DAD 220 Database Documentation Template Complete these steps as you work through the directions for Project One. Replace the bracketed text with your screenshots and brief explanations of the work they capture. Each screenshot and its explanation should be sized to approximately one quarter of the page, with the description written below the screenshot. Follow these rules for each of the prompts and questions below. Review the example document located in the Project One Supporting Materials for assistance. Step One: Create a Database 1. Navigate to your online integrated development environment (IDE). List and record the SQL commands that you used to complete this step here:

Explanation: chmod +x change_perm.sh ./change_perm.sh Mysql use muttitt;. 2. Create a database schema called QuantigrationUpdates. List out the database name. Provide the SQL commands you ran against MySQL to successfully complete this in your answer:

Explanation: CREATE DATABASE QuantigrationUpdates; 3. Using the entity relationship diagram (ERD) as a reference, create the following tables with the appropriate attributes and keys: a. A table named Customers in the QuantigrationUpdates database, as defined on the project ERD. Provide the SQL commands you ran against MySQL to complete this successfully in your answer: Explanation: CREATE TABLE Customers (CustomerID INT, FirstName VARCHAR(25), LastName VARCHAR(25), StreetAddress VARCHAR(50), City VARCHAR(50), State VARCHAR(25), ZipCode VARCHAR(10), Telephone VARCHAR(15), PRIMARY KEY(CustomerID)); b. A table named Orders in the QuantigrationUpdates database, as defined on the project ERD. Provide the SQL commands you ran against MySQL to complete this successfully in your answer:

Explanation: CREATE TABLE Orders (OrderID INT NOT NULL PRIMARY KEY, CustomerID INT, SKU VARCHAR(20), Description VARCHAR(50), FOREIGN KEY (CustomerID) REFERENCES Customers(CustomerID)); c. A table named RMA in the QuantigrationUpdates database, as defined on the project ERD. Provide the SQL commands you ran against MySQL to complete this successfully in your answer: Explanation: CREATE TABLE RMA (RMAID INT NOT NULL PRIMARY KEY, OrderID INT, Step VARCHAR(50), Status VARCHAR(15), Reason VARCHAR(15), FOREIGN KEY (OrderID) REFERENCES Orders(OrderID)); Step Two: Load and Query the Data 1. Import the data from each file into tables.  Use the QuantigrationUpdates database, the three tables you created, and the three CSV files preloaded into Codio.

 Use the import utility of your database program to load the data from each file into the table of the same name. You will perform this step three times, once for each table. Explanation: Customers: LOAD DATA INFILE '/home/codio/workspace/customers.csv' INTO TABLE Customers FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n'; Orders: LOAD DATA INFILE '/home/codio/workspace/orders.csv' INTO TABLE Orders FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n'; RMA: LOAD DATA INFILE '/home/codio/workspace/rma.csv' INTO TABLE RMA FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n'; 2. Write basic queries against imported tables to organize and analyze targeted data. For each query, replace the bracketed text with a screenshot of the query and its output. You should also include a 1- to 3-sentence description of the output.  Write an SQL query that returns the count of orders for customers located only in the city of Framingham, Massachusetts. i. How many records were returned? 505

Explanation: There were 505 records returned. The query used counted the number of orders placed by customers in Framingham, MA. INNER JOIN combines the customers and orders. WHERE specified the city and state. SELECT COUNT(*) FROM Customers INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID WHERE UPPER(Customers.city) = 'FRAMINGHAM' AND UPPER(Customers.state) = 'MASSACHUSETTS';  Write an SQL query to select all of the Customers located in the state of Massachusetts. i. Use a WHERE clause to limit the number of records in the Customers table to only those who are located in Massachusetts. ii. Record an answer to the following question: How many records were returned? 982 Explanation: There were 982 records returned for the customer orders in Massachusetts. SELECT COUNT(*) FROM Customers WHERE UPPER(Customers.state) = 'MASSACHUSETTS';  Write a SQL query to insert four new records into the Orders and Customers tables using the following data: Customers Table
