    The organization has optimized databases which are used in current operations and also used as a part of decision support. What is the next step? Data Warehouses and Data Mining are indispensable and inseparable parts for modern organization. Organizations will create data warehouses in order for them to be used by business executives to take important decisions. And as data volume is very large, and a simple filtration of data is not enough in taking decisions, Data Mining techniques will be called on. What must an organization do to implement a Data Warehouse and a Data Mining? Is this investment profitable (especially in the conditions of economic crisis)? In the followings we will try to answer these questions.database, data warehouse, data mining, decision, implementing, investment

    Knowledge discovery and data mining software (Knowledge Discovery and Data Mining - KDD) as an interdisciplinary field emersion have been in rapid growth to merge databases, statistics, industries closely related to the desire to extract valuable information and knowledge in a volume as possible.There is a difference in understanding of "knowledge discovery" and "data mining." Discovery information (Knowledge Discovery) in the database is a process to identify patterns / templates of valid data, innovative, useful and, in the last measure, understandable.data mining, knowledge discovery, data warehouse, data mining tools, data mining applications

    Higher education institution must be able to well perform processes of evaluation, planning and management in order to win the competition in this globalization era. To support any effort of the aforementioned, the institution needs qualified and sufficient information supports so that it can probe and predict any potential strength which existed. Development data warehouse and data mining is kinds of solution alternatives which can be done to help organization in finding and understanding hidden patterns from the data provided. Data warehouse is a collection of integrated databases which is used to support the process of decision making. Data mining is a kind of analysis tool which is used to extract any information provided in the data warehouse. The research discussed a problem in designing data warehouse and applying data mining to support the academic system at IBI Darmajaya in representing potential information required for better academic services to learners. The first executed steps was establishing the data warehouse of IBI Darmajaya, then an analysis was conducted towards all saved data in the data warehouse by using data mining techniques. The results of this research is a data warehouse that can represent information to support the evaluation process and acceptance of new students campaign planning to the potential areas and school, advertising media that will be used, monitoring of students' academic status, evaluation and planning of students' study plans, and performance evaluation of study program within the aspects of alumni quality and length of study. In addition, this research also result the application of data mining for finding the rules that used to driving and directing the students enthusiast and study program selection for prospective new students

    Data warehouses have been developed to answer the increasing demands of quality information required by the top managers and economic analysts of organizations. Their importance in now a day business area is unanimous recognized, being the foundation for developing business intelligence systems. Data warehouses offer support for decision-making process, allowing complex analyses which cannot be properly achieved from operational systems. This paper presents the ways in which a data warehouse may be developed and the stages of building it.data warehouse, data mart, data integration, database management system, OLAP, data mining

    A case study of predicting banking customers behaviour by using data mining

    Data Mining (DM) is a technique that examines information stored in large database or data warehouse and find the patterns or trends in the data that are not yet known or suspected. DM techniques have been applied to a variety of different domains including Customer Relationship Management CRM). In this research, a new Customer Knowledge Management (CKM) framework based on data mining is proposed. The proposed data mining framework in this study manages relationships between banking organizations and their customers. Two typical data mining techniques - Neural Network and Association Rules - are applied to predict the behavior of customers and to increase the decision-making processes for recalling valued customers in banking industries. The experiments on the real world dataset are conducted and the different metrics are used to evaluate the performances of the two data mining models. The results indicate that the Neural Network model achieves better accuracy but takes longer time to train the model

    The topics of data warehousing and data mining encompasses architectures, algorithms and tools for bringing together selected data from multiple databases or other information sources into a single repository called a data warehouse which is suitable for direct querying or analysis. The querying and analysis can be implemented with any of the data mining tools being developed. Data mining is the non-trivial extraction of implicit, previously unknown and potentially useful information from information sources; In this thesis, we will define a specific data warehousing architecture, its components and give an explanation of the responsibilities of the components in the data warehousing system are defined. The new data warehousing system and it components will also provide suitable topics for exploratory research into their implementation. We will also explain how data mining techniques will be used to extract data from multiple information sources to place data into the central data warehouse of the system and how data mining tools will be used to query and analysis the data warehouse system
