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: I went to our learning module and clicked on the lab environment to access our IDE CODIO. I connected to MySQL by typing 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: I created the database QuantigrationUpdates. I am now using it to create my tables. 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:

Describing Orders table. 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: Creating and Describing RMA table. 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. Imported data into each table. 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? There were 505 records returned. This tells us that there are 505 customers that reside 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? There are 982 records returned which tells us that we have 982 customers who live in MA.

 Write a SQL query to insert four new records into the Orders and Customers tables using the following data: Customers Table CustomerID FirstName LastName StreetAddress City State ZipCode 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 I inserted all 4 customers into the customers’ table.
