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:

Image 1: Image 1 displays the required commands needed to navigate to the online IDE. Commands: ->mysql; 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: Image 2: Image 2 shows the sql commands used to create the QuantigrationUpdates database. commands: mysql> create database QuantigrationUpdates; mysql> show databases;

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: Image 3: Image 3 shows the creation of table Customers inside the QuantigrationUpdates database. commands used: mysql> use QuantigrationUpdates; mysql> CREATE TABLE Customers( -> CustomerID int primary key,

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. Image 6: Image 6 displays the sql codes utilized to load csv information into tables in the QuantigrationUpdate database. Commands used to load data into customers table: mysql> LOAD DATA INFILE '/home/codio/workspace/customers.csv' -> INTO TABLE Customers -> FIELDS TERMINATED BY','

-> ENCLOSED BY "" -> LINES TERMINATED BY '\r\n'; Commands used to load data into Orders table: mysql> LOAD DATA INFILE '/home/codio/workspace/orders.csv' -> INTO TABLE Orders -> FIELDS TERMINATED BY',' -> ENCLOSED BY "" -> LINES TERMINATED BY '\r\n'; Commands used to load data into RMA table: mysql> LOAD DATA INFILE '/home/codio/workspace/rma.csv' -> INTO TABLE RMA -> FIELDS TERMINATED BY ',' -> ENCLOSED 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?

Image 7: Image 7 shows the query run to determine the total number of customers who reside in Framingham, Massachusetts. From the query, it can be determined that there are 505 customers who reside in only Framingham, Massachusetts. Commands used: mysql> Select Count(*) AS OrderCount -> From Customers c JOIN Orders o ON c.CustomerID=o.CustomerID WHERE c.City = 'Framingham' AND c.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? Image 8: image 8 shows the results of the queries run to determine the number of customers who reside in Massachusetts. From the query, it is determined that 982 customers reside in Massachusetts. Commands used: mysql>SELECT * From Customers Where State = ‘Massachusetts’; ● Write a SQL query to insert four new records into the Orders and Customers tables using the following data:

Customers Table CustomerI D FirstName LastNam e StreetAddress City State ZipCod e Telephone 100004 Luke Skywalker 15 Maiden Lane New York NY 10222 212-555-1234 100005 Winston Smith 123 Sycamore Street Greensbor o NC 27401 919-555-6623 100006 MaryAnne Jenkins 1 Coconut Way Jupiter FL 33458 321-555-8907 100007 Janet Williams 55 Redondo Beach Blvd Torrence CA 90501 310-555-5678

Image 9: Image 9 displays the SQL commands used to insert 4 rows into the Customers table in the QuantigrationUpdates database. Commands used: mysql> INSERT INTO Customers VALUES -> (100004,'Luke','Skywalker','15 Maiden Lane','New York','NY','10222','212-555-1234'), -> (100005,'Winston','Smith','123 Sycamore Street','Greensboro','NC','27401','919-555-6623'), -> (100006,'MaryAnne','Jenkins','1 Coconut Way','Jupiter','FL','33458','321-555-8907'), -> (100007,'Janet','Williams','55 Redondo Beach Blvd','Torrence','CA','90501','310-555- 5678'); Orders Table OrderID CustomerID SKU Description 1204305 100004 ADV-24-10C Advanced Switch 10GigE Copper 24 port 1204306 100005 ADV-48-10F Advanced Switch 10 GigE Copper/Fiber 44 port copper 4 port fiber 1204307 100006 ENT-24-10F Enterprise Switch 10GigE SFP+ 24 Port 1204308 100007 ENT-48-10F Enterprise Switch 10GigE SFP+ 48 port

Image 10: Image 10 shows the SQL commands used to insert four new rows into the Orders table of the QuantigrationUpdate database. Commands used: mysql> INSERT INTO Orders Values -> (1204305, 100004,'ADV-24-10C','Advanced Switch 10GigE Copper 24 port'), -> (1204306,100005,'ADV-48-10F','Advanced Switch 10 GigE Copper/Fiber 44 port copper 4 port fiber'), -> (1204307,100006,'ENT-24-10F','Enterprise Switch 10GigE SFP+ 24 Port'), -> (1204308,100007,'ENT-48-10F','Enterprise Switch 10GigE SFP+ 48 port'); ● In the Customers table, perform a query to count all records where the city is Woonsocket, Rhode Island.

i. How many records are in the Customers table where the field “city” equals “Woonsocket”? Image 11: Image 11 shows the SQL commands used to find the total number of customers who live in a city called Woonsocket. From the results of the queries, it can be determined that 7 customers reside in cities called Woonsocket. commands used: mysql> Select Count(*) as RecordCount -> From Customers -> Where City='Woonsocket'; ● In the RMA database, update a customer’s records.

i. Write an SQL statement to select the current fields of status and step for the record in the RMA table with an orderid value of “5175.” 1. What are the current status and step? Image 12: Image 12 demonstrates the sql commands used to determine the step and status of OrderID 5175. From the query, it is determined that Order 5175 has a step value of “Awaiting customer Documentation’ and a status value of ‘Pending’. Commands used: mysql> Select Status, Step -> FROM RMA -> Where OrderID=5175; ii.
