Answer the following the question:

We live in a world of data, perhaps too much data. Organizations continue to store data indefinitely. In fact, about 90% of the data stored on todays databases is deemed worthless within 3 months. Think about your email. How often do you ever go back to an email from six months ago. But you still keep it for what? How should organizations government personal data in a data warehouse? What are some best practices you might suggest to your organization if you were the CIO to ensure that the data in the system was maintained properly?

Instructions

• This is a required assignment, worth 15 points. The assignment must be submitted by the due date. Late assignment are not allowed. 
• You are required to submit a minimum of two postings. Points will be deducted for not fulfilling this minimum requirement.
• Apply and use the basic citation styles of APA is required. Points are deducted per the rubric for this behavior.
• Do not claim credit for the words, ideas, and concepts of others. Use in-text citation and list the reference of your supporting source following APA’s style and formatting. Points are deducted per the rubric for this behavior.
• Do not copy and paste information or concepts from the Internet and claim that is your work. It will be considered Plagiarism and you will receive zero for your work. A second offense results in a zero for the course. A third is termination from the university.

 A postfix expression is an expression in which each operator follows its operands. Table 13.4 shows several examples of postfix expressions. The grouping marks under each expression should help you visualize the operands for each operator. The more familiar infix expression corresponding to each postfix expression is also shown. The advantage of the postfix form is that there is no need to group subexpressions in parentheses or to consider operator precedence. The grouping marks in Table 13.4 are only for our convenience and are not required. You may have used pocket calculators that require the entry of expressions in postfix form. Use an adaptation of your stack library from Project 3 to write a program that simulates the operation of a calculator by scanning an integer expression in postfix form and displaying its result. Your program should push each integer operand onto the stack. When an operator is encountered, the top two operands are popped, the operation is performed on its operands, and the result is pushed back onto the stack. The final result should be the only value remaining on the stack when the end of the expression is reached. 

You will review both quantitative and qualitative research.  The topic is up to you as long as you choose a peer-reviewed, academic research piece.  I suggest choosing a topic that is at least in the same family as your expected dissertation topic so that you can start viewing what is out there.  There are no hard word counts or page requirements as long as you cover the basic guidelines.  You must submit original work, however,  and a paper that returns as a large percentage of copy/paste to other sources will not be accepted.  (Safe Assign will be used to track/monitor your submission for plagiarism. Submissions with a Safe Assign match of more than 25% will not be accepted.) 

Please use APA formatting and include the following information:

• Introduction/Background:  Provide context for the research article.  What led the author(s) to write the piece? What key concepts were explored? Were there weaknesses in prior research that led the author to the current hypothesis or research question?
• Methodology:  Describe how the data was gathered and analyzed.  What research questions or hypotheses were the researcher trying to explore? What statistical analysis was used?
• Study Findings and Results:  What were the major findings from the study? Were there any limitations?
• Conclusions:  Evaluate the article in terms of significance, research methods, readability and the implications of the results.  Does the piece lead into further study? Are there different methods you would have chosen based on what you read? What are the strengths and weaknesses of the article in terms of statistical analysis and application? (This is where a large part of the rubric is covered.) 
• References   

Initial Post

There are countless graphs and charts to choose from when converting raw data into a visual format. For many, it can be difficult to decide whether to rely on a straightforward pie chart or bar graph or to opt for a more spatially complex chart type.

Two common questions we often hear are: “How do you know which graph to use?” and “How do you know which chart to use?” The answer, as always, depends on the nuances of your readership, including their experience level and familiarity with big data analytics.

Based upon your understanding of data visualizations, what are 5 Data Visualization pitfalls? What would you do to fix these pitfalls? How can you avoid making future mistakes in your own visualizations?

For the final project, you will be conducting a forensics investigation using one of the following items:

1. A smartphone
2. A network (ideally, a wireless network)

 You may use either for your investigation. However, be aware of legal issues surrounding your data gathering. If you are using any system you do not personally control and have authority to investigate/discover, please get written permission from the owner/operator of the system or refrain from your forensics analysis of that systems and use a personal system. For a network, you can use your own personal home network. For a smartphone, consider using an image from the Internet or a personal device. There could be issues related to using a live, active, personal device (example: corruption of the device). If using a personal device, consider using an old, outdated phone, if available.

 You will review various forensics tools used with your selected system. Select a tool and use that tool to gather forensics data for analysis. You are simulating the process of gathering this data, so you do not need to investigate a compromised device or system. The project deliverables are as follows:

 Week 7 – Prepare an investigative report of the forensics data capture conducted using the tool selected for this purpose. The paper should provide the following information: 

• Executive Summary of your investigation, including a description of the device or systems and the tool used for the forensics analysis
• Step-by-step description you used to gather data for analysis
• Report on the information that was obtainable from the device
• Graphics evidence that you conducted the forensics data gathering and analysis

 The paper should be in a form that would be used for reporting to a court or a law enforcement agency. Be sure to provide graphics evidence of your forensics investigation effort (Screenshots, reports, etc.). References should be in APA format.

The Hamilton Civic Center is developing a template for member exercise and off-site seminars. You create the template, set validation, enter formulas, and insert a combo box control. You then create a new workbook from the template.
