Huge volume of structured and unstructured data which is called big data, nowadays, provides opportunities for companies especially those that use electronic commerce (e-commerce). The data is collected from customer's internal processes, vendors, markets and business environment. This paper presents a data mining (DM) process for e-commerce including the three common algorithms: association, clustering and prediction. It also highlights some of the benefits of DM to e-commerce companies in terms of merchandise planning, sale forecasting, basket analysis, customer relationship management and market segmentation which can be achieved with the three data mining algorithms. The main aim of this paper is to review the application of data mining in e-commerce by focusing on structured and unstructured data collected thorough various resources and cloud computing services in order to justify the importance of data mining. Moreover, this study evaluates certain challenges of data mining like spider identification, data transformations and making data model comprehensible to business users. Other challenges which are supporting the slow changing dimensions of data, making the data transformation and model building accessible to business users are also evaluated. A clear guide to e-commerce companies sitting on huge volume of data to easily manipulate the data for business improvement which in return will place them highly competitive among their competitors is also provided in this paper.
The Student Information System (SIS) has increasingly gained popularity among universities for various reasons. However, evaluating student's trust and satisfaction of the system are not fully investigated. In this research, a sample of 634 students participated in the study from Cyprus International University, Cyprus. The Structural Equation Modelling (SEM) technique was employed with AMOS 23 software to identify the trust and satisfaction of students' SIS usage. The study model, which include subjective norm, image, output quality, result demonstrability, perceived usefulness, perceived ease of use, trust and satisfaction, was developed based on extended Technology Acceptance Model (TAM II). Results obtained from the analysis indicated that image, output quality, result demonstrability and perceived ease of use had a significant impact on perceived usefulness. Trust was found to be significantly correlated with satisfaction; however, subjective norm, Perceived usefulness and perceived ease of use did not have a significant influence on satisfaction. Furthermore, the finding confirmed that several constructs in the TAM II that were important in previous studies were not significant in the SIS. The students' behavior aspects are essential for the effective use of the system. It provides valuable information for university management in understanding the challenges of student's trust and satisfaction about SIS usage.
This paper discusses the contributions of communication technologies to modern civilization and globalization and the role of connectivity as facilitator to efficient global information sharing today. The background study of networks, satellites, statement of the problem and the objectives of the paper were looked into. A brief historical development of Nigeria communications and their beneficial applications today were presented. Presentation was made on why internet communications in Nigeria is dominated by wireless/satellite link. It was adduced that the absence of information technology infrastructure, particularly the complete absence of fiber optics backbone and weak telecommunication base were responsible for the predominant wireless internet application in Nigeria. The paper concludes that a good information technology infrastructure base such as the construction of domestic optics backbone as ongoing by some of the GSM operators such as GlobaCom and MTN, launching of domestic communication satellite such as Nigcomsat1R in December, 2012; and the interlinking of our communication will enhance information sharing and as well reduce the cost of internet applications and motivate a larger population to participate in our new information society.
