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: [ 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: CREATE DATABASE QuantigrationUpdates; SHOW DATABASES;

CREATE DATABASE QuantigrationUpdates; command created a new database command with the name “QuantigrationUpdates”. The “create database” command was used to initiate the creation of a new database in a database management system. After this command the system attempted to create and successfully did create a new database that was empty with the listed name QuantigrationUpdates SHOW DATABASES; command is a standard command used in MySQL which shows the full lists of all the existing databases in the current server. When I used this command in this case the system did as it does and showed the current databases including the new one I created QuantigrationUpdates, proving it to be successful 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: CREATE TABLE Customers (CustomerID INT, FirstName VARCHAR(25), LastName VARCHAR(25), StreetAddress VARCHAR(50), City VARCHAR(50), State VARCHAR(25), ZipCode VARCHAR(15), Telephone VARCHAR(15), PRIMARY KEY(CustomerID));

Describe Customers; The first command created the new table “Customers” in the database, the table contains many columns each having its own data included. The PRIMARY KEY(CustomerID) is a statement that designated the “CustomerID” column as the primary key for this table at the end. This ensures that each of the entries in the column is unique and is a point of reference to correctly identify each customer record in its own unique way. The second command gives the description of the new customers table that was created and the data that is currently in the table. In executing this command it shows that all of the data so far has been correctly loaded into the table. 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: CREATE TABLE Orders (OrderID INT NOT NULL PRIMARY KEY, CustomerID INT, SKU VARCHAR(20), Description VARCHAR(50), FOREIGN KEY(CustomerID) REFERENCES Customers(CustomerID)); Describe Orders; The first command - Using the data provided I created the Orders table, in the database. The Foreign Key constraint was used to create a relationship between the Orders table and the Customers which linked together the columns from the Orders table to the CustomerID columns and establishes the Foreign Key relationship. Which then ensures that every value entered in the CustomerID column of the Oders table will correspond to the existing and valid CustomerID in the Customers table. The Second Command – Like above with the Describe Tables command, this command shows all of the data was properly and correctly input into the Orders table as well as any constraints present.

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: CREATE TABLE RMA (RMAID INT NOT NULL PRIMARY KEY, OrderID INT, Step VARCHAR(50), Status VARCHAR(15), FOREIGN KEY (OrderID) REFERENCES Orders(OrderID)); Describe RMA; The first command created a table called RMA, which has the RMA ID column that is unique. The NOT NULL constraint ensures that every entry in the column must have a valid and non null value. The PRIMARY KEY constraint designated the RMAID columns as the primary key for the table which ensured that each RMA will have a unique identifier Order ID, Step, Status and Reason column. The second command as with above examples shows the data was correctly input into the table and the table is working properly. 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. Customers Table: LOAD DATA INFILE '/home/codio/workspace/customers.csv ' INTO TABLE Customers FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n';

Explanation: This SQL code represents a data loading operation for the "Customers" table. The "LOAD DATA INFILE" statement is used to import data from a CSV file named "customers.csv" located at '/home/codio/workspace/customers.csv' into the "Customers" table. The "INTO TABLE Customers" clause specifies that the data will be inserted into the "Customers" table. The "FIELDS TERMINATED BY" clause indicates that the fields in the CSV file are separated by commas, while the "LINES TERMINATED BY Trin'" clause specifies the line-ending format in the CSV file. When executed, the database server reads the CSV file's content, matches the comma-separated values to the appropriate columns in the "Customers" table, and inserts the data accordingly. Orders Table; LOAD DATA INFILE '/home/codio/workspace/orders.csv ' INTO TABLE Orders FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n'; Explanation: This SQL code represents a data loading operation for the "Orders" table. The "LOAD DATA INFILE" statement is used to import data from a CSV file named "orders.csv" located at '/home/codio/workspace/orders.csv' into the "Orders" table. The "INTO TABLE Orders" clause specifies that the data will be inserted into the "Orders" table. The "FIELDS TERMINATED BY " clause indicates that the fields in the CSV file are separated by commas, while the "LINES TERMINATED BY Trin" clause specifies the line-ending format in the CSV file. When executed, the database server reads the CSV file's content, matches the comma-separated values to the appropriate columns in the "Orders" table, and inserts the data accordingly. RMA Table; LOAD DATA INFILE '/home/codio/workspace/rma.csv ' INTO TABLE RMA FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n'; Explanation: I used this SQL code for a data loading operation for the "RMA" table. The "LOAD DATA INFILE" statement is used to import data from a CSV file named "rma.csv" located at '/home/codio/workspace/riga.csv' into the "RMA" table. The "INTO TABLE RMA" clause specifies that the data will be inserted into the "RMA" table. The "FIELDS TERMINATED BY ","' clause indicates that the fields in the CSV file are separated by commas, while the "LINES TERMINATED BY "Ir\n" clause specifies the line-ending format in the CSV file. When executed, the database server reads the CSV file's content, matches the comma-separated values to the appropriate columns in the "RMA" table, and inserts the data successfully. 4. 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

SELECT COUNT(*) FROM Customers INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID WHERE UPPER(Customers.City) = 'FRAMINGHAM' AND UPPER(Customers.State) = 'MASSACHUSETTS'; 'FRAMINGHAM', 'MASSACHUSETTS'. It combines the "Customers" and "Orders" tables using an "INNER JOIN" based on the matching "CustomerlD" column, ensuring that only customers with orders are included. The "WHERE" clause further filters the data, selecting customers from the specified city and state in a case-insensitive manner using the "UPPER()" function. The "COUNT(*" function aggregates the data and returns the count of orders. The output shows that there are 505 orders placed by customers in 'FRAMINGHAM', 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 SELECT COUNT(*) FROM Customers WHERE UPPER(Customers.state) = 'MASSACHUSETTS'; I performed this query on the database table Customers, it selects the counts and number of rows where the state of the customer is, Massachusetts in this case. The results showed the records to be 982.  Write a SQL query to insert four new records into the Orders and Customers tables using the following data:

The INSERT statement added four rows with distinct "CustomerID" values

along with their corresponding first names, last names, street addresses, cities, states, zip codes, and telephone numbers. The query's result shows that the newly inserted data matches the values provided in the INSERT statement. Each new record contains accurate information for the first name, last name, street address, city, state, zip code, and telephone number. Since there are no duplicate warnings or errors reported, it confirms that all the inserts were completed without any issues or conflicts. Overall, the successful retrieval of the inserted data using the SELECT query demonstrates that the records were effectively added to the "Customers" table in the database.
