For an instructor lead, in-depth look at learning SQL click below.
If you’re eager to take charge of your personal finance by understanding your spendings and planning your budget, SQL is a fantastic tool to consider. Building a personal finance budget planning and expense tracking system with SQL allows you to make data-driven decisions to secure your financial future.
Setting Up Your Database
To kick-start this project, we require a relational database. In this demonstration, we’ll utilize SQLite due to its simplicity and portability. Here’s the SQL code to setup our database:
|
1 2 3 4 5 6 7 8 |
CREATE TABLE Expenses( ID INTEGER PRIMARY KEY, Category TEXT NOT NULL, Amount REAL NOT NULL, ExpenseDate DATE NOT NULL ); |
This simple table captures necessary information about an expense: id, expenditure category, amount spent, and the date of expenditure.
Inserting Data into Our Database
Once we have our database, the next step is to fill it up with data. The following is an example to insert data into our Expenses table:
|
1 2 3 4 5 6 |
INSERT INTO Expenses(Category, Amount, ExpenseDate) VALUES('Groceries', 55.75, '2022-02-01'), ('Rent', 850.00, '2022-02-01'), ('Transportation', 75.50, '2022-02-02'); |
In this example, we are added three different transactions under the categories: Groceries, Rent, and Transportation.
Tracking Expenditure
Through the following SQL command, you can quickly fetch the total expense for a specific category in a given month:
|
1 2 3 4 5 6 |
SELECT Category, SUM(Amount) AS TotalAmount FROM Expenses WHERE strftime('%Y-%m', ExpenseDate) = '2022-02' GROUP BY Category; |
Conclusion
In this blog, we’ve provided a simplistic depiction of how to devise a personal budget planner and expense tracker using SQL. Note that this is a rudimentary example and real-world scenarios would require a more complex database design to incorporate other factors such as varying income, allocation for savings, investments, debt repayment, etc. The beauty of SQL lies in its versatility and ability to handle complex scenarios with ease, thus making it an excellent tool for personal finance management.
