Managing donation receipts for a charitable organization can be a chaotic task if not properly organized. This calls for the need to create a robust database management system to handle these receipts efficiently. Structured Query Language (SQL) comes in handy in creating such a system due to its powerful data manipulation capabilities.
Database Design
The donation receipt management system will consist of two tables: The *Donor* table and the *Donation* table. The *Donor* table will hold donor information while the *Donation* table will handle donation details.
|
1 2 3 4 5 6 7 8 |
CREATE TABLE Donor( Donor_ID INT PRIMARY KEY, First_Name VARCHAR(50), Last_Name VARCHAR(50), Email VARCHAR(100) ); |
*Donor* table will consist of the donor’s unique ID, first name, last name and contact email. Each record in this table represents a unique donor.
|
1 2 3 4 5 6 7 8 |
CREATE TABLE Donation( Donation_ID Int Primary Key, Donor_ID INT Foreign Key REFERENCES Donor(Donor_ID), Donation_Amount FLOAT, Donation_Date DATE ); |
Similarly, the *Donation* table will have a unique donation ID, donor ID (which corresponds to the Donor table, thus creating a relationship between the two tables), donation amount and the date of the donation.
Querying the Database
With the Donor and Donation tables now set up, we can run some SQL queries to populate and manipulate the data.
Inserting Data
Filling up the tables with data is done using the INSERT statement:
|
1 2 3 4 5 6 7 |
INSERT INTO Donor VALUES (1, 'John', 'Doe', <a href="mailto:'johndoe@gmail.com'" >'johndoe@gmail.com'</a>); INSERT INTO Donation VALUES (1, 1, 150.00, '2021-09-15'); |
This adds a donor named John Doe and a donation of $150.00 from him on 15th September 2021.
Retrieving Receipts
Now, if we need to generate a receipt for a specific donation, we can perform a JOIN operation on the two tables:
|
1 2 3 4 5 6 |
SELECT Donor.First_Name, Donor.Last_Name, Donation.Donation_Amount, Donation.Donation_Date FROM Donation JOIN Donor ON Donor.Donor_ID = Donation.Donor_ID WHERE Donation.Donation_ID = 1; |
This will retrieve all details required for the receipt of the first donation.
Through SQL, it is much simpler to manage, update, and retrieve donation receipts at any time!
Conclusion
Through well-structured SQL tables and appropriate SQL queries, a donation receipt management system creates order and efficiency in managing donation data for charitable organizations. The SQL code provided in this article serves as a basic example and can be modified and expanded upon to cater to more specific situations and requirements.
