Here is the solution of last post:

1.Scenerio solution - LEFT JOIN Used:

In this scenario, we will use a LEFT JOIN to retrieve all records from the "employees" table and only the matching records from the "departments" table.

SELECT employees.*, departments.name AS department_name
FROM employees
LEFT JOIN departments ON employees.department_id = departments.id;

2.Scenerio solution - LEFT JOIN Used:

In this scenario, we will use a LEFT JOIN to retrieve all records from the "orders" table and only the matching records from the "customers" table.

SELECT orders.*, customers.name, customers.email
FROM orders
LEFT JOIN customers ON orders.customer_id = customers.customer_id;



Hope it helps :)

You're a data analyst working for a retail company that wants to optimize its sales strategies. The company has a SQL Server database that contains various tables related to sales transactions, customer information, product details, and store locations. Your task is to analyze the data and provide insights to improve sales performance.

𝐐𝐮𝐞𝐬𝐭𝐢𝐨𝐧 𝟏:
Using SQL Server, how would you determine the top-selling products for the current month?
𝐀𝐧𝐚𝐥𝐲𝐳𝐞𝟏:
To determine the top-selling products for the current month, I would start by querying the sales transactions table to retrieve all sales made within the current month. I would then join this table with the product table using the product ID to get the product names and group the results by product name while summing up the quantities sold. Finally, I would order the results by the total quantity sold in descending order and limit the output to the top N products.

𝐐𝐮𝐞𝐬𝐭𝐢𝐨𝐧 𝟐:
How would you analyze customer purchasing behavior to identify potential upsell or cross-sell opportunities?
𝐀𝐧𝐚𝐥𝐲𝐳𝐞 𝟐:
To analyze customer purchasing behavior and identify upsell or cross-sell opportunities, I would examine the sales transactions table and look for patterns in customer buying habits. This could involve identifying frequently co-purchased products or analyzing the average order value per customer. Additionally, I might segment customers based on their purchase history, demographics, or other relevant factors to tailor specific upsell or cross-sell strategies.

𝐐𝐮𝐞𝐬𝐭𝐢𝐨𝐧 𝟑:
How would you assess the performance of different store locations in terms of sales revenue?
𝐀𝐧𝐚𝐥𝐲𝐳𝐞 𝟑:
To assess the performance of different store locations in terms of sales revenue, I would query the sales transactions table and join it with the store locations table using the store ID. Then, I would group the results by store location and calculate the total sales revenue for each location by summing up the transaction amounts. Finally, I would order the results by sales revenue in descending order to identify the top-performing locations.
