University of Alabama Computer Science 302 Skipwith Ch. D. To create a new data warehouse Which of the following describes a relational database? We can specify a data mining task in the form of a data mining query. Classification sorts items (or individuals) into categories based on a previously learned model. For example, a classification model could be used to identify loan applicants as low, medium, or high credit risks. For example, the business goal might be “Increase catalogue sales to existing customers.” A data mining goal might be “Predict how many widgets a customer will buy, given their purchases over the past three years, demographic information (age, salary, city, etc. Answer: No. Specific course topics include pattern discovery, clustering, text retrieval, text mining and analytics, and data visualization. A goal of data mining includes which of the following? An operational system is which of the following? Cloud computing uses Server virtualization. Data mining is an interdisciplinary subfield of computer science and statistics with an overall goal to extract information (with intelligent methods) from a data set and transform the information into a comprehensible structure for further use. Data scrubbing is which of the following? Clustering involves finding groups with similar characteristics. Data mining is the analysis step of the "knowledge discovery in databases" process, or KDD.

Computer database in which all data is stored in Relations which (to the user) are tables with rows and columns. C. A system that is used to support decision making and is based on current data. 1.Type of arguments 2.Return type of methods 3.Number of arguments 4.Names of methods 5.Order of arguments For example, marketers often use clustering to identify groups and subgroups within their target markets. Data mining algorithms are often sensitive to specific characteristics of the data: outliers (data values that are very different from the typical values in your database), irrelevant columns, columns that vary together (such as age and date of birth), data coding, and data that you choose to include or exclude. 5 points Question 3 In the Influence Health case study, what was the goal of the system? According to the authors, the metaphor of "data mining" captures all of the following EXCEPT: (p. 350) A. A. A. Server virtualization is more for a good reason. The @active data warehouse architecture includes which of the following? To explain some observed event or condition B. An operational system is which of the following? 1. Cloud computing is not suited for situations. Data mining is a process used by companies to turn raw data into useful information. The goal of classification is to accurately predict the target class for each case in the data. 3. First, it is required to understand business objectives clearly and find out what are the business’s needs. The techniques came out of the fields of statistics and artificial intelligence (AI), with a bit of database management thrown into the mix. A data mining goal states project objectives in technical terms. Every table shares at least one field with another table in 'one to one,' 'one to many,' or 'many to many' relationships. These relationships allow the database user to access the data in almost an unlimited number of ways, and to combine the tables as building blocks to create complex and very large databases. Data scientists and analysts use many different data mining techniques to accomplish their goals. Hence, the given statement that 'Cloud computing uses Server virtualization.' Cloud computing is an information technology (IT) paradigm that enables ubiquitous access to shared pools of configurable system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet.
