<![CDATA[The increasing competition in hotel business forces every hotel to be equiped with analysis tools that can maximize its marketing performance. This paper discusses the development of a data warehouse model and analytic tools to enhance the company's competitive advantage through the utilization of a variety of data, information and knowledge held by the company as a raw material in the decision making process. A study is done at ABC Hotel which uses a database to save the transactional record. However, the database cannot be directly used to support analysis and decision making process. Based on this issue, the company needs a data warehouse model and analytic tools that can be used to store large amounts of data and also potentially to gain a new perspective of data distribution which allows to provide reporting and answers of ad hoc users questions and assist managers in making decisions. Further data warehouse model and analytic tools can be used to help manager to formulate planning and marketing strategies. Data are collected through interviews and literature study, followed by data analysis to analyze business processes, to identify the problems and the information to support analysis process. Furthermore, data warehouse is designed using analysis of records related to the activities in hotel's marketing area and data warehouse model. The result of this paper is data warehouse model and analytic tools to analyze the external and transactional data and to support decision making process in marketing area.]]>

Currently, the university uses a database to store records of transactions which can not directly be used to assist analysis and decision making. Based on these issues then made the data warehouse design used to store large amounts of data and also has the potential to gain new data distribution perspectives and allows to answer the ad hoc question as well as to perform data analysis. The method used consists of: record analysis related to students’ academic achievement, designing data warehouse and data mining. The paper’s results are in a form of data warehouse and data mining design and its implementation with the classification techniques and association rules. From these results can be seen the students’ tendency and pattern background in choosing the specialization, to help them make decisions. ]]>

<![CDATA[Competitive environment among investment firms encourage them to be able to conduct analysis related to investments activities with the potential failure of transfers’ funds. The purpose of this writing is to analyze the needs of the information required in the process of analysis the potential failure of funds transferring in a process of buying and selling stocks and using data mining techniques (Clustering) to support analysis process of the failure of fund transfrerring in a process of buying and selling stocks . Data collection methods used in this study consists of: Literature study, interviews and observations. While the implementation phase of data mining techniques consist of: Data Cleaning, Data Integration, Data Selection, Data Transformation, Data Mining, Pattern Evaluation and Knowledge Presentation. Data mining technique is used to analyze the data in order to know which transactions can lead to failed transfers funds and group them based on Receiving Failure. The clustering result will produce knowledge that is useful in the decision making especially to the top management level. The conclusions of this writing is using data mining techniques that have been designed in this writing, help the management take decisions with more precise so as to avoid losses for company.]]>
