Answer / sunilmn
Two-tier architecture is a client/server architecture ,
where a request to do some task is sent to the server and
the server responds by performing the task.where as a three-
tier or a multi tier architecture has client, server and
database. Where the client request is sent to the server
and the server in turn sends the request to the database.
The database sends back the information/data required to
the server which inturn sends it to the client.

Hi All,
Let it simplify a bit
2-tier application is the client -server aplication with
frontend and backend.
At frontend there would be forms, reports which gets filled
and monitored by backend.
3-tier application has
presentation layer (browser)
Application layer (code)
Database layer (Database-tables,views,procedures )
web application comes under 3 -tier and window based or
desktop aplication falls under 2-tier.
Suggestions are welcome

Projects are broadly divided into two types of :
2 tier applications
3 tier applications
CLIENT / SERVER TESTING
[a] This type of testing usually done for 2 tier
applications (usually developed for LAN)
Here we will be having frontend and backend.
The application launched on frontend will be having forms
and reports which will be monitoring and manipulating data
Eg : applications developed in VB,VC++,Core
Java,C,C++,D2K,PowerBuilder etc.,
The backend for these applications would be MS Access, SQL
Server, oracle, sybase, mysql, quadbase
The tests performed on these type of applications would be
- user interface testing
- manual support testing
- Functionality testing
- compatability testing & configuration testing
- intersystems testing
WEB TESTING
[b] This is done for 3 tier applications (developed for
Internet / intranet / xtranet)
Here we will be having Browser, web server and DB server.
The applications accessable in browser would be developed
in HTML, DHTML, XML, JavaScript etc.,
(we can monitor thru these applications)
Applications for the webserver would be developed in Adv
Java, ASP, JSP, VBScript, JavaScript, Perl, ColdFusion, PHP
etc.,
(all the manipulations are done on the web server with the
help of these programs developed)
The DBserver would be having oracle, sql server, sybase,
mysql etc.,
(all data is stored in the database available on the DB
server)
The tests performed on these type of applications would be
- user interface testing
- Functionality testing
- security testing
- browser compatability testing
- load / stress testing
- interoperability testing/intersystems testing
- storage and data volume testing
