摘要:这是一篇数据仓库系统相关的留学生论文,主要论述了Data Warehouse Systems在全球化经济不断发展的今天对企业和整个社会的重大影响力。

d in disclosing some of the research issues or might have ignored some key facts. In that case, our research will not show the actual position of the problem. It will be just a photocopy of the original research. Also, a systematic presentation of data is essential for giving factual information to others and facilitating further statistical calculations and interpretations. As the original research is the base of our findings, the processes adopted by it are very important to us. Through the research processes, we will be able to make out the steps adopted by the original researcher in studying his research problem along with the logic behind them. Thus, knowing the background of the original researcher and the processes adopted by him/her will facilitate us to adjust our research findings accordingly.


Reliability of data: The researcher should test the reliability and certain things about the historical data such as who had collected the data? What were the origins of information? Was it gathered by using appropriate and effective techniques? The time when the data and information was collected. What degree of precision was sought after and was the researcher able to achieve it? In this research analysis, the researcher is bound to find out the reliability of the previous studies. He has not used all the articles and previous studies.


Suitability of the data: The data, which is suitable for one enquiry may not necessarily be found in another enquiry. Hence, it was essential for the researcher to be very careful at the time of scrutinizing various terms and definition and units of collection, which was a very time consuming task for him.


Adequacy of data: If the level of accuracy achieved in data is found inadequate for the purpose of the present research, this data would be considered as inadequate and should not be used by the researcher. At the time of research, this situation was faced by him on a frequent basis because after analyzing the data, when he found that it was inadequate, all the things were vanished.


The questionnaire research methodology and the data collection plan used by the researcher also have some limitation, which are as follows:


Low rate of return of the duly filled in questionnaires and bias due to no-response is often indeterminate.


It can be used only when respondents are educated and cooperating.


The control over questionnaire may be lost once it is sent.


There is an inbuilt inflexibility because of the difficulty of amending the approach once questionnaires have been dispatched.


There is also a possibility of ambiguous replies or omission of replies altogether to certain questions and interpretation of omissions is difficult.


It is difficult to know whether willing respondents are truly representative.


This method is likely to be the slowest of all.
