Within the Discussion Board area, write 400–600 words that respond to the following questions with your thoughts, ideas, and comments. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas.Knowledge (analytics), information (reporting), and facts (data) form the basis of business intelligence (BI). Although many service organizations (nonprofits) are developing core competencies in one or more of these key areas, it takes a true organization-wide commitment and approach to achieve the benefits of business intelligence and data-driven decision making.A rapidly-growing service organization (e.g., a nonprofit organization) has hired you as a consultant. Your task is to build a data warehouse and the foundational aspects of its BI program. You have your first meeting with the head of the service organization, and you must discuss the following topics (as well as provide examples to support your explanations):Explain the theoretical framework behind the effort of building a data warehouse and establishing the foundations for a BI program. Make sure your response describes the framework that you found in your research.Explain how the data warehousing process can be a driving force behind the organization’s new BI program.Your response should be 400–600 words, plus sources, and repeating the questions does not count toward the total word count.

Include a brief description of the organization’s information security issues in areas of network management, server management, Web and non-Web applications, data management, and cloud computing.Detect and contain attacks on platform based application products.Differentiate attacks based on networked interfaces to relational databases.Evaluate emerging technology driven applications potential security risks and formulate prevention strategiesIdentify and remediate security vulnerabilities attributable to Web-based scripting languages.

Assignment DescriptionManagement is worried, after consulting with the IT department that the current documentation of the present architecture was not done correctly and with the required details, therefore if IoT is implemented they desire more detailed graphical documentation on its implementation. Provide the following components as part of an architecture model graphic to be delivered to management for the asset tracking system:Provide an introduction to the paper concerning the purpose of the graphic and the overall solution being recommended by the asset tracking IoT implementation (2-3 paragraphs).Provide descriptive information regarding the architectural model graphic, and the details describing the devices, applications, Cloud/Server environment and gateway. (2 pages)Provide the architectural graphic with the components below (Describe each of the objects on the diagram below, the interconnections or interfaces, types of data traveling across the connections, active protocols, cabling or wireless connections, and implemented security):Devices (Generic device – Sensing and Actuating Devices)IoT Application (transforms the data for value to the user)Cloud/Server (data storage, processing and management)Gateway capability (data is acquired, forwarded to the communications network)Provide a conclusion to the paper summarizing the content and purpose of the paper.

Your company develops a variety of web-based products. Many tools for transforming HTML (the language of web pages) require those pages to be written in a “disciplined” dialect of HTML called XHTML. One of the key factors distinguishing XHTML from ordinary HTML is that all opening and closing tags in XHTML must be properly balanced.Write a validator that can examine an XHTML file for this balancing.

**DISCUSSION POST**Networks have changed drastically over the last 30 years. With the first introduction of the 56k modem, which was about 3 typewriter pages per second, to speeds well over 1Gbps these days, the ability to use networks globally, has changed the way we do business. Using research, determine where networks will go in the next 5-10 years and how that might impact the global economy.

ITS-632 Intro to Data MiningDr. Steven CaseDept. of Information Technology &School of Computer and Information SciencesUniversity of the CumberlandsChapter 3 Assignment[Your Name Here]1. Obtain one of the data sets available at the UCI Machine Learning Repository and apply as many of the different visualization techniques described in the chapter as possible. The bibliographic notes and book Web site provide pointers to visualization software.2. Identify at least two advantages and two disadvantages of using color to visually represent information.3. What are the arrangement issues that arise with respect to three-dimensional plots?4. Discuss the advantages and disadvantages of using sampling to reduce the number of data objects that need to be displayed. Would simple random sampling (without replacement) be a good approach to sampling? Why or why not?5. Describe how you would create visualizations to display information that de-scribes the following types of systems.a) Computer networks. Be sure to include both the static aspects of the network, such as connectivity, and the dynamic aspects, such as tra?c.b) The distribution of speci?c plant and animal species around the world fora speci?c moment in time.c) The use of computer resources, such as processor time, main memory, and disk, for a set of benchmark database programs.d) The change in occupation of workers in a particular country over the last thirty years. Assume that you have yearly information about each person that also includes gender and level of education.Be sure to address the following issues:· Representation. How will you map objects, attributes, and relation-ships to visual elements?· Arrangement. Are there any special considerations that need to be taken into account with respect to how visual elements are displayed? Speci?c examples might be the choice of viewpoint, the use of transparency, or the separation of certain groups of objects.· Selection. How will you handle a large number of attributes and data objects6. Describe one advantage and one disadvantage of a stem and leaf plot with respect to a standard histogram.7. How might you address the problem that a histogram depends on the number and location of the bins?8. Describe how a box plot can give information about whether the value of an attribute is symmetrically distributed. What can you say about the symmetry of the distributions of the attributes shown in Figure 3.11?9. Compare sepal length, sepal width, petal length, and petal width, using Figure3.12.10. Comment on the use of a box plot to explore a data set with four attributes: age, weight, height, and income.11. Give a possible explanation as to why most of the values of petal length and width fall in the buckets along the diagonal in Figure 3.9.12. Use Figures 3.14 and 3.15 to identify a characteristic shared by the petal width and petal length attributes.13. Simple line plots, such as that displayed in Figure 2.12 on page 56, which shows two time series, can be used to e?ectively display high-dimensional data. For example, in Figure 2.12 it is easy to tell that the frequencies of the two time series are di?erent. What characteristic of time series allows the e?ective visualization of high-dimensional data?14. Describe the types of situations that produce sparse or dense data cubes. Illustrate with examples other than those used in the book.15. How might you extend the notion of multidimensional data analysis so that the target variable is a qualitative variable? In other words, what sorts of summary statistics or data visualizations would be of interest?16. Construct a data cube from Table 3.14. Is this a dense or sparse data cube? If it is sparse, identify the cells that are empty.17. Discuss the di?erences between dimensionality reduction based on aggregation and dimensionality reduction based on techniques such as PCA and SVD.

The human resource department is updating its HIPAA Basic Training for Privacy and Security course. As a security analyst for the hospital, you have been tasked with covering the topics in the training related to the HIPAA security rule and the information that hospital staff needs to know regarding personally identifiable information (PII), personal health information (PHI), and electronic personal health information (ePHI) to comply with federal regulations.This week, you will submit your presentation. The presentation should include voice overlays as a narrative for each slide. Include one to two slides for each bullet below (4-8 slides total) explaining the following:HIPAA Security RuleHIPAA, PII, PHI, and ePHI DefinitionsSafeguarding of PII, PHI, and ePHIDisclosures of PII, PHI, and ePHIPLEASE READ THE INSTRUCTIONS CAREFULLY AND ANSWER ACCORDINGLY.
