Student Records Data Design

A prestigious university has recently implemented a consolidation strategy that will require it to centralize their student records. In order to move forward, the local university will need to develop a data model that will retain student records and perform various data extract transform and load (ETL) processes. Imagine that you have been hired as a database consultant to assist in the development of a data design strategy for the student records.

You met with various university subject matter experts and have determined the following after performing various business analysis processes:

Faculty groups are divided by core competencies that the university offers. For example, there are groups such as the art faculty, computer technology faculty, language faculty, and science faculty. Each faculty member has an assigned dean and is designated to teach at one particular campus and school. They are able to teach as many courses as required.
Courses are categorized by course code and title. Certain courses have prerequisites and the university has asked for this to be cataloged as well.
There are various schools within each campus. For example, the Los Angeles campus holds the following schools: School of Science, School of Law, and School of Computer Technology. Additionally, each school offers different professional study programs, such as Forensic Computer Science, Marine Biology, Business Management, and Civil Engineering, to name a few.
The study path for students requires that they be enrolled in a specific professional study program. The professional study program requires the students to complete a specific set of core courses. The university also requires that an online grade book be available. The online grade book should show grades awarded to students for specific courses and the term they completed the course.
The university identifies each student by their name, date of birth, social, and professional study program.

Instructions

Student Records Data Design

Using these findings, write a 3–4 page paper in which you:

Analyze the university’s requirements and provide a proposal to organize all the required data elements. The proposal should include the following:
- Provide an entity relationship model (ERM) that will describe the data structure that will store all data elements. Note: The graphically depicted solution is not included in the required page length.
- Describe any assumptions or limitations for each relationship. For example, professors are able to teach more than one course, or students can only be enrolled in one program.
Create the primary key and foreign keys using a UML class diagram for each table.
Suggest at least four types of business intelligence reports that could help the university in course management, student enrollment, or historical tracking. Support your answer by providing specific business functions that these reports could be used for to assist executives of the university.
Consider outsourcing the functions above as an alternative for development of the database. Research the Internet and other media sources for vendors who develop registrar and school management database systems.
- Suggest three vendors that developed and are employing efficient registrar and school management database systems and support your reasons to choose from one of these three vendors.
- Compare and contrast the key aspects that each system offers. Examples of system aspects include but are not limited to cloud based, pricing model, open source, et cetera.
Go to the Strayer Library to locate at least three quality resources in this assignment. Note: Wikipedia and similar websites do not qualify as quality resources.
The cover page and the reference page are not included in the required assignment page length. Include charts or diagrams created in any chart or drawing tool with which you are familiar. The completed diagrams or charts must be imported into the Word document before the paper is submitted.

This course requires the use of Strayer Writing Standards (SWS). The library is your home for SWS assistance, including citations and formatting. Please refer to the Library site for all supports. Check with your professor for any additional instructions.

The specific course learning outcome associated with this assignment is:

NIMS Disaster Response Impact

By Academic Wizard Blog

NIMS Disaster Response Impact

Response to natural and man-made disasters have changed quite significantly since the implementation of the National Incident Management System (NIMS). Provide an example of a recent natural disaster or terrorist attack that has occurred in your region in the last 10 years. In what ways do you think the implementation of NIMS shaped the responding organization’s response? What component of NIMS do you believe was the most helpful in the response to the incident you identified? Explain your rationale.

NIMS Disaster Response Impact

If you do not currently live in the United States, you may choose an incident in an area you have a connection to or one on which you are most informed.

TEXTBOOK

Oliver, W. M., Marion, N. E., & Hill, J. B. (2021). Introduction to homeland security: Policy, organization, and administration (2nd ed.). Jones & Bartlett Learning. https://online.vitalsource.com/#/books/9781284205213

NIMS Disaster Response Impact

What is an example of a recent natural disaster or terrorist attack in your region?
How did NIMS shape the responding organization’s response?
Which NIMS component was most helpful in the incident?
What is your rationale for selecting that component?
How has disaster response changed due to NIMS?

✅ Comprehensive General Response:

Example Incident: Hurricane Harvey (Texas, 2017)

Hurricane Harvey was one of the most devastating natural disasters in recent U.S. history, particularly impacting the Houston metropolitan area. With over 40 inches of rain in some regions, it caused massive flooding, displaced tens of thousands, and strained emergency response systems at every level of government.

NIMS Influence on Response Efforts:

The implementation of the National Incident Management System (NIMS) had a significant impact on the efficiency and coordination of the Hurricane Harvey response. NIMS provided a standardized framework that allowed federal, state, local, and nonprofit agencies to work collaboratively under a shared structure. This ensured:

Clear communication between agencies
Defined roles and responsibilities
Scalable response efforts that could adjust as the situation evolved
Streamlined resource sharing and logistics support

Without NIMS, the disaster response would likely have been fragmented and less effective, especially given the scale and complexity of the incident.

Most Helpful NIMS Component: Unified Command (Part of ICS)

The Unified Command aspect of the Incident Command System (ICS) was arguably the most valuable component of NIMS during Hurricane Harvey. This allowed multiple agencies—including FEMA, Texas Emergency Management, the National Guard, local law enforcement, and nonprofit organizations like the Red Cross—to operate under a single, coordinated command structure while retaining their own authority and expertise.

Rationale:

Unified Command was essential because:

It minimized confusion about who was in charge of what.
It ensured consistent messaging to the public.
It helped prioritize life-saving efforts, resource allocation, and evacuation protocols.

In a situation where many jurisdictions and disciplines were involved, this shared structure facilitated rapid decision-making and reduced redundancy in operations.

How NIMS Changed Disaster Response:

Since its implementation, NIMS has transformed emergency response in several ways:

Promoted interoperability across agencies.,
Enabled faster mobilization of resources and personnel.,
Introduced standardized training and terminology.,
Reduced bureaucratic delays by defining protocols in advance.

The case of Hurricane Harvey demonstrated that coordinated, well-practiced emergency frameworks can significantly reduce harm and save lives—even in large-scale disasters.

Security Incident Analysis

By Academic Wizard Blog

Security Incident Analysis

To be proactive, organizations need to have structures, processes, and plans in place to counter and respond to potential attacks and to deal with the consequences of successful attacks. A suitable security management plan and well-defined security goals that support the overall goals of the organization can ensure a reasonable level of business continuity, even in the case of security incidents.

In any organization, the individuals on the IT staff must work together to support the security goals of the organization. These individuals play significant roles in detecting and preventing security incidents before they occur. In the case of successful attacks, security management professionals are tasked with acting quickly to mitigate the attack’s effects.

In this assessment, you will refer to the attached “Case Study” document, which contains details regarding a security incident at a small non-governmental organization (NGO). In part I of this task, you will analyze the security incident and provide specific examples and details from the case study to support your risk assessment. In part II, you will create a plan to effectively address the aftermath of the incident and manage the NGO’s ongoing security risks.

Requirements

Part I: Incident Analysis and Response

A. Determine why the attack on Azumer Water’s infrastructure was successful, including two specific vulnerabilities that allowed the attack to occur. Provide details from the case study to support your claims.

B. Explain how Azumer Water’s operations and data have been compromised in the following areas:

• confidentiality, integrity, and availability

• PII (personally identifiable information) Security Incident Analysis

For two of the claims, support your analysis using an industry-standard framework such as NIST or ISO 27002.

C. Identify a federal regulation this NGO violated, providing a specific example from the case study as evidence of Azumer Water’s noncompliance.

D. Recommend two immediate steps to mitigate the impact of the incident, using specific examples from the case study to justify how these steps would mitigate the impact.

E. Explain how having an incident response plan in place will benefit Azumer Water, using details from the case study to support your explanation.

Part II: Risk Assessment and Management

F. Discuss two processes to increase information assurance levels within the organization and bring Azumer Water into compliance with the violated federal regulation identified in part C.

G. Recommend two technical solutions to counter the remaining effects of the attack in the case study and to prevent future attacks.

H. Recommend an organizational structure for IT and security management, including a logical delineation of roles and adequate coverage of responsibilities, to support the efficient discovery and mitigation of future incidents.

I. Identify two risks from the Azumer Water case study and address each of the following components for both risks:

Note: Refer to the “Risk Determination Template” for support with identifying and categorizing risks.

• threat event (risk management tier, threat event from the case study)

• threat source (type of threat source, threat source from the case study)

• threat source characteristics (capability rating, intent rating, targeting rating)

• relevance Security Incident Analysis

• likelihood of attack initiation

• vulnerabilities and predisposing conditions

• severity rating and pervasiveness rating

• likelihood initiated attack succeeds

• overall likelihood

• level of impact (type of impact, potential impact to the organization from the case study, impact rating)

• risk rating

• Discuss your risk management approach based on these risk categorizations

J. Acknowledge sources, using in-text citations and references, for content that is quoted, paraphrased, or summarized.

K. Demonstrate professional communication in the content and presentation of your submission.

Resurrection Salvation Faith & Reason

By Academic Wizard Blog

Resurrection Salvation Faith & Reason

1) After reading the account of the resurrection of Christ in Luke 24 and in Chapter 6 in The Beginning of Wisdom, express why the resurrection is so important to the Christian worldview.

2) According to the Christian worldview, how does one gain eternal life? Use Bible verses to support your response. How does the Christian concept of the afterlife differ from that concept in other worldviews?

3) Jesus made many absolute statements such as the following:

John 14:6: “I am the way and the truth and the life. No one comes to the Father except through me” (NIV).

Matthew 7:13-14: “Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it. But small is the gate and narrow the road that leads to life, and only a few find it.”

Interacting with these statements and based on Chapter 8 of The Beginning of Wisdom and the topic overview, how would you answer someone who is concerned that Christianity portrays that Jesus is the only way to salvation?

Resurrection Salvation Faith & Reason

4) Many believe naturalism (atheism) emphasizes intellect and reason, while religions emphasize faith. Pope John Paul II made the following profound statement at the beginning of his  Encyclical Letter Fides et Ratio:

“Faith and reason are like two wings on which the human spirit rises to the contemplation of truth; and God has placed in the human heart a desire to know the truth – in a word, to know himself – so that, by knowing and loving God, men and women may also come to the fullness of truth about themselves” (Catholic Church & John Paul II, 1998, p. 1).

Do you believe this quote adequately depicts the Christian view of the interaction of faith and reason, and the value of both? Why or why not? Does the atheistic worldview also use faith and reason? Why or why not?

Reference: Catholic Church, & John Paul II. (1998).  Faith and reason: Encyclical letter Fides et ratio of the Supreme Pontiff John Paul II on the relationship between faith and reason. Vatican City: The Holy See. Retrieved from http://w2.vatican.va/content/john-paul-ii/en/encyclicals/documents/hf_jp-ii_enc_14091998_fides-et-ratio.html

Resurrection Salvation Faith & Reason

Why is the resurrection so important to the Christian worldview?,
How does one gain eternal life according to Christianity and how does this afterlife differ from other worldviews?,
How would you respond to concerns that Christianity’s claim of Jesus as the only way to salvation is exclusive?,
Does the quote from Pope John Paul II accurately reflect the Christian relationship between faith and reason?,
Does atheism also rely on faith and reason? Why or why not?

Two-Mirror Beam Scanning System

By Academic Wizard Blog

Two-Mirror Beam Scanning System

Here we consider system with two scanning mirrors to scan a laser beam in the focal plane of a microscope objective. We relay the scanners to the microscope pupil via a telescope consisting of a small first lens of focal length f1 = 75 mm and a larger lens of focal length f2 = 200 mm separated by the sum of their focal lengths. Ideally the second lens functions like a tube lens in that its back focal point is at the pupil of the objective and a real image is formed at the point where the rays cross in the figure.

Ideally, we would place the scanning mirrors at the front focal plane of the first lens so they would be conjugate to the microscope pupil. However, the two mirrors cannot occupy the same location so we place them 10 mm before and after this location. We will move the mirrors so that the laser beam moves through ±5 deg at the mirrors.

a. Where are the scanner images (as seen through the two relay lenses) relative to the pupil?

b. What is the angle of the scan after the two lenses (i.e. at these images).

c. As the beam is scanned, it moves away from the center of the pupil.

How far does it move? Draw pictures to show this.

d. If the focal length of the objective is 10 mm what is the full field of

view of the scanned image in millimeters?

Two-Mirror Beam Scanning System

Where are the scanner images located relative to the pupil after passing through the relay lenses?,
What is the scan angle after the two lenses at the image plane?,
How far does the beam move away from the pupil center as it scans?,
What is the full field of view (FOV) at the sample plane if the objective’s focal length is 10 mm?,
Can you provide diagrams to illustrate the beam movement and imaging?

Comprehensive General Answer:

Given Data:

First lens focal length, f₁ = 75 mm
Second lens focal length, f₂ = 200 mm
Distance between lenses = f₁ + f₂ = 275 mm
Scanner mirrors are placed at ±10 mm from the front focal plane of lens 1.
Scan angle at the mirrors: ±5 degrees
Objective focal length = 10 mm

Wellness Coaching Career Plan

What are four challenging situations you might face as a wellness coach?,
How would you handle these challenges?,
Which certification would you acquire to become a wellness coach?,
How would you develop a referral network?,
What resources and marketing strategies will sustain and grow your business?

Comprehensive General Answer:

Challenging Situations as a Wellness Coach & Solutions:

Client Resistance to Change – Clients may struggle with motivation or deny unhealthy habits. I would use motivational interviewing techniques, focusing on their values and small, achievable goals to foster gradual change.
Overstepping Professional Boundaries – Clients might seek therapy-level emotional support. I would establish clear coaching boundaries early and refer clients to mental health professionals when needed.
Inconsistent Client Commitment – Frequent cancellations or lack of follow-through are common. Setting up accountability structures, automated reminders, and re-aligning on their “why” would help improve consistency.
Competing in a Saturated Market – Standing out in a crowded wellness industry is tough. I would specialize in a niche (e.g., stress management for corporate employees) and build a strong personal brand through content and community engagement.

Pathway to Becoming a Wellness Coach:

Certification to Acquire:
I would pursue a certification from the National Board for Health & Wellness Coaching (NBHWC) or International Coach Federation (ICF). These are well-recognized and meet professional industry standards.
Developing a Referral Source:
Building relationships with local physicians, gyms, yoga studios, therapists, and nutritionists would be key. I would attend networking events, offer free workshops, and join local health organizations to establish credibility and create a strong referral pipeline.
Important Resources Needed:
- Practice management software (for scheduling, payments, client records)
- Professional liability insurance
- Business website with booking functionalities
- Continuing education materials (webinars, courses)
- Comfortable home office or rental space for client sessions
- Budget for marketing and initial branding
Marketing & Social Media Strategy:
I’d focus on building a strong online presence through:
- Content Marketing: Posting wellness tips, success stories, and video content on Instagram, LinkedIn, and YouTube.
- Email Newsletters: Regular value-packed emails to build trust and retain clients.
- Collaborations: Partnering with influencers, wellness bloggers, and local events.
- SEO Blogging: Writing articles addressing common health concerns to drive organic traffic.
- Targeted Ads: Running ads on Facebook and Instagram to reach my ideal client demographic.

Lunar Phases

By Academic Wizard Blog

Lunar Phases

1- Introduction

The lunar phase project involves observing the phase of the moon every day over a complete lunar cycle. For this project the observing location can change each day, but you must note it down in your observation section. Also, note that the time at which the moon will be visible will change during the cycle. Sometimes the moon will be visible during the day, and sometimes it will be visible at night. On occasion you may have to stay up late or wake up early in order to make an observation.

You should sketch an image of the phase of the moon in your log, and include the local sunrise and moonrise time that day. You can obtain the sunrise and moonrise time for any day by using the website. ( https://www.timeanddate.com/moon). You may choose your living zip code.

From the sunrise and moonrise time you can calculate the angular separation of the sun and the moon. Figure out how many hours and minutes pass between sunrise and the next moonrise. The earth rotates on its axis about 360 degrees in 24 hours, which means it rotates 15 degree every hour or 0.25 degrees every minute. You can convert the time separation between sunrise and moonrise into an approximate angular separation between the sun and the moon by multiplying each hour by 15 degree and each minute 0.25 degree. As an example, if the moon rises 3 hours and 12 minute after the sun, then the angular separation is 3*15+ 12*0.25 = 48 degree.

Lunar Phases

2- Observations.

Record your observations in the table below. Include the date and time you observed the moon, moonrise and sunrise times for the day, and a sketch of the phase of the moon as you see it that day.

Home Energy Usage Experiment

By Academic Wizard Blog

Home Energy Usage Experiment

Discussion- It’s possible to save a great deal of electrical energy (and money and natural resources) with some simple changes in household electrical use. The trouble is that most of these changes mean either changing behavior or spending money. Do an Internet search and review a few ways to save electrical energy. Discuss at least one change that you think would be reasonable and worthwhile to do in your own home in the next year. Provide your rationale.

Home Energy Use

In this activity, you are going to perform an experiment to track the amount of power you and your family use, then look at some basic patterns in that usage. (NOTE: If you live in an apartment or home in which you do not have access to the electrical meter, consult with your instructor about alternative arrangements, like teaming with a classmate to gather this data.)

This experiment is going to span the course of a full week and require 12 meter readings. It really involves two separate experiments:

tracking daily energy use for a week to compare any usage variations from day to day
comparing a single high-usage time period of a few hours with a single low-usage time period of a few hours to help you identify the extremes in your household electrical use

Home Energy Usage Experiment

You can easily do both experiments during the same time period. This approach would be the easiest and fastest way to proceed. Read the instructions for both Part A and Part B if you wish to do both experiments at the same time.

To begin, you’ll need to find your electric meter, which could be inside or outside of your home. Many electric meters these days are digital and pretty easy to read, but if you have an older “dial-type” meter, go to this electric meter reading guide to learn about how to read and understand it.

For each of the two experiments below, you will first record three simple pieces of data in a table:

1) day and date, 2) time, and 3) the kWh reading from the meter.

Then record the results of three simple calculations:

kWh used: Calculate kWh used since the last reading (subtraction).
Hours elapsed: Calculate the number of hours since the last reading (subtraction rounded to a whole number).
Average kW used: (kWh used)/(hours elapsed). If this number turns out to be 0.36, for example, it means that your average household power usage for the time period was about 360 watts, the equivalent of running six 60-watt bulbs for that whole time period.

Part A

Daily Electrical Usage: Data Collection

Pick a convenient time of day to take readings from your electric meter. You’ll need readings roughly a day apart, but if they differ by only an hour or two, that should be fine. Pick a consistent time you’ll remember, though, such as after getting home for the day. You need to start by doing an initial meter reading, then follow up with a reading every day for the next 7 days. You’ll do 8 readings in all.

Record your readings in the tables below. In addition to the data fields described above, there is a lot of room for usage notes. Record anything that might have substantially affected the electrical usage since your previous reading. This might include the amount of time people were around and awake at home, use of specific devices such as an air conditioner, clothes dryer, TV, or lighting.

Home Energy Usage Experiment

Usage Extremes: Data Collection

For this experiment, you’ll measure electrical usage during a time period when you expect to have very light electrical usage (for instance, while you’re asleep at night or during the day when no one is at home). Likewise you’ll measure electrical usage during a time period when you expect to have heavier than average electrical usage. This time period might be in the evening, when lights and other appliances are on. Both of these time periods should be at least 4 hours long, to increase the accuracy of your results.

Record your results in the tables below for each situation. For each time period, you’ll need to take an initial and a final reading.

Part C

Let’s start the analysis by looking at your “extreme usage” cases. Compare the two cases in detail—low usage period versus high usage period. Discuss differences between the two as well as any surprises. Things you should cover in your discussion: How much difference was there in average power usage (avg. kW) between the low-usage and high-usage time periods? What might have been running during the low-usage period that used energy? Identify likely “stealth” energy users that you could not turn off during the low-usage period. What do you suppose contributed most to the usage during the high-usage period?

Part D

Having looked at your “extreme usage” cases, analyze your day-to-day usage. Discuss in detail. Specifically, compare higher usage days to lower usage days. Were there significant variations? Do your conclusions regarding the “extreme” cases help to explain any daily variations? What were the surprises or new insights you had in reviewing this day-to-day usage record?

Part E

It is possible to save a great deal of electrical energy (and money and natural resources) with some simple changes. You’re probably familiar with what some of those changes are and are now more attuned to your own electrical usage. The trouble is, most of these changes either mean changing behavior or spending money. Search the Web for a few ways to save electrical energy. Record them below and categorize them, if possible, as “change behavior” or “spend money.” You might want to consider adding a “neither” category. There are a few things that don’t really require much change or money at all. Include your sources in your answer.

What Is “Wasted” Electrical Energy?

Discuss the production, transmission, and usage of electricity in the context of conservation of energy. When electricity is “used” or we say that energy is “wasted,” what is actually happening?

Electrical Safety Devices

Perform an Internet search to learn about grounding wires, fuses, and circuit breakers. Specifically,

describe how each device works; and
relate its function to what you’ve learned in this unit about electric current, voltage and resistance.

What is one reasonable and worthwhile change you can make at home to save electrical energy?,
How do you track daily household energy use for a week?,
How does your home’s energy usage vary between high-usage and low-usage periods?,
What are some behavioral or monetary changes to reduce electrical energy consumption?,
What happens when electrical energy is “wasted” during production transmission or usage?
