In this study, researchers examined how consumer decisions on purchases in e-commerce are particularly influenced by trust, attitudes and the ease of new shopping places. The data collection research was conducted using a questionnaire with 130 consumer respondents who had bought at ecommerce which would later be processed by Amos' Structural Equation Modeling (SEM). The study used four variables, thirteen dimensions and twenty-six indicators. The results showed that trust, convenience and attitudes influenced consumer decisions in buying e-commerce. The results also showed that trust had the greatest and most significant influence on consumer decisions to buy in e-commerce. So, it can be said that consumers buy because it is based on a sense of already trusting an e-commerce to make e-commerce crowded and buyers need to pay attention to improving their taste.

The aim of this study is to identify the link between online sales systems, infrastructure, ease of use & information accuracy in improving Jordanian restaurants’ call centers' performance effectiveness (JRCCPE). In order to achieve the study's objectives, a questionnaire was conducted for measuring the link between online sales systems (OSS), infrastructure, ease of use & information accuracy in improving JRCCPE. The study sample was selected by distributing 220 questionnaires to all employees of Jordanian restaurants’ call centers (JRCC) from the set of employees working in an online sales system where 173 were retrieved. Aiming to answer the study questions and test hypotheses, the researcher extracted the means and standard deviations to apply the multiple regression equation. Accordingly, the study reached many results, showing a statistically significant effect for using the OSS, infrastructure, ease of use & information accuracy in improving JRCCPE. The study suggested that JRCC seeks adding various characteristics of editing, deleting, copying, and setting the time on the basis of text messaging through such networks as well as the need to conduct marketing studies in order to enable companies to achieve the customers' wishes in a method matching their expectations.
