In today’s digital age, handling job applications is a vast process that requires careful management. With the use of SQL (Structured Query Language), we can create a comprehensive system to review and provide feedback on job applications. In this blog post we’ll take a step-by-step approach to create a job application review system using SQL.
Structure of the Database
The first step in creating this system is to design a database that will store all our information. We’ll start by creating three tables: Applicants, Jobs and Applications.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
CREATE TABLE Applicants ( Applicant_ID INT PRIMARY KEY, First_Name VARCHAR(40), Last_Name VARCHAR(40), Email VARCHAR(255) ); CREATE TABLE Jobs ( Job_ID INT PRIMARY KEY, Job_Title VARCHAR(255), Job_Description TEXT ); CREATE TABLE Applications ( Application_ID INT PRIMARY KEY, Applicant_ID INT, Job_ID INT, Application_Date DATE, Status VARCHAR(255), Feedback TEXT, FOREIGN KEY (Applicant_ID) REFERENCES Applicants(Applicant_ID), FOREIGN KEY (Job_ID) REFERENCES Jobs(Job_ID) ); |
With these tables, we can keep track of our applicants, the jobs posted by the company, and the applications received by each job post.
Entering Data into Database
Once we’ve structured our database, we need to populate it with data. Here’s an example of how we can insert data into the Applicants and Jobs table.
|
1 2 3 4 5 6 7 8 9 |
INSERT INTO Applicants 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 Jobs VALUES (1, 'Software Engineer', 'Design and develop software systems'), (2, 'Data Analyst', 'Analyze data and create reports'); |
Reviewing Applications
We can review the portions of applications by executing SQL queries. For example, if we want to view applications for the ‘Data Analyst’ position, we can execute the following SQL script:
|
1 2 3 4 5 6 7 |
SELECT Applications.Application_ID, Applicants.First_Name, Applicants.Last_Name, Applications.Application_Date, Applications.Status FROM Applications JOIN Jobs ON Applications.Job_ID = Jobs.Job_ID JOIN Applicants ON Applications.Applicant_ID = Applicants.Applicant_ID WHERE Jobs.Job_Title = 'Data Analyst'; |
Providing Feedback to Applications
The last step is providing feedback to the applicants. Feedback can be updated on the Applications table utilizing an UPDATE statement.
|
1 2 3 4 5 |
UPDATE Applications SET Feedback = 'Your application has been reviewed and you have been shortlisted for the next round.' WHERE Application_ID = 1; |
In conclusion, using SQL for a job application review and feedback system can automate the process and make it systematic and efficient. SQL can handle large data logically and provide actionable insights to help companies in the recruitment process.
