...3) Abstract Data is the most valuable enterprise asset, and a properly integrated data management strategy will enhance an organization’s ability to develop valuable insights that will provide greater business value. More specifically, data management is the development and execution of a company’s procedures, policies and architectures: in order to better manage its informational needs in an effective and efficient manner. Data warehousing, online transactional databases, and data mining can solve or reduce difficulties associated with managing data. Solving Data Management Difficulties The concept of data warehousing is to create a central location and permanent storage space for the various data sources needed to support a company’s analysis and reporting. In other words, it is a database that focuses on query and analysis rather than actual transaction processing (Reeves, 2009). It usually contains historical data derived from a company’s transaction data, but may include data from several other sources. Data warehouses separate analysis workload from transaction workload and enable an organization to consolidate data from several sources. Since executives and managers can quickly and efficiently access data from a multiple sources, they are able to make informed decisions on key initiatives promptly: rather than waste time retrieving data from multiple sources. Another benefit of data warehousing is that it stores large amounts of historical data so it can be analyzed...

Assignment 4: Data Mining Webopedia (2013) defines data mining as, "A class of database applications that look for hidden patterns in a group of data that can be used to predict future behavior. For example, data mining software can help retail companies find customers with common interests." This means that large groups of data that is derived by information obtained through customers, customer purchases and customer buying habits. Businesses use this information for a variety of reasons; it is used for purchasing merchandise, tracking how certain merchandise is selling and even customers buying habits. Webopedia goes on to state that "data mining is popular in the science and mathematical fields but also is utilized increasingly by marketers trying to distill useful consumer data from Web sites." Predictive analytics are used to understand customer's behaviors, according to the article Predictive Analytics with Data Mining: How It Works (Siegel, Feb. 2005) it describes how this method has a predictor. This is "a single value measured for each customer" this is based on the customers purchased over a period and sets higher values for the most recent customer purchases. The...

...Data Mining Nabeel Ahmed University of Northern Virginia Abstract ‘The vein of research data is almost always richer than it appears to be on the surface, but it can only be of value if mined.—Morris Rosenberg’ (AGOSTA, 2000) Recent years, Data Mining has become hot topic of enterprises. More and more companies intend to introduce data mining techniques. One report from the United States treats data mining as one of the ten favorable fields in the 21st century, of which by means shows its importance. Generally speaking, data mining are often applied in those fields, such as insurance and finance industries, retailing and direct marketing industries, communication industry, manufacturing industry and Medical service industry, etc. The data related to management decision making has been accumulating surprisingly quickly because of the improvement in high technology. As the byproduct of internet, e-commerce, e-banking, pos system, barcode scanner and intelligent robot, the acquirement of electronic data has already become cheap and existing everywhere. These data are normally stored in data warehouse and data marts to provide assistance for management decision-making. Data mining is a fast growing field, its main target is to develop some techniques to assist the managers in intelligent analyzing and utilizing mass data. Data mining was already being reported in successfully utilized in the aspects of credit rating, fraud detection, database marketing, customer relationship...

...Running Head: DATA MINING Assignment 4: Data Mining Submitted by: Submitted to: Course: Introduction Data Mining is also called as Knowledge Discovery in Databases (KDD). It is a powerful technology which has great potential in helping companies to focus on the most important information they have in their data base. Due to the increased use of technologies, interest in data mining has increased speedily. Data mining can be used to predict future behavior rather than focus on past events. This is done by focusing on existing information that may be stored in their data warehouse or information warehouse. Companies are now utilizing data mining techniques to assess their database for trends, relationships, and outcomes to improve their overall operations and discover new ways that may permit them to improve their customer services. Data mining provides multiple benefits to government, businesses, society as well as individual persons (Data Mining, 2011). Benefits of data mining to the businesses when employing Advantages of data mining from business point of view is that large sizes of apparently pointless information have been filtered into important and valuable business information to the company, which could be stored in data warehouses. While in the past, the responsibility was on marketing utilities and services, products, the center of attention is now on customers- their choices, preferences, dislikes and likes, and possibly data mining is one of the most important tools...

I also certify that I have never submitted the idea and product of this Project for academic or employment credits. XIAO Jiali, Jenny (0830300038) Date: ii Application of Bootstrap method in spectrometric data analysis XIAO Jiali, Jenny Science and Technology Division Abstract In this project the bootstrap methodology for spectrometric data is considered. The bootstrap can also compare two populations, without the normality condition and without the restriction to comparison of means. The most important new idea is that bootstrap resampling must mimic the separate samples design that produced the original data. Bootstrap in mean, bootstrap in median, and bootstrap in confidence interval are three kinds of effective way to handle mass spectrometric data. Then,we need to reduce dimension based on bootstrap method. It may allow the data to be more easily visualized. Afterwards, using results obtained by bootstrap, we use data mining method to predict a patient has ovarian cancer or not. Decision tree induction and neural network are usual way to classify it. Keywords: Bootstrap, data mining...

...ADVANCES BUSINESS ANALISIS Introduction : We can answers to what happene,d why, what is happening. But difficlut to answer what will happen ? and we can often discover uncexpected connection in the business ! Data mining is defi ned as “the nontrivial extraction of implicit, previously unknown, and potentially useful information (patterns) from data.” This is called knowledge discovery. The most important thing is to identify the patterns, whcich allow us to deine the structure ; We can say tjat data mining gives us knowledge. The most common application of data mining are : classification, prediction, cluster analisis (objetcs that have similars featurs) , mining association rules 1) Classification : trees Ex : the decision to grant credit How you construct a classifier : learning on the basis of learning eexamples (examples of correctly categorized objects) it gives us learning system (algorytms) and then classifier. Limitations : To construct a classifi er on the basis of a set of examples, you need to solve many problems that are common for the majority of data-mining algorithms. However, if you are aware of these limitations, you should have reasonable expectations regarding their possible applications and the quality of the knowledge generated by them. The main problems are connected with induction, history, updating, and overfi tting : * Induction problem : learning from examples is inductive reasoning : so we make generalizacion, from limited observation...

...What Is Data Mining? Data mining is the practice of automatically searching large stores of data to discover patterns and trends that go beyond simple analysis. Data mining uses sophisticated mathematical algorithms to segment the data and evaluate the probability of future events. Data mining is also known as Knowledge Discovery in Data (KDD). The key properties of data mining are: * Automatic discovery of patterns * Prediction of likely outcomes * Creation of actionable information * Focus on large data sets and databases Data mining can answer questions that cannot be addressed through simple query and reporting techniques. Automatic Discovery Data mining is accomplished by building models. A model uses an algorithm to act on a set of data. The notion of automatic discovery refers to the execution of data mining models. Data mining models can be used to mine the data on which they are built, but most types of models are generalizable to new data. The process of applying a model to new data is known as scoring. See Also: Oracle Data Mining Application Developer's Guide for a discussion of scoring and deployment in Oracle Data Mining Prediction Many forms of data mining are predictive. For example, a model might predict income based on education and other demographic factors. Predictions have an associated probability (How likely is this prediction to be true?). Prediction probabilities are also known as confidence (How confident can I be of this prediction...

...Data Mining 0. Abstract With the development of different fields, artificial intelligence, machine learning, statistic, database, pattern recognition and neurocomputing they merge to a newly technology, the data mining. The ultimate goal of data mining is to obtain knowledge from the large database. It helps to discover previously unknown patterns, most of the time it is followed by deeper manual evaluation to explain and correlate the results to establish a new knowledge. It is often practically used by government, bank, insurance company and medical researcher. A general basic idea of data mining would be introduced. In this article, they are divided into four types, predictive modeling, database segmentation, link analysis and deviation detection. A brief introduction will explain the variation among them. For the next part, current privacy, ethical as well as technical issue regarding data mining will be discussed.

...generally understood as the successful introduction of a new thing or method. They also said “innovation is the embodiment, combination, or synthesis of knowledge in original, relevant, valued new products, processes, or services”. Innovation therefore involves creativity but the two are not the same. The innovation should bring new product, improve quality and enhance customer service. Innovation begins with creative ideas as suggested by Amabile et al (1996) who define innovation as “the successful implementation of creative ideas within an organisation”. Authors like Byrd (2003) formulated equation to differentiate innovation and creativity: Innovation = Creativity * Risk Taking. From the equation there is clear difference between creativity and innovation. In Economic perspective innovation is viewed as introduction of new good, new market, new methods of production, new source of raw materials and new organization of any industry such as monopoly. Schumpeter (1934). The data mining teaching tool to illustrate association to level three students is an innovation because it is a new application which is unique and has not been developed according to the research carried out. A number of data mining software for academic purpose have so been produced according to the research. However teaching tools for level three students to demonstrate association is a new product which will open new market, new methods of teaching data mining, create new industry (monopoly) especially...
