Quandgration RMA Entity Relationship Diagram
Directions
In the Module Three Major Activity, you created a customer return merchandise authorization (RMA) database using SQL commands.
1. Import the data from each file into tables.
A. Use the QuantigrationRMA database, the three tables you created, and the three CSV files preloaded into Codio.
B. Use the import utility of your database program to load the data from each file into the table of the same name. Perform this step three times, once for each table.
2. Write basic queries against imported tables to organize and analyze targeted data A.
For each query, include a screenshot of the query and its output. You should also include a 1- to 3-sentence description of the output.
B. Write an SQL query that returns the count of orders for customers located only in the city of Framingham, Massachusetts.

ii. How many records were returned?
C. 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 that are located in Massachusetts.
ii. Record an answer to the following question: How many records were returned?
