Silverman et al. (2001) identified three levels of DSS in e-commerce shopping websites: access focused, transaction focused, and relationship focused. The first level websites only offer simple user-pulled information access, such as basic search and browsing capabilities; the second level websites interactively offer more support for buyer’s mental processes, e.g. provide default settings and templates, guided choices, and well-structured steps; the third level websites focus on maintaining long term relationship with the customers and are similar to Customer Relationship Management (CRM) systems. Kurnia (2006) discover the adoption of e-commerce in Indonesia, as an example of a developing country, and its relevance by assessing the adoption level, benefits experienced, negative consequences and problems encountered due to electronic commerce adoption. Some factors affecting the adoption of e- commerce and the condition of Indonesia in relation to e-commerce adoption are discussed in this paper. The findings of the research conducted so far indicate a positive growth of e-commerce adoption in Indonesia. Based on the study, it appears that e- commerce is indeed relevant to Indonesia, despite the current limitations with the existing infrastructure and other issues related to the economical and socio- cultural conditions. E-commerce may offer excellent opportunities for growth in developing nations like Indonesia. Further research into the Indonesian situation is needed to better understand the adoptionissue. In addition, other limitation of this article is that it does not show technical part of electronic commerce.
