Recently I found, some of my friends refreshing Java language skills. I asked them why.

They told me many digital applications need proficiency in Java skill.

Java is the top skill, and popular in customization of all the tools involved in digital applications. 

From the above conversation, I can say that at least core Java everyone should be proficient. In addition to that, Java once upon a time popular as web development language.Since Java is being used in all modern applications. 

Of course, there are many other popular languages. Those are Python and Scala.

 

Top List of  Java Applications
  1. Robotic process automation-Daily activities in any offices can be automated with Robotic process automation. Java is the language in this scenario to write backend scripts.
  2. Artificial Intelligence-Each AI application involves some sort of programming logic. Where it validates user input and sends back output. The backend logic often is written in Java.
  3. Full stack development-In this area, web development modernization, and maintenance jobs are more. So to work on these applications you need Java. Java is popular for the past two decades, and many applications already are written using it.
  4. Migration to cloud-The tools involved is CloudFormation need skills in Java. Since all the customizations need proficiency in basic Java.

SQL Query: 3 Methods for Calculating Cumulative SUM

SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than...

 Here are five popular SQL queries frequently used in data analysis. 1. SELECT with Aggregations Summarize data by calculating aggregates like counts, sums, averages, etc. SELECT department, COUNT(*) as employee_count, AVG(salary) as average_salary FROM employees GROUP BY department; 2. JOIN Operations  Combine data from multiple tables based on a related column. SELECT e.employee_id, e.name, d.department_name FROM employees e JOIN departments d ON e.department_id = d.department_id; 3. WHERE Clause for Filtering Filter records based on specified conditions. SELECT * FROM sales WHERE sale_date BETWEEN '2024-01-01' AND '2024-12-31'   AND amount > 1000; 4. ORDER BY Clause for Sorting Sort results in ascending or descending order based on one or more columns. SELECT product_name, price FROM products ORDER BY price DESC; 5. GROUP BY with HAVING Clause Group records and apply conditions to the aggregated results. SELECT department, SUM(salary) as total_salaries FROM employ...
