Populating the QuantigrationRMA Database and Running Queries

Posted on | by Linus | Leave a Comment on Populating the QuantigrationRMA Database and Running Queries

Overview
It’s now time to populate the QuantigrationRMA database from the Module Three major activity with records and run some basic queries against those tables. You’ll need to import data from the CSV data files into the tables, perform queries against those tables, and create an output listing to the screen of the query results.
Description of QuantigrationRMA Entity Relationship Diagram
An entity relationship diagram (ERD) is a visual representation of a database’s objects and relationships between those objects. It is a blueprint for creating a database, its tables (entities), and their attributes (fields). It also shows the data types and the relationships between entities (cardinality constraints) and keys in each table. In our example, we have three tables named customers, orders, and rma. These tables are the boxes that have several fields such as FirstName, LastName, OrderID, and so on. Each table also contains a primary key denoted by “PK” on the ERD. There is a standard notation called crow’s feet that shows the connection between tables. These lines represent different entity relation types such as one-to-one (1:1) or one-to-many (1:N), as visually depicted in the ERD.
Directions
In the Module Three Major Activity, you created a customer return merchandise authorization (RMA) database using SQL commands. To complete your objectives in this activity, follow these directions:
Before you begin, do the following:Make sure to download the Module Four Major Activity Database Documentation Template for this assignment. You’ll need to place your answers and screenshots in this document and then submit it for grading.
Check the Database Documentation Template Example for clarity on expectations of what yours should look like.
Make sure to review the example RMA ERD that you should be using as a guide before you begin.
Review the module resources on how to capture screenshots, if necessary.
Please note before you begin that the three data files being used for this project are preloaded into Codio:
rma.csv
customers.csv
orders.csv
Import the data from each file into tables.
Use the QuantigrationRMA 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’ll perform this step three times, once for each table.
Write basic queries against imported tables to organize and analyze targeted data.
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.
Write an SQL query that returns the count of orders for customers located only in the city of Framingham, Massachusetts.
This query will use a table join between the Customers and Orders tables. The query will also use a WHERE clause.
How many records were returned?
Write an SQL query to select all of the customers located in the state of Massachusetts.
Use a WHERE clause to limit the number of records in the customers table to only those that are located in Massachusetts.
Record an answer to the following question: How many records were returned?

Guide to Populating the QuantigrationRMA Database and Running Queries

Step 1: Understand the Database and the ERD

The QuantigrationRMA database consists of three main tables: Customers, Orders, and RMA (Return Merchandise Authorization). The Entity Relationship Diagram (ERD) visually depicts how these tables are related. Here’s a breakdown of each table and its relationship with others:

  • Customers Table: Contains information about the customers, such as their FirstName, LastName, Email, etc.
  • Orders Table: Contains details of customer orders, such as OrderID, CustomerID (foreign key referencing the Customers table), OrderDate, and the amount spent.
  • RMA Table: Contains records for merchandise returns, including ReturnID, OrderID (foreign key referencing Orders table), ReturnDate, and the reason for the return.

The ERD also shows the relationships between these tables:

  • A one-to-many relationship exists between Customers and Orders (one customer can have many orders).
  • A one-to-many relationship exists between Orders and RMA (one order can have many RMAs).

Before proceeding, ensure you understand the database structure based on this ERD.

Step 2: Import Data from the CSV Files into the Tables

To begin, you need to import the data from the provided CSV files into the QuantigrationRMA tables. Follow these general steps:

  1. Open your SQL environment (e.g., MySQL Workbench, SQL Server Management Studio, etc.).
  2. Create the database and tables based on the ERD you have been provided with.
  3. Import the CSV data into the corresponding tables:
    • For Customers, import data related to customer details.
    • For Orders, import data such as the OrderID, CustomerID, OrderDate, and Amount.
    • For RMA, import data like ReturnID, OrderID (to link to Orders), ReturnDate, and ReturnReason.

Example SQL command to import data from a CSV file:

sql
LOAD DATA INFILE '/path/to/customers.csv'
INTO TABLE customers
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
IGNORE 1 ROWS;

Repeat the process for the Orders and RMA tables.

Step 3: Run Basic Queries

Once the data has been imported, you will need to run some basic SQL queries to interact with the data. Below are a few examples of queries you might need to run:

1. Query to View All Customers

This query retrieves all records from the Customers table.

sql
SELECT * FROM customers;

2. Query to View Orders by Customer

This query shows all orders placed by a specific customer (replace customer_id_value with an actual customer ID).

sql
SELECT * FROM orders
WHERE CustomerID = customer_id_value;

3. Query to View All RMAs for a Specific Order

This query shows the RMA records for a specific order (replace order_id_value with an actual order ID).

sql
SELECT * FROM rma
WHERE OrderID = order_id_value;

4. Query to Find Customers with Returns

This query retrieves all customers who have made a return by joining the Customers and RMA tables.

sql
SELECT customers.FirstName, customers.LastName, rma.ReturnID
FROM customers
JOIN orders ON customers.CustomerID = orders.CustomerID
JOIN rma ON orders.OrderID = rma.OrderID;

Step 4: Document and Provide Query Outputs

As you perform each query, document the following in your Database Documentation Template:

  • The SQL query you executed.
  • The output or results of the query, showing the relevant data that is returned. If needed, take screenshots of the output to include in your template.

Example for the “View All RMAs for a Specific Order” query:

  • SQL Query: SELECT * FROM rma WHERE OrderID = 101;
  • Query Output: [Insert output from query here, such as a table of returned items for that order].

Step 5: Save and Submit the Documentation

Once you’ve executed the queries and documented the results, save your Database Documentation Template with screenshots and explanations, ensuring you meet the length requirements of 2-3 pages (1-1.5 pages for each question). Submit the completed documentation for grading.

Overview
You have a job interview. They have given you the task of writing a summary that explains how you would write a report for one of their clients. They also want you to give a brief explanation justifying the approach you took.
Directions
The potential employer would like you to use a data set called FleetMaintenanceRecords to complete an analysis of data and summarize your findings using clear language for a nontechnical audience. They’ve asked you to find themes that can be used to help them manage their fleet of trucks. Create a summary of the analysis you conducted that you would use to communicate the findings to stakeholders. Place the deliverables for your instructor and the potential employer in the Analysis and Summary Template.
Analyze the data you’ve been provided to identify themes. Gather the following guiding information:
Review part-replacement frequencies and types and create a hypothesis that can be used by the fleet management team to better deal with vehicle maintenance. You’ll need to create a table called Parts Maintenance and load the data into it. Put this table in the database named after yourself. Load this data set from the ‘/home/codio/workspace’ path and run queries to find the results.
Which parts are being replaced most?
Is there a region of the country that experiences more part failures and replacements than others?
Can you identify a region (Northeast, Southeast, Midwest, Northwest, Southwest) that has more reasons for replacement? Use the Region Definitions sheet to identify states in each region.
How might the fleet maintenance team use the information to update its maintenance schedule? Your response should be supported by the data you’ve found.
Which parts are being replaced most due to corrosion or rust?
Which parts are being replaced because of mechanical failure, like a flat tire or rock through the windshield?
Write a brief summary of your analysis that takes the information from Step 1 and presents it in a way that nontechnical stakeholders can understand.
Outline the approach that you took to conduct the analysis.
What queries did you use to identify trends or themes in the data?
What are the benefits of using these queries to retrieve the information in a way that allows you to provide valuable information to your stakeholders?
Lastly, explain how the functions in the analysis tool (MySQL) allowed you to organize the data and retrieve records quickly.
What to Submit
Submit your responses using the Analysis and Summary Template. Each screenshot and its explanation should be sized to approximately one quarter of the page, with a description written below the screenshot. After you download the template, rename your copy by adding your last name to its file name. This will help organize your work once it has been submitted.

Guide to Structuring Your Report for the Job Interview Task

  1. Understand the Task:
    The goal is to use a dataset called FleetMaintenanceRecords to conduct an analysis and summarize your findings for a nontechnical audience, specifically stakeholders such as a fleet management team. They want you to identify themes from the data to help improve fleet maintenance and management.
  2. Approach to Conducting the Analysis:
    Start by reviewing the data set carefully. This analysis will focus on identifying key trends related to vehicle part failures and replacements. You will look for patterns in part-replacement frequencies, types, and regional differences.
  3. Set Up the Database:
    • Create the Table: First, you will create a table called Parts Maintenance and load the data into this table within a database named after yourself. Use the correct path (/home/codio/workspace) to load the data.
    • Run Queries: Use SQL queries to analyze the dataset, which will help you identify patterns and themes. For instance, you may need to run queries to answer questions like:
      • Which parts are being replaced most?
      • Are there regions that experience more part failures?
      • Which parts are replaced due to corrosion or rust vs. mechanical failure?
    • You will use MySQL to run these queries efficiently.
  4. Writing the Summary:
    Once you’ve conducted your analysis, it’s time to summarize your findings in clear, nontechnical language. Use the following steps:

    • Identify Key Findings: Discuss the parts that are replaced most frequently, the regions with the highest replacement rates, and the causes of these replacements (corrosion, mechanical failure, etc.).
    • Suggest How the Fleet Maintenance Team Can Use the Data: Based on the data, recommend ways the fleet management team can adjust their maintenance schedules, such as prioritizing certain parts or regions with higher replacement rates.
    • Use Simple Language: Since the audience is nontechnical, focus on communicating trends and actionable insights in a straightforward manner.
  5. Outline Your Approach:
    • Explain Your Queries: Clearly outline the SQL queries you used to extract trends from the data. For example, you could explain how you used queries to identify the most frequently replaced parts or to filter data by region.
    • Why These Queries are Useful: Mention that the benefit of using these queries is that they allow you to organize and retrieve specific data points quickly, which makes it easier to draw actionable conclusions.
    • Discuss MySQL Functions: Explain how MySQL functions helped you retrieve and organize the data. For example, using SELECT statements, JOINs, and GROUP BY can help you filter the information based on part types, regions, and failure reasons.
  6. Prepare the Analysis and Summary Template:
    • After conducting your analysis, use the provided Analysis and Summary Template to document your findings and explanations. Insert relevant screenshots of your queries and the resulting data, with each screenshot sized to approximately one quarter of the page.
    • Description Below Each Screenshot: For each screenshot, provide a brief description of what the screenshot shows, such as the query used or the trend identified.
  7. Final Touches:
    • Once you’ve completed the analysis and summary, rename your file with your last name for proper organization.
    • Review your work for clarity and ensure it is organized in a way that nontechnical stakeholders can easily understand.
