 explain why ethical hacking is necessary in today’s complex business environment. 

 First one

In  recent years, many firms use algorithms to help make management group’s  decisions and optimize operation processes and supply chains. When such  algorithms produce unexpected outcomes, bias concerns may arise. Thus,  removing these kinds of bias from the data is so critical in data-driven  business. Based on this case anlaysis, please elaborate on the  questions below.

Q1) Please address the concept of ‘algorithmic bias’ in a marketing context. What is the reason behind the bias in this case?

Q2)  How might a firm acquire capability to analyze situations and detect  whether algorithmic bias occurs and how it can be mitigated?

Q3)  Algorithmic bias can occur even when demographic data is not used as a  variable by the algorithm. What would you play a role as an information  sysem manager if a bias was brough to your attention?

Second One:

The  role of the database and data administrator have evolved over  time. They continue to evolve in light of new technologies such as  blockchain, IoT, and security-based solutions. What do you believe the  future job description will look like for a database engineer in 5-10  years from now? 

Please create your OWN job description. Do not copy that of others.

 2.1 Scholarly Abstract Assignment – Quantitative

Create a 1-2 page single-spaced Analysis of Research abstract published scholarly articles related to a topic you selected in Week 1. This article should reflect a quantitative research method.

Brevity and being concise are important as this analysis is intended to be a brief summation of the research.

Each abstract must therefore consist of the following in this order:

1. Bibliographic Citation – use the correctly formatted APA style citation for the work as the title of your abstract, displaying the full citation in bold font.

2. Author Qualifications – name the qualification of each author conducting the research

3. Research Concern – one paragraph summary of the reason for the overall research topic

4. Research Purpose Statement AND Research Questions or Hypotheses – specific focus of the research

5. Precedent Literature – key literature used in proposing the needed research (not the full bibliography or reference list)

6. Research Methodology – description of the population, sample, and data gathering techniques used in the research

7. Instrumentation – description of the tools used to gather data (surveys, tests,interviews, etc.)

8. Findings – summation of what the research discovered and the types of analysis that were used to describe the findings (tables, figures, and statistical measures)

9. Conclusions – what did the findings show and how does that relate to current research

10. Suggestions for further research – based on the conclusions of the study, what additional research is needed.

Secure Network Application Project Assignment Instructions

Using Microsoft Visio or a subsequent visual design tool, diagram a network in which you are familiar. 

Write a thorough report detailing the design.

The report must be a minimum of 5 pages excluding the title page, Visio diagram(s), and references.

It must include, at a minimum, 10 peer-reviewed sources to justify the design. 

In the design include (at a minimum):

· 4 Application servers

· 2 Virtual environments

· 4 File servers

· 2 Database servers

· 2 Storage Area Networks

· 4 Virtual Local Area Network segmentations for different roles/levels of user permissions

· 2 Virtual Private Networks

· Appropriate network switches and routers to host the client server architecture

· 2 Demilitarized Zones

· 4 Firewalls

Total 10 Pages 10 references

  The Database System Life Cycle, otherwise known as the System Development Life Cycle (SDLC), consists of five important steps:

1. Investigation.

2. System Design.

3. Development.

4. Execution.

5. Maintenance.

Research the Database System Life Cycle. Find at least two references to it. Note that the names and wording in the steps of the life cycle may superficially vary between different sources. Focus on understanding the concepts presented, rather than the language.

· Summarize each step and describe how they work together.

· Explain how you have used, or can use, the cycle in another context. For example, how can these steps be used when buying a car or planning a trip?

· Use a table to show parallels between developing a database and performing the task you chose.

1) Is the topic clearly related to education?

(2). Is your introductory paragraph interesting and relevant? (How can this be made even better?)

(3). Is there a clear thesis at the end of the intro paragraph? (Is it argumentative or just factual? How can it be improved?)

(4). Is there a clear focus in the topic sentence of the main body paragraph? (If so, how can it be improved further? If not, what do you suggest the focus should be?)

(5). Does each paragraph support the focus of the topic sentence (paragraph unity)? (Explain how this can be improved throughout the paper)

(6). Is solid evidence used to support the thesis? (minimum of 5 sources listed in the Works Cited, which means 5 in-text references in the body of the paper. Are there areas where the paper could use more evidentiary support?)

(7). Is MLA formatting followed? (What are the mistakes, and how can they be fixed?)

(8). Are grammar and mechanics mistakes minimal? (What are the mistakes, and how can they be fixed?)

 Hello, Please find the discussion related questions. It should be more than 450 words with combined 6 questions. Need to submit this by 8 PM EST today.

Questions Starts from here :-

Let’s assume that you have an existing relational database.

• What options do you have for removing a table from the database?
• Is it possible to modify a table, i.e., adding or removing a column or changing a column’s type? 
• Can you remove any table at any time?
• What happens to foreign key references when a table is dropped?
• Are there restrictions on dropping tables?
• Can you modify any table in any way or are there limits?

Do some research on this focusing on SQLite as the database. What are the SQL statements for such activities? Provide examples.

Post your findings by the due date and respond to at least one other person in your assigned group within 48 hours after the due date. Contrast what they have found with what you have.

Note that we will grade your first post only and your reply. Do not make “dummy posts”. Of course, if you consult or use any external sources, cite them and do not directly copy from sources.

No posts or replies are accepted after 48 hours after the due date.

Constraints, Design, and Implementation
Discuss the importance of integrity constraints (e.g. entity integrity, referential, and domain) to the success of database design and implementation.

Discussion Guidelines
You must provide an original response of 300+ words of your own 

Textbook

 Printed Textbook: Database Systems: Design, Implementation, and Management, 13th
edition, Coronel and Morris.  

I am taking the following online course, Pearson Education MyLab IT.  The course has 13 tutorials and tests.  Is this something you can do this week, and if so, what is the cost?

Thanks
