Proposed Quality Evaluation Framework to Incorporate Quality Aspects in Web Warehouse Creation

Web Warehouse is a read only repository maintained on the web to effectively handle the relevant data. Web warehouse is a system comprised of various subsystems and process. It supports the organizations in decision making. Quality of data store in web warehouse can affect the quality of decision made. For a valuable decision making it is required to consider the quality aspects in designing and modelling of a web warehouse. Thus data quality is one of the most important issues of the web warehousing system. Quality must be incorporated at different stages of the web warehousing system development. It is necessary to enhance existing data warehousing system to increase the data quality. It results in the storage of high quality data in the repository and efficient decision making. In this paper a Quality Evaluation Framework is proposed keeping in view the quality dimensions associated with different phases of a web warehouse. Further more, the proposed framework is validated empirically with the help of quantitative analysis

Mobile-Learning in Thai Universities:Potential Technological Impacts

Higher education appears to be changing in Thailand, as students, especially young students whose networking concerns match their obsession with mobile technology, may not accept past staid patterns of teaching practices and opt for more contemporary approaches such as mobile-learning. This research used a qualitative approach and conducted a focus group of students exploring their recent experiences of m-Learning at a university in Bangkok. The major results yield a mixed response in terms of student readiness for m-Learning technology demands. The analysis would appear to suggest that there are crucial technological constraints that have to be overcome relating to mobile devices, the media used and the effects of the delivery mechanism; and that these technological constraints have a considerable impact on student’s pedagogic engagement. Future research implications and issues surrounding the development of mobile-Learning in Thai higher education is also discussed

Functions of a Web Warehouse

This paper proposes a web warehouse based approach to facilitating efficiency improvement, information sharing and service personalization for the World Wide Web. We will overview various functions of a web warehouse by considering the following applications: (1) a web warehouse as shared information repository, (2) a web warehouse as large-scale intelligent cache. We conclude that web warehouses will play an important role in digital libraries and other online information services
