Tackle Real World Data Challenges with These SQL Key Queries...
Scenario 1: Calculating Average
Question:
You have a table Employees with columns EmployeeID, Department, and Salary. Write an SQL query to find the average salary for each department.
Answer:
Assuming the table Employees with columns EmployeeID, Department, and Salary
SELECT Department,
AVG(Salary) AS AverageSalary
FROM Employees
GROUP BY Department;
Scenario 2: Finding Top Performers
Question:
You have a table Sales with columns SalesPersonID, SaleAmount, and SaleDate. Write an SQL query to find the top 3 salespeople with the highest total sales.
Answer:
Assuming the table Sales with columns SalesPersonID, SaleAmount, and SaleDate
SELECT SalesPersonID,
SUM(SaleAmount) AS TotalSales
FROM Sales
GROUP BY SalesPersonID
ORDER BY TotalSales DESC
LIMIT 3;
Scenario 3: Date Range Filtering
Question:
You have a table Orders with columns OrderID, OrderDate, and Amount. Write an SQL query to find the total amount of orders placed in the last 30 days.
Answer:
Assuming the table Orders with columns OrderID, OrderDate, and Amount

Many people ask this common question “Can I get a job with just SQL and Excel?” or “Can I get a job with just Power BI and Python?”.
The answer to all of those questions is yes.
There are jobs that use only SQL, Tableau, Power BI, Excel, Python, or R or some combination of those.
However, the combination of tools you learn impacts the total number of jobs you are qualified for.
For example, let’s say with just SQL and Excel you are qualified for 10 jobs, but if you add Tableau to that, you are qualified for 50 jobs.
If you have a success rate of landing a job you’re qualified for of 4%, having 5 times as many jobs to go for greatly improves your odds of landing a job.
Does this mean you should go out there and learn every single skill any data analyst job requires?
NO!
It’s about finding the core tools that many jobs want.
And, in my opinion, those tools are SQL, Excel, and a visualization tool.
With these three tools, you are qualified for the majority of entry level data jobs and many higher level jobs.
So, you can land a job with whatever tools you’re comfortable with.
But if you have the three tools above in your toolbelt, you will have many more jobs to apply for and greatly improve your chances of snagging one.

5 Handy Tips to Master Data Science ⬇️
1️⃣ Begin with introductory projects that cover the fundamental concepts of data science, such as data exploration, cleaning, and visualization. These projects will help you get familiar with common data science tools and libraries like Python (Pandas, NumPy, Matplotlib), R, SQL, and Excel
2️⃣ Look for publicly available datasets from sources like Kaggle, UCI Machine Learning Repository. Working with real-world data will expose you to the challenges of messy, incomplete, and heterogeneous data, which is common in practical scenarios.
3️⃣ Explore various data science techniques like regression, classification, clustering, and time series analysis. Apply these techniques to different datasets and domains to gain a broader understanding of their strengths, weaknesses, and appropriate use cases.
4️⃣ Work on projects that involve the entire data science lifecycle, from data collection and cleaning to model building, evaluation, and deployment. This will help you understand how different components of the data science process fit together.
5️⃣ Consistent practice is key to mastering any skill. Set aside dedicated time to work on data science projects, and gradually increase the complexity and scope of your projects as you gain more experience.
