Over the past few years, more and more companies have been investing in electronic commerce (EC) by designing and implementing Web-based applications. In the world of practice, the importance of using Web technology to reach individual customers has been presented by many researchers. This paper presents an easy way of conducting marketing research for a Web-based survey in Microsoft Visual Studio 2005. The approach described in this paper helps students to fully understand Three-Tier design architecture, which requires only a single line of code when developing a Web-based survey in ASP.Net 2.0. The paper concludes with a discussion of "lessons learned" and suggestions for effectively teaching a questionnaire survey design in an EC design course.
