Understanding customer feedback is key in improving a business’s performance and delivering high-quality products or services. One efficient way of collecting and analysing this data is using SQL (Structured Query Language). In this post, we’ll guide you on how to create a customer feedback and survey response collection system using SQL.
Step 1: Designing Tables
The first step is to design and create the tables that will hold the customer feedback and survey response data. The essential tables you’ll need are the Customers, Surveys, and SurveyResponses tables.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
CREATE TABLE Customers( CustomerID int PRIMARY KEY, FirstName varchar(255), LastName varchar(255), Email varchar(255) ); CREATE TABLE Surveys( SurveyID int PRIMARY KEY, SurveyName varchar(255), SurveyDescription text ); CREATE TABLE SurveyResponses( ResponseID int PRIMARY KEY, SurveyID int FOREIGN KEY REFERENCES Surveys(SurveyID), CustomerID int FOREIGN KEY REFERENCES Customers(CustomerID), Response text ); |
Step 2: Inserting Data
After creating the tables, the next step is to insert some data into them. Here is how you can do this:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
INSERT INTO Customers (CustomerID, FirstName, LastName, Email) VALUES (1, 'John', 'Doe', <a href="mailto:'johndoe@example.com'" >'johndoe@example.com'</a>), (2, 'Jane', 'Doe', <a href="mailto:'janedoe@example.com'" >'janedoe@example.com'</a>); INSERT INTO Surveys (SurveyID, SurveyName, SurveyDescription) VALUES (1, 'Product Satisfaction', 'A survey about our product'); INSERT INTO SurveyResponses (ResponseID, SurveyID, CustomerID, Response) VALUES (1, 1, 1, 'Great product'), (2, 1, 2, 'Everything was perfect'); |
Step 3: Querying the Data
With these tables in place and populated with some data, you can query the data. For example, to view all the responses for a specified survey, you can do:
|
1 2 3 4 5 6 |
SELECT Customers.FirstName, Customers.LastName, SurveyResponses.Response FROM Customers INNER JOIN SurveyResponses ON Customers.CustomerID = SurveyResponses.CustomerID WHERE SurveyResponses.SurveyID = 1; |
Conclusion
That’s a basic guide on how to create a customer feedback and survey response collection system using SQL. Further improvements could be adding more tables to store more detailed information or using more complex queries for better data analysis.
