...is meant by management information systems (MIS). Include in your answer one example of how an MIS can be used. * Management information system, or MIS, broadly refers to a computer-based system that provides managers with the tools to organize, evaluate and efficiently manage departments within an organization. In order to provide past, present and prediction information, a management information system can include software that helps in decision making, data resources such as databases, the hardware resources of a system, decision support systems, people management and project management applications and any computerized processes that enable the department to run efficiently. The role of the management information system (MIS) manager is to focus on the organization’s information and technology systems. The MIS manager typically analyses business problems and then designs and maintains computer applications to solve the organization’s problems. B) Describe the factors which make a good or poor MIS using example to illustrate your answer. * A good MIS is a computer system that supplies the information in a form that managers can easily understand and use that allow them to make good business decision. Such information can reduce the risk in making decision. * A good MIS is fast because managers do not want to wait too long for the information to be displayed. * The information from the MIS must be relevant so they do not have to wade...

...Quantitative Association Rule Mining Using Information-Theoretic Approach Mary Minge University of Computer Studies, Lashio dimennyaung@gmail.com Abstract Quantitative Association Rule (QAR) mining has been recognized an influential research problem due to the popularity of quantitative databases and the usefulness of association rules in real life. Unlike Boolean Association Rules (BARs), which only consider boolean attributes, QARs consist of quantitative attributes which contain much richer information than the boolean attributes. To develop a data mining system for huge database composed of numerical and categorical attributes, there exists necessary process to decide valid quantization of the numerical attributes. One of the main problems is to obtain interesting rules from continuous numeric attributes. In this paper, the Mutual Information between the attributes in a quantitative database is described and normalization on the Mutual Information to make it applicable in the context of QAR mining is devised. It deals with the problem of discretizing continuous data in order to discover a number of high confident association rules, which cover a high percentage of examples in the data set. Then a Mutual Information graph (MI graph), whose edges are attribute pairs that have normalized Mutual Information no less than a predefined information threshold is constructed. The cliques in the MI graph represent a majority of the frequent itemsets. Keywords: Quantitative...

...Chapter 6 Case I Interactive Session : Technology WHAT CAN BUSINESSES LEARN FROM TEXT MINING 1. What challenges does the increase in unstructured data present for businesses? Text mining enables many companies to respond to their customers satisfaction surveys, and web mining enables many web search engines to facilitate collecting data that people need to be more profitable. Now, a huge amount of unstructured data is distributed by these systems. A manager is able to use this system and make an accurate decision for unprecedented cases. information Business intelligence tools deal primarily with data that have been structured in databases and files. However, unstructured data, mostly the kind of data we generate in e-mails, phone conversations, blog postings, online customer surveys, and tweets are all valuable for finding patterns and trends that will help employees make better business decisions. Text mining tools are now available to help businesses analyze these data. These tools are able to extract key elements from large unstructured data sets, discover patterns and relationships, and summarize the information. Businesses might turn to text mining to analyze transcripts of calls to customer service centers to identify major service and repair issues. 2. How does text-mining improve decision-making? Text mining system enables airlines to rapidly extract customer sentiments, preferences, and requests for example, when the airlines suffered from unprecedented...

...New Frontier: Data Analytics Phylicia Marie Phillips Professor Progress Mtshali, Ph. D. Information Systems Decision-Making April 17, 2016 In the past, analytics was reserved for back-room debates by data geeks producing monthly reports on how things are going. Today, analytics make a difference in how a company does business, day to day, and even minute by minute; more specifically how Walmart does business. As many know, Walmart is an American based multinational retail corporation that operates a chain of hypermarkets, grocery stores and discount stores. With over eleven thousand stores and clubs in 27 countries, information technology and data analytics play a major role in Walmart’s survival and helps maintain its competitive advantage. Data Analytics Overview The business intelligence and analytic technologies and applications currently adopted in industry can be considered as BI&A 1.0, where data are mostly structured, collected by companies through various legacy systems, and often stored in commercial relational database management systems (Bottles and Begoli, 2014). The analytical techniques most commonly used in these systems, popularized in the 1990s, are mainly grounded in statistical methods developed in the 1970s and data mining techniques developed in the 1980s (Chiang, 2012). The digitalization of information has created more data and the development of cloud computing, and faster and faster computers has made the increased data more accessible...

...Starbucks Brian Duffey 12/9/2012 MIS 642 Starbucks is a very well known company nowadays. They are very popular and not only bring coffee to people with a plethora of locations, but also have been able to create atmospheres at each location where people can go to get work done, unwind, and even socialize. However, this was not always the case. Back in 1971, Starbucks first opened its doors in the state of Seattle. At this time, they were simply a basic coffeehouse with no intention of turning into a powerful chain. However, eleven years later, Howard Schultz took over as director of retail operations, which is when the expansion first began in the form of selling coffee directly to restaurants and espresso bars. Shortly after this, Starbucks began testing a coffeehouse culture as seen in Milan. This was a success and helped to spur the beginning of Starbucks explosion, first expanding into Chicago and Vancouver, with a total of nearly eighteen thousand stores as of this previous summer. While Starbucks began as a simple place to get coffee, nowadays it is anything but. Stores now offer free Wi-Fi for its customers, and the menu ranges far beyond simple coffee from juices and solid meals, to CDs and other goods that a coffeehouse wouldn’t necessarily be expected to sell. Yet, it all works and has come to be known as synonymous with Starbucks brand and image. When Starbucks first began, there wasn’t much need for business intelligence. Other than attracting...

Yen a,∗ a Department of DSC & MIS, Miami University, Oxford, OH, USA b Department of Information Management, National Chung-Cheng University, Taiwan, ROC Abstract Advancements in technology have made relationship marketing a reality in recent years. Technologies such as data warehousing, data mining, and campaign management software have made customer relationship management a new area where firms can gain a competitive advantage. Particularly through data mining—the extraction of hidden predictive information from large databases—organizations can identify valuable customers, predict future behaviors, and enable firms to make proactive, knowledge-driven decisions. The automated, future-ori- ented analyses made possible by data mining move beyond the analyses of past events typically provided by history-oriented tools such as decision support systems. Data mining tools answer business questions that in the past were too time-consuming to pursue. Yet, it is the answers to these questions make customer relationship management possible. Various techniques exist among data mining software, each with their own advantages and challenges for different types of applications. A particular dichotomy exists between neural networks and chi-square automated interaction detection (CHAID). While differing approaches abound in the realm of data mining, the...
