respond to three separate prompts but prepare your paper as one research paper. Be sure to include at least one UC library source per prompt, in addition to your textbook (which means you'll have at least 4 sources cited).  Start your paper with an introductory paragraph. Prompt 1 "Data Warehouse Architecture" (2-3 pages): Explain the major components of a data warehouse architecture, including the various forms of data transformations needed to prepare data for a data warehouse. Also, describe in your own words current key trends in data warehousing.  Prompt 2 "Big Data" (1-2 pages): Describe your understanding of big data and give an example of how you’ve seen big data used either personally or professionally. In your view, what demands is big data placing on organizations and data management technology?  Prompt 3 “Green Computing” (1-2 pages):  One of our topics in Chapter 13 surrounds IT Green Computing. The need for green computing is becoming more obvious considering the amount of power needed to drive our computers, servers, routers, switches, and data centers. Discuss ways in which organizations can make their data centers “green”. In your discussion, find an example of an organization that has already implemented IT green computing strategies successfully.  

Discussion 1 (Chapter 10): There have been many books and opinion pieces written about the impact of AI on jobs and ideas for societal responses to address the issues. Two ideas were mentioned in the chapter – UBI and SIS. What are the pros and cons of these ideas? How would these be implemented?Discussion 2 (Chapter 11): Explain how GDSS can increase some benefits of collaboration and decision making in groups and eliminate or reduce some losses.Your response should be 250-300 words. Respond to two postings provided by your classmates.There must be at least one APA formatted reference (and APA in-text citation) to support the thoughts in the post. Do not use direct quotes, rather rephrase the author's words and continue to use in-text citations.

Assignment 1: The CEO’s ChallengeDue Week 3 and worth 150 points You’ve just left an all-hands meeting at your company*. The CEO was very upset at the rise of shadow IT projects – a major indicator that the company’s internal information system has failed to meet its needs. Because the current information system is inadequate, inefficient, and outdated, the CEO is inviting everyone in the organization to propose a new operational, decision support, or enterprise information system to replace it. The executives have allocated $5 million to fund the most promising idea. This is your chance to make a difference in the company (not to mention your own career). Write your proposal as a memo that the entire C-suite will review. Include at least these points, in your own words, to be persuasive: Identify the main functions of your proposed information system and why they are important to the business. Describe what types of data your information system will hold and how data quality will be ensured. Explain how the old information system handles the functions you mentioned, the problems that occur, and why your information system will handle things better. Offer evidence of feasibility: Show that similar information systems have been built successfully and that they save more money than they cost. The executives are busy, so keep your memo to 1-4 pages and avoid any extraneous content. *You may use a current or former employer, but do not disclose anything confidential. Or, you can pick another organization if you are familiar with their internal (not customer-facing) information systems. You can disguise the organization and populate it with famous names. Made-up companies are problematic because of the amount of detail and realism they require.
