 2000 resource kit, or use http://msdn.microsoft.com/scripting to acquire the necessary windowsscript.adm file that contains the WSH settings. The windowsscript.adm file must be copied to the server that sets the gapplicabel group's policies. Although it is not necessary to copy the file to the server's \WINNT\INF directory, this is nonetheless where the default adm files are located. Note For more information on Poledit.exe, see the Poledit.exe's online help system. 4. WSH should now be enabled on the machine. To test it,. WSH 5.6 can run scripts that reside on remote systems. The following scripts demonstrate this capability. These scripts make the assumption that the files are located on a local machine directory called "c:\wsh5.6"; change the local path and the remote machine name as necessary. After initially running RemoteTest.WSF on the local machine, there may be a small pause as DCOM verifies your identity. After you see the "Done" message, a file named "c:\beenhere.txt" on the remote machine indicates the time that you executed the command (from the remote computer's clock). Script to run scripts remotely set oController = CreateObject("WSHController") set oProcess= oController.CreateScript("c:\wsh5.6\beenhere.wsf","remmachine") oProcess. Execute Could you tell me will it work fine
