This data may also contain important information related to the strategic decision-making and the space being used by the university. All of these functional areas could be interconnected. To obtain additional details, the user may use drill-down technology. It includes both the historical and current data so that the institutions can have a look at the trends over the time period. The data ware house allows the accessibility of multi-year data.

Data Warehouse Access tools

To measure the perceived usefulness of Information Technology systems, Fred Davis did a study of two scales in the year 1989. It was supposed that both these factors had an effect on the user's acceptance of the user technology (Adams, Nelson and Todd, 1992). In 1992, the study report was repeated by Adams, Nelson, and Todd to study the mental attitude of users toward messaging technology through both voice and electronic mail. It was also used to analyze the attitude of customers toward word spreadsheets, graphics and processing. The studies carried by them showed that these scales were effectual in evaluating the significance of easiness to use. These factors are important in determining the use of system (Adams, et al., 1992). The studies also distinguish that there may be some execution factors that determine the use of technology; for example training, support, user involvement, and user expectations. These factors may determine the assessment of the value of the technology.

The proposal conducted through the research study will look at the users' perceptions of the usefulness and ease of the use of the tools, which are available for accessing the data mart, data warehouse and operational data stores at the place of university. The scales designed by Nelson, et al., will be applied in the survey that is conducted.

It was indicated by Adam, et al. that analyzing the relationship between ease of use, usefulness and usage of information technology is tricky. This was because the use of the systems was frequently required and was based on the job responsibilities of individuals (Adams, et al., 1992). In this study, the use of the data management systems included is not generally required. The investigation will point out whether the individual has been required to use these systems or not. It may be the only alternative for getting the information needed to perform one's job responsibilities, if the system is not required. As a result, this factor may require further study.

The information access layer is defined as the component of the data warehouse that allows the user to access the data (Chen & Frolick, 2000). To make the data available to the end-user in an easy fashion is the main goal of the information access layer. Most of the information access layers use graphic user interface (GUI) applications to run on the desktop computer (Chen & Frolick, 2000). The factors that show the im本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
