The IT Director at the Regional Economic Studies Institute (RESI), an economic and policy analysis/research group at Towson University, learned that you are taking a database management system class this fall, and she decided to hire you as a DBA. They would like to design an ER schema for keeping track of information about votes taken in the U.S. House of Representatives during the current two-year congressional session. The database needs to keep track of each U.S. STATE’s Name (e.g., ‘Texas’, ‘New York’, ‘California’) and include the Region of the state (whose domain is {‘Northeast’, ‘Midwest’, ‘Southeast’, ‘Southwest’, ‘West’}). Each CONGRESS_PERSON in the House of Representatives is described by his or her Name, plus the District represented, the Start_date when the congressperson was first elected, and the political Party to which he or she belongs (whose domain is {‘Republican’, ‘Democrat’, ‘Independent’, ‘Other’}). The database keeps track of each BILL (i.e., proposed law), including the Bill_name, the Date_of_vote on the bill, whether the bill Passed_or_failed (whose domain is {‘Yes’, ‘No’}), and the Sponsor (the congressperson(s) who sponsored—that is, proposed—the bill). The database also keeps track of how each congressperson voted on each bill (domain of Vote attribute is {‘Yes’, ‘No’, ‘Abstain’, ‘Absent’}). Your first task is on the job is to draw an ER diagram for this application. State clearly any assumptions you make.

You are volunteering for a local children's softball league. They asked you to create an app or a Web application to help in their operations. You decide to create a database. The league consists of several teams. Players are assigned to teams at the start of the season. It also collects parents' contact information, and charges season and optional equipment rental fees. League volunteers include officials, referees, coaches, and first aid attendants. Parents also volunteer to help at individual practices and games. The teams meet for regular practices at several ballparks at public parts; practices are scheduled, and permits are obtained from the city. Regular season and playoff games are scheduled at some or all of these ballparks; results and player statistics are collected.

For the first draft of your system:

1) Identify business rules your design will capture.

2) Identify entities, keys, and constraints. Create an ER diagram (format and software package up to you). You can also design your database directly in terms of DB tables. (one possible tool: https://sqldbm.com/Home/ ).

3) Based on ER model, design a database (skip this step if your design is already in DB-specific terms). Suggest foreign key constraints and indexes.

4) Is your design in 3rd Normal Form. If so, explain. If it is not, revise your design until it is in 3NF.

5) Generate or write SQL DDL statements that create your database objects.

Gen. Robert E. Lee's Boyhood Home is for Sale

The historic Virginia home that Confederate Gen. Robert E. Lee grew up in hit the market (in April 2018) for $8.5 million. (Trapasso, C.)

Robert E. Lee's father Henry rented the home in 1812, according to The Washington Post. The family lived there for over 80 years, including Robert E. Lee from age five to when he went to West Point in 1825. He again visited five years after the Civil War ended, The Post reported. (Leayman, E.)

The home's other claim to fame is that President George Washington also dined and lodged there before the Lee family moved in. (Trapasso, C.)

Built in 1795, the brick house was listed on the National Register of Historic Places in 1986. (Trapasso, C.)

The home had been used as a residence until 1966. The Stonewall Jackson Memorial Foundation purchased the home and opened it to the public. Unable to make ends meet, the foundation sold the home in 2000 to Mark and Ann Kington for $2.5 million. (Trapasso, C.)

The boyhood home of Robert E. Lee in Alexandria was listed on the market with a significant price drop. Previously priced at $8.5 million, the six bedroom is available for $6.2 million (March 2019). (Leayman, E.)

1. Calculate the annual compound growth rate of the house price since the house was sold to Mark and Ann Kington (since 2000) until the house was listed for sale at a reduced price in 2019. (Round the number of years to the whole number). Please show your work.
2. Assume that the growth rate you calculated in question #1 remains the same for the next 30 years. Calculate the price of the house in 30 years after it was listed at a reduced price in 2019. Please show your work.
3. Assume that the growth rate you calculated in question #1 remains the same since Robert E. Lee's father Henry rented the home in 1812. Calculate the price of the house in 1812. (Round the number of years to the whole number). Please show your work.
4. Assume the growth rate that you calculated in #1 prevailed since 1795. Calculate the price of the house in 1795. (TIP: To get the answer correctly you need to use the price of the house in your calculations in dollars with all zeros). Please show your work.
5. You were using the time value of money concept to answer question #4. Think about the time line for that problem. What is the time point 0 in that problem? Please explain your answer.
6. In April 2018, the listed price of the house was $8.5 million. Calculate the annual compound growth rate of the house price since the house was sold to Mark and Ann Kington (since 2000) until the house was listed for sale in 2018. Compare with your answer to the question #1.
7. Using the growth rate from question #6, calculate the price of the house in 1812. (Round the number of years to the whole number). Please show your work. Compare with your answer to the question #3.
