Final Project (Option 2: Case Study focusing on
Cybercrime Investigation)
This
assignment does not require conducting any digital forensic analysis via EnCase.
However, you need to reflect all the class lectures that you have learned
throughout this course. Consider this assignment is creating a training manual
for presenting the evidence to the court as an expert-testimony.
Ross Ulbricht’s Silk Road had about a million
registered users from all over the world with many illegal items and services
available to the users. Interestingly, the Digital Citizens Alliance reported
that the number of drug listings actually increased on Silk Road after
Ulbricht’s arrest in October 2013.
Silk Road, an illicit online market functioning within
the “Deep Web” would be a good example of a contemporary drug market operation.
According to the F.B.I., Silk Road is the most sophisticated and extensive
criminal market place on the Internet today. 
Silk Road is similar to Amazon or Ebay, but it is used
for illicit merchandise. The marketplace made the sale of everything from
narcotics to weaponry possible: similar to purchasing a book on Amazon. Bitcoin
was designed to eliminate the need for trust through mathematical proof of
work. Trust and the ability to ensure the security and reliability of
transactions are crucial to sustained iterative commerce. The ability to ensure
trust in a digital currency was a major turning point that has largely facilitated
the success of Bitcoin. Although Bitcoin was not designed with anonymity in
mind, its construction provides anonymity to its users as evidenced in the 2013
indictment of Silk Road founder Ross Ulbricht (Brantly, 2014).
The Final Project will reflect your class activities
and need to demonstrate class themes and topics.

It’s easy to get smarter about your money when you have a head start. 
In this assignment, you will use Excel to create a household budget to help maintain control over your finances and see how your money is being used.
Conduct a short internet job search for the type of position you will be applying for once you have completed your education. Consider your work experience in this search. For example, if you have no experience in field, please search for entry level positions or the type of position someone with your background could reasonably qualify for. Look for three positions that include wage/salary information. Once you have found 3 job ads that include salary information, determine the average starting salary and use this as the basis for your household budget.
Create an Excel spreadsheet of your own design to breakdown your household budget. List monthly expenses and monthly income. You will need to list your expenses for 12 months (so you should have columns for each month, use Excel shortcuts).  Remember your expenses are not always the same every month (for instance your electric bill could fluctuate based on how hot it is). Be sure to format the expenses and income as currency using one of the formatting options in Excel. Do NOT use an online template. The designs must be easy and logical to read.  You should start from a blank, clean, Excel document.
Requirements of the assignment
Title your spreadsheet with a meaningful title, in bold, at least 16 point size, centered above your spreadsheet content and is centered over more than 3 columns. Use “Merge & Center” provided in Excel. The rest of the document should be in 12 point font.  All data that represents money is formatted as currency.
Write your job title and the city and state you will live in.
Include 3 job titles, locations, and starting salaries from the job search you performed.  Find the average starting salary (using the AVERAGE function) Calculate and label your monthly income by dividing the annual income cell (reference the cell) by 12. Please make sure that your salary realistically and accurately matches your skill set (for instance, you will not start an engineering job making 90,000 a year).
Include at least 8 expense items such as electricity, telephone, gas, groceries, rent/mortgage, car payment, student loan payments, credit card payments, entertainment allowance, clothing allowance, etc.
Make all negative numbers appear in red using automatic formatting or conditional formatting provided in Excel. Choosing RED as the choice for the font color is not correct. Apply this formatting to the entire worksheet.  You must have a negative somewhere in your calculations
For the following items, you MUST use an Excel function. You cannot calculate the values and enter a number. Excel functions include SUM, AVERAGE, MIN, MAX, etc. You must choose the correct Excel function and then use it properly to get full credit.
Using an Excel function, calculate the average of each type of expense category for the months you have listed. You must select the right function, such as SUM or AVERAGE, and then use the function correctly in the cell you have selected. Be sure to label the row or column (note this will depend on how you set up your budget sheet).
Calculate a subtotal for each expense category, using a function provided in Excel. You must select the right function, such as SUM or AVERAGE, and then use the function correctly in the cell you have selected. Be sure to label the row or column (note this will depend on how you set up your budget sheet).
Calculate a subtotal for each month, then a grand total of all the months, using functions provided in Excel. You must select the right function, such as SUM or AVERAGE, and then use the function correctly in the cell you have selected. Be sure to label the row or column (note this will depend on how you set up your budget sheet).
Calculate your monthly income after expenses. For each month, subtract the monthly expenses from the monthly income. You must select the right function, such as SUM or AVERAGE, and then use the function correctly in the cell you have selected. Be sure to label the row or column (note this will depend on how you set up your budget sheet).
Include a pie chart to display the breakdown of expenses. Use the expense categories you have listed and the monthly totals you have calculated to create your pie chart.  Put the pie chart on its own worksheet labeled “Chart”.  Please note, the chart values should be from the budget page of the worksheet.  Do not copy the values into the new worksheet.
Make sure your spreadsheet is clearly organized and well formatted. For example, no values should display as ##### so make sure your columns are of the correct width for the data.
Check your spelling
Create a footer displaying the filename.
Save your completed file with the filename formatted as Excel_Budget_yourfirstname_yourlastname.xls. An Excel document should be uploaded to D2L.

In this assignment, we are developing an online e-commerce website (similar to eBay). You are implementing a version of AuctionBase (which is based on an assignment from the University of Wisconsin).
User registers to the website (using a username, email, name, address, and phone number. ) Each user is identified by a unique id.
A user can be a buyer or a seller (or both).
Auction runs only on a single item.
A seller places items for Auction.
The item is identified by an ID and has a name and may belong to multiple categories, a location (which may be different from the seller location), and descriptions.
For each category, we keep track of its id, name, and description.
Auctions would have a start time, end time, and a starting asking price.
A buyer can bid on items, the bid with the highest bid win the auction.
A buyer may review the seller (a rating from 1 to 5) and write feedback.
The seller specifies the shipping options that may include pickup, each shipping option has a price and time.
The seller provides her bank information (bank name, routing number, and account no).
The system stores the payment information for credit card information (card number, expiration date, CCV code, name, and billing address).
The winner bidder specifies her choice of shipping method and has to pay for the price of bid and shipping cost.
The status of the buyer payment is recorded, upon the successful payment, the seller must ship the order within two business days.
The tracking information (of shipment) is recorded, if applicable. The buyer confirms the delivery of the item. The payment is released to the seller after delivery is confirmed.
Each bid must be higher than the previous one.
For each auction, we store the number of bids and the last price (this information is stored for performance).
To simulate the execution of the system, we create a table for the current time.
This table should at all times contain a single row (i.e., a single value) representing the current time of your AuctionBase system.
Constraints for Users
No two users can share the same User ID.
All sellers and bidders must already exist as users.
The bidder must have a valid credit card.
Constraints for Items
No two items can share the same Item ID.
Every bid must correspond to an actual item.
An item cannot belong to a particular category more than once.
The end time for an auction must always be after its start time.
The Current Price of an item must always match the Amount of the most recent bid for that item.
Constraints for Bidding
A user may not bid on an item he or she is also selling.
No auction may have two bids at the exact same time.
No auction may have a bid before its start time or after its end time.
No user can make a bid of the same amount to the same item more than once.
In every auction, the Number of Bids attribute corresponds to the actual number of bids for that particular item.
Any new bid for a particular item must have a higher amount than any of the previous bids for that particular item.
Constraints for Time
All new bids must be placed at the time which matches the current time of your AuctionBase system.
The current time of your AuctionBase system can only advance forward in time, not backward in time.
Deliverable
Design EERD schema for the system.
Create the Relation model in SQL
Design your constraints: Create a file called constraints.txt in this file, you will specify, in plain English, how you implemented each of the 16 constraints in your database schema, if possible.
Implement your constraints. (Trigger or otherwise). (bonus)
Import EBay data into your database (bonus)
