Project Specification Page 6
The software required for this project is:
On the Web Server
• Microsoft Windows NT Server 4.0 with Service Pack 4
• Microsoft Internet Information Server (IIS) 4.0
On the Web Client
• Microsoft Windows 95/98/2000/NT-Workstation Operating System
• Recent version of Microsoft Internet Explorer/Netscape Navigator web browser
Approach #1 – The Client/Server Way
This approach will use the six in-built objects of ASP’s Object Model in collaboration withMicrosoft’s ISAPI Extensions MSADO15.DLL and CDONTS.DLL. As a programmer, you will beresponsible for developing HTML pages that carry user responses between the clientbrowser and Web Server. The ASP code bound to your HTML pages should handle all server-side processing including RDBMS Access, Flat File Access, Session Management andApplication Management.
Approach #2 – The Multi Tiered Way
This approach will use the six in-built objects of ASP’s Object Model in collaboration withyour custom DLLs that handle all database traffic. As a programmer, you will beresponsible for developing HTML pages that talk to a custom DLL. This custom DLL shouldtake care of talking to the RDBMS. Remember, you should never instanciate adatabase connection if you’re using the 3-Tiered Approach ! The DLL that youdevelop, should handle all RDBMS Access and Flat File Access. Session and Applicationmanagement must be done using your ASP pages.
Flow of Events

The site can be built using two technological approaches:

• Three-Tiered Architecture using ASP 2.0, COM and SQL Server 7.0

As a programmer, you are responsible for remembering the exam category, currentquestion, max questions and candidate’s score throughout the site. As of now, the best wayto implement all this is using Session variables. Please ensure that you submit the answer to
a separate ASP page for evaluation. You can then jump to the next question after evaluatingthe answer (whether correct or not).
Modus Operandii
Here’s a quick hint about how to proceed with the development of the site:
• Store the Maximum Questions value in a session variable. (refer the ExamCategories table)
• Store the current question in a session variable and increment it when a question isdisplayed.
