 In chapter 6, the author describes twelve disruptions to existing markets.Choose one of the disruptions discussed in chapter 6, and explain how you think it will impact today’s economy, and provide at least two real examples of the chosen disruption being realized with blockchain technology today.  Then think of three questions you’d like to ask other students.

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” (2-3 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” (2-3 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. Discuss that organization and share your link. You can find examples in the UC Library.

Conclude your paper with a detailed conclusion section. 

The paper needs to be approximately 7-10 pages long, including both a title page and a references page (for a total of 9-12 pages). Be sure to use proper APA formatting and citations to avoid plagiarism.

Your paper should meet the following requirements:

• Be approximately seven to ten pages in length, not including the required cover page and reference page.

• Follow APA7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.

• Support your answers with the readings from the course, the course textbook, and at least three scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. The UC Library is a great place to find supplemental resources.

• Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.

Discuss in 500 words or more federated architecture in cloud systems. Remember that this is a cloud class not a database class. 

Use at least three sources. Do Use Google. Include at least 3 quotes from your sources enclosed in quotation marks and cited in-line by reference to your reference list.  Example: “words you copied” (citation) These quotes should be one full sentence not altered or paraphrased. Cite your sources using APA format. Use the quotes in your paragaphs.  Stand alone quotes will not count toward the 3 required quotes.

Background: Kamehameha Institute is an organization that provides educational offerings to non-traditional students. The organization has tailored its unique educational offerings into the groups shown in Table 1 below:

Table 1. Kamehameha Educational Offerings.

GroupOfferingKamehameha BrandedFocused on the general public/provides services directly to its studentsCo-BrandedProvides the same services as Kamehameha Branded but resold by a third party and labeled as “…. Kamehameha Strong”White Label BrandedWhile the service offering is the same, these services are labeled solely with the third parties’ information

The State of Hawai’i regulates the educational sector, driving the need to ensure Kamehameha follows the State’s strict security and regulatory requirements. Kamehameha’s leadership is also very concerned with the threat posed by the online theft of their unique intellectual property. Additionally, the number of Hawai’ian entities breached by threat actors is on the rise. Thus, security, privacy, and compliance are all important considerations for the Kamehameha network architecture.

Your boss, the Kamehameha Institute’s Chief Operating Officer (COO) has tasked you to design a network infrastructure for three facilities located in the Hawaiian Islands of Honolulu, Hilo, and Lihue. The COO stipulated that you must separate the three group offerings in Table 1 and provide for strengthened defenses to protect Kamehameha’s cultural heritage. After meeting with the COO, the two of you drafted the following set of requirements for your network design:

· Each of the facilities has three floors:

· The first and second floor of each building requires 150 network connections each

· The third floor of each building houses a data center and requires 75 network connections

· The Honolulu location requires additional network connections for failover purposes

· The Hilo location will be the primary data center and house redundant database servers

· The Lihue location will serve as a failover data center and house the primary web servers (including the primary application and primary database servers)

· A constant connection between the three locations, carrying at least 75 Mbps of data

· All servers at all locations must have redundancy

· Protection from intrusions is required and should be documented

· A plan to verify security and failover measures is required

· Submission: Using the free tool, daw.io available at https://draw.io (no sign-in or registration required), create a network diagram (drawing) specific to the organization that encompasses the three facilities and also depicts ant necessary interconnections. Figure 1 shows the draw.io ‘new network diagram’ dialog window:

Figure 1. Draw.io New File Dialog Showing the Network Diagramming Templates

Your diagram should include enough detail to show the topology interconnections. The viewer should be able to understand the Kamehameha Institute’s network environment and be able to implement the architecture you develop. Ensure that you properly cite any external sources.

One of the keys to producing a viable network diagram is labeling the objects consistently and descriptively. Think about what you would want to know about a network device if you logged into it with little prior information. Consider location, floor number, or other pertinent information. At a minimum, include the following elements:

· IMPORTANT: Your network diagram must include an identifying label (e.g., callout box) that includes your class and section, assignment title, your name, and the date. Edit the items in italics. Your assignment will not be accepted if this element is missing:

· Any necessary hardware

· Site-to-Site (WAN) connections (e.g., leased line connectivity, satellite, etc.)

· Annotate the following values for each of the Sites:

· Network ID

· Useable Range

· Subnet Mask

· CIDR Value

· Broadcast Address

· All devices require hostnames complying with the following naming conventions:

· Routers: Rx; where x is the site number incremented by a value of 1 for each router

· Switches: Sx; where x is the site number incremented by a value of 1 for each switch

· Servers: SRVx where x is the server number incremented by a value of 1 for each server

· For each site router, implement a private ip addressing scheme using a range suitable for corporate infrastructure and include the following:

· management vlan

· production vlan

High availability

When finished, export the diagram as a PDF document (Note: You will need to use this diagram again in Project 3, so ensure you save the xml source file!) and submit it to the Assignment folder. Figure 2 demonstrates how to export your draw.io diagram as a PDF document:

Risk management is one of the most important components in empowering an organization to achieve its ultimate vision. With proper risk management culture and knowledge, team members will be “speaking” the same language, and they will leverage common analytical abilities to identify and mitigate potential risks as well as exploit opportunities in a timely fashion. In order to consolidate efforts, the existence of an integrated framework is crucial. 

This is why an ERM is necessary to the fulfillment of any organization’s goals and objectives. In your final research project for the course, your task is to write a 7-10 page paper discussing the following concepts:

• Introduction – What is an ERM?
• Why Should an Organization Implement an ERM Application?
• What are some Key Challenges and Solutions to Implementing an ERM?
• What is Important for an Effective ERM?
• Discuss at least one real organization that has been effective with implementing an ERM framework/application.
• Conclusion – Final thoughts/future research/recommendation

BACKGROUND: A shell provides a command-line interface for users. It interprets user commands and executes them. Some shells provide simple scripting terms, such as if or while, and allow users to make a program that facilitates their computing environment. Under the hood, a shell is just another user program as you know from Minor2 assignment. The file /bin/bash is an executable program file for the bash shell. The only thing special about your login shell is that it is listed in your login record so that /bin/login (i.e., the program that prompts you for your password) knows what program to start when you log in. If you run “cat /etc/passwd”, you will see the login records of the machine.

PROGRAM DESCRIPTION

GROUP COLLABORATIVE PORTION: In this assignment, you will implement the shell “engine” as the group component, where all members are responsible for the following functionality.

A Command-Line Interpreter, or Shell

Your shell should read the line from standard input (i.e., interactive mode) or a file (i.e., batch mode), parse the line with command and arguments, execute the command with arguments, and then prompt for more input (i.e., the shell prompt) when it has finished. This is what Minor 2 program should do with addition of batch processing which means just reading a batch line by line and calling the same interpretation logic.

1. Batch Mode

In batch mode, your shell is started by specifying a batch file on its command line. The batch file contains the list of commands that should be executed. In batch mode, you should not display a prompt, but you should echo each line you read from the batch file back to the user before executing it. After a batch is finished the shell will exit.

1. Interactive Mode

No parameters specified on command line when the shell is started. In this mode, you will display a prompt (any string of your choice) and the user of the shell will type in a command at the prompt.

You will need to use the fork() and exec() family of system calls. You may not use the system() system call as it simply invokes the system’s /bin/bash shell to do all of the work. You may assume that arguments are separated by whitespace. You do not have to deal with special characters such as ‘, “, , etc. You may assume that the command-line a user types is no longer than 512 bytes (including the ‘n’), but you should not assume that there is any restriction on the number of arguments to a given command.

INDIVIDUAL PORTIONS

Build-in Commands: Every shell needs to support a number of built-in commands, which are functions in the shell itself, not external programs. Shells directly make system calls to execute built-in commands, instead of forking a child process to handle them.

In this assignment, each member of the group will implement one of the following section and commit in GitLab the code that supports those commands:

1. Add a new built-in alias command that allows you to define a shortcut for commands by essentially defining a new command that substitutes a given string for some command, perhaps with various flags/options. The syntax is as follows: alias alias_name=’command’. For example, you can define an alias with alias ll=’ls –al’, so that the user can then enter ll at the prompt to execute the ls -al command. Specifying alias with no arguments should display a list of all existing aliases. You may remove a single alias with the command alias -r alias_name or all defined aliases with alias -c.
2. Add a new built-in exit command that exits from your shell with the exit() system call. Also add support for signal handling and terminal control (Ctrl-C, Ctrl-Z). You do not want those signals to terminate your shell. Instead you need to handle them and terminate processes that your shell started if any. Be aware that forked processes will inherit the signal handlers of the original process.
3. Add a new built-in path command that allows users to show the current pathname list. The initial value of path within your shell will be the pathname list contained in the PATH environment variable. path + ./dir appends the ./dir to the path variable. You may assume that only one pathname is added at a time. You will need to add it to the “real” PATH environment variable for executables in the path to work correctly. path – ./dir removes the pathname from the path variable. You may assume that only one pathname is removed at a time. Also, you need to restore your PATH environment variable to its original state when the user exits your shell.
4. Add a new built-in history command that lists your shell history of previous commands. It is up to you to select what number of prior commands to keep in history. history –c command should clear your history list. history N, where N is number, displays your prior N-th command starting with the last one. history N -e executes your prior N-th command.

OPTIONAL assignments for extra credits:

1. Extend your shell with I/O redirection: <, >, >> (+20%).
2. Extend your shell with pipelining | (+20%).

DEFENSIVE PROGRAMMING (GROUP COLLABORATIVE EFFORT): Check the return values of all system calls utilizing system resources. Do not blindly assume all requests for memory will succeed and that all writes to a file will occur correctly. Your code should handle errors properly. In general, there should be no circumstances in which your C program will core dump, hang indefinitely, or prematurely terminate. Therefore, your program must respond to all input by printing a meaningful error message and either continue processing or exit, depending upon the situation. Many questions about functions and system behavior can be found in the manual pages. You should handle the following situations:

• An incorrect number of command line arguments to your shell program;
• The batch file does not exist or cannot be opened.
• A command does not exist or cannot be executed.
• A very long command line (over 512 characters including the ‘n’).

REQUIREMENTS: Your code must be written in C.

GRADING: Your C program file(s), README, and makefile shall be committed to our GitLab environment as follows:

• Your C program file(s). Your code should be well documented in terms of comments. For example, good comments in general consist of a header (with your name, course section, date, and brief description), comments for each variable, and commented blocks of code.
• A README file with some basic documentation about your code. This file should contain the following four components:

Your name(s);

Organization of the Project. Since there are multiple components in this project, you will describe how the work was organized and managed, including which team members were responsible for what components – there are lots of ways to do this, so your team needs to come up with the best way that works based on your team’s strengths. Note that this may be used in assessment of grades for this project.

Design Overview: A few paragraphs describing the overall structure of your code and any important structures.

Known Bugs or Problems: A list of any features that you did not implement or that you know are not working correctly.

• A Makefile for compiling your source code, including a clean directive.
• Your program will be graded based largely on whether it works correctly on the CSE machines.

1. Design a flowchart and pseudocode for insurance subscription plan. Allow user to enter number of years and the plan price. Assume that the user earns four percent discount every year. Program output is a schedule that lists each year number in insurance subscription plan starting with year 0 and the user’s savings at the start of that year.  

Example: user entered 3 years insurance subscription for 120 KD plan. The program should output:

Year number 0 the discount percentage is 0% and the discount amount is 0KD

Year number 1 the discount percentage is 4% and the discount amount is 4.8KD

Year number 2 the discount percentage is 8% and the discount amount is 9.6KD

Year number 3 the discount percentage is 12% and the discount amount is 14.4KD
