Which of the following is NOT one of the three e-commerce models?

• A. Sell-side system
• B. Electronic marketplace
• C. Buy-side system
• D. Online trading community

Answer: (D)

In e-commerce taxonomy, the three main B2B models describe how buyers and sellers connect: a sell-side system where the vendor hosts a catalog and sells directly to buyers; a buy-side system where the buying organization uses its procurement tools to source from multiple suppliers; and an electronic marketplace that serves as a neutral platform linking many buyers with many sellers. An online trading community, while it can describe a network where participants trade and share information, isn’t classified as one of these three canonical models. It’s a broader concept of a trading network rather than a distinct standard model. Therefore it isn’t part of the three e-commerce models.
