This answer was rated:

You have been asked to design a database system for DonationDollars, a company that wants to facilitate donations to non-profit organizations via an online service. To do this, DonationDollars presents an online profile for each company on a website. Here, other people can make donations to the cause. The website shows the number of dollars gathered in a given time, the people who donated (can be by name or anonymous) and the amount of money donated.

In addition to facilitating this exchange online, DonationDollars needs to transfer all money to the correct organization, send a thank-you letter to the person who is donating the money (for tax deduction purposes) and keep track of the total amounts of dollars donated to all different companies.

For example, one organization that uses DonationDollars could be the Pet Orphanage, a shelter for animals. As an individual, you can donate money online to the Pet Orphanage using the website put up by DonationDollars.

Design a database for this project.

1. Show the ER diagram for your database. There should be at least 4 entities with their relations. Clearly describe and explain all the symbols you use for your ER diagram.

2. Describe at least one stored procedure for this project in detail. Explain why using a stored procedure would be a good idea. Explain what the stored procedure would do using pseudo-code.

3. Explain the difference between an ER diagram and your final database diagram showing the tables.

4. As a software designer, you suspect that DonationDollars will want to do data mining later on to better focus on specific donors. What type of Big Data from social networks would you recommend they look at? How would it be used concurrently with your database?
