Besides significant benefits, the trend of e-commerce development gives rise to a lot of challenges in terms of developing trust between the company and the consumer. A lack of trust leads to withdrawal from e-transactions. The paper is thus aimed at identifying and explaining the most important factors that affect the increase in users' trust in e-transactions. Besides an analysis of available papers in this area, a field research was conducted on a sample of 512 respondents in Bosnia and Herzegovina in order to develop a structural model of users' trust in e-transactions. Research findings confirm that the basic factors of an online trust model are: website usability, privacy, security, expected product performance, loyalty, and electronic management of customer relations (e-CRM).
This paper presents an approach to the automated design of the initial conceptual database model. The UML activity diagram, as a frequently used business process modeling notation, is used as the starting point for the automated generation of the UML class diagram representing the conceptual database model. Formal rules for automated generation cover the automatic extraction of business objects and business process participants, as well as the automatic generation of corresponding classes and their associations. Based on these rules we have implemented an automatic generator and evaluated it on a real business model.
